                      which time we will open up the call to your questions.

                      At this time, I would like to introduce Dwight Hanson.

Dwight Hanson:        Thanks Bill, and good afternoon.  Today I'll be
                      discussing our fiscal 2003 third quarter financial
                      results.  First, I'll start by highlighting some key
                      financial metrics that we achieved during the quarter.

                      Total revenue was $73.8 million. Operating expenses were
                      $69.1 million, which included a goodwill impairment charge
                      of $9.3 million. Operating income was $4.7 million, with
                      an operating margin of 6.3%. Net loss was $1.9 million and
                      loss per share was 5 cents, both of which reflect the
                      goodwill impairment charge. Operating cash flow was $11.5
                      million. Our cash balance was $100.9 million. And our
                      12-month backlog was $225.9 million.

                      The $73.8 million of revenue is comprised of the
                      following: software license fees of $40.7 million of which
                      $18.9 million was initial license fees, $21.8 million was
                      monthly license fees, maintenance revenue was $20.7
                      million, and services revenue was $12.4 million.

                      Revenues for each of our geographic channels were as
                      follows: United States, $31.9 million; Americas
                      International, $9 million; Europe, Middle East, and
                      Africa, $25.1 million; and Asia Pacific, $7.8 million.
                      Revenues for each business units were as follows: ACI,
                      $56.4 million; Insession, $8.6 million; and IntraNet, $8.8
                      million.

                      Total revenues of $73.8 million represents an increase of
                      6.2% as compared to the third quarter of last year.
                      Increases in license revenue as well as maintenance
                      revenue were the reasons for this increase in total
                      revenues.

                      The increase in license revenue is primarily due to the
                      increase in capacity upgrades that the ACI business unit
                      received during the third quarter and the early completion
                      of certain contracts from fourth quarter backlog. The
                      increase in maintenance revenue reflects the quarter over
                      quarter continued growth of our installed-base of software
                      products and the ACI and Insession business units.

                      Operating expenses for the quarter were $69.1 million,
                      which is an increase of 21.5% as compared to the third
                      quarter of last year. This increase is primarily due to a
                      goodwill impairment charge of $9.3 million, which reflects
                      the write-down of the last component of the goodwill
                      associated with our MessagingDirect business.

                      During the third quarter, we updated our assessment of the
                      MessagingDirect business and concluded that due to the
                      continued slow adoption of secured document delivery
                      technology, it was appropriate to record this charge.

                      All other expenses, other than G&A, decreased quarter over
                      quarter, which reflects the impact of the expense control
                      and reduction efforts that have taken place over the last
                      18 months. The increase in G&A expenses is due to
                      increased professional fees and changes in bad debt
                      expense. The bad debt expense for the third quarter of
                      last year was a negative amount due to adjustments made to
                      the allowance for doubtful accounts.

                      The tax revision of $6.3 million was computed using a 46%
                      effective rate for the third quarter on all items except
                      the goodwill impairment charge, which is a non-deductible
                      item for tax purposes. The corresponding effective rate
                      for the year has been reduced to 52% as a result of a
                      number of tax-planning strategies that were deployed
                      during the third quarter. We continue to implement
                      additional tax-planning strategies in an attempt to
                      further reduce our overall effective tax rate.

                      Generated positive operating cash flow of $11.5 million
                      and our cash balance at the end of the quarter was $100.9
                      million.

                      Our ending backlog was $225.9 million, which is comprised
                      of recurring backlog of $164.3 million and non-recurring
                      backlog of $61.6 million. The recurring components are
                      monthly license fees of $80.4 million, maintenance fees of
                      $79 million, and facilities management fees of $4.9
                      million. And non-recurring components are license fees of
                      $38.7 million and services of $22.9 million.

                      We include in backlog all revenues specified in signed
                      agreements to the extent we believe that recognition of
                      the related revenue will occur within 12 months.

                      Thanks for your time this afternoon. I'll now turn the
                      call over to Mark for his comments on the ACI business
                      unit.

Mark Vipond:          Thank you, Dwight.  Good afternoon, everyone.  I'm here
                      to give you an update on third quarter results for ACI
                      Worldwide.  ACI's revenue for the quarter was $56.4
                      million.

                      Despite the challenging economic conditions that remain
                      throughout the world, ACI was able to find new business
                      during the quarter. Some of the highlights include systems
                      and capacity upgrades over $100,000 at 14 customers. These
                      upgrades took place in all of our geographic regions with
                      several significant contracts in our European operation.
                      These upgrades are an essential element of ACI's business.

                      We expect customers will continue to license additional
                      capacity over time but it is difficult to predict the
                      timing of these events. The number of capacity upgrades in
                      the third quarter was greater than we have received in the
                      past few quarters and contributed to our increased
                      revenues.

                      ACI licensed products to 13 new customers in the quarter.
                      Those products included six BASE24, one NET24, three
                      Proactive Risk Manager, two WINPAY24, and one large U.S.
                      bank -- BB&T Corporation, which we announced yesterday,
                      that licensed our BASE24-es solution to run their ATM
                      network and IBM zSeries server technology.

                      While BB&T is already a customer of TSA due to its use of
                      IntraNet's MTS product, it is a new customer for ACI and
                      represents a significant win for our company. We are
                      pleased with the number of new ACI customers in the
                      quarter. We believe - which we believe illustrates the
                      value our products provide and the long-term strength of
                      our company.

                      ACI licensed seven new applications to existing customers
                      during the quarter. These include licenses of our
                      BASE24-es Enhanced Authorization System, Mobile Top-up,
                      Automated Key Distribution System, Proactive Risk Manager,
                      and new BASE24 add-on products.

                      With the ACI commerce framework and our continued
                      investments in multi-platform integrated payment systems,
                      we believe we are well positioned in our market space. Our
                      investment in BASE24-es and our strategy to evolve our
                      marketing-leading BASE24 product to this new technology
                      have been well received. In addition, the BASE24-es
                      multi-platform solution is generating interest in new
                      markets where we believe we can license more new customers
                      over time.

                      Thanks for your continued interest. I will now introduce
                      Greg Derkacht.

Greg Derkacht:        Thank you, Mark. In summary, during the quarter,
                      we were able to increase our revenue, grow our cash
                      position to over $100 million. As was noted, our operating
                      results were negatively impacted by a non-tax deductible
                      goodwill impairment charge of $9.3 million relating to
                      2001 acquisitions of MessagingDirect.

                      MessagingDirect secured document delivery technology
                      currently is within the ACI Worldwide business unit and
                      has experienced slow adoption rates. Going forward, our
                      plan is to focus on our growth initiatives and continue to
                      manage our cause.

                      As you can see, we have made progress on our effective tax
                      rate but we still have work to do on this particular
                      issue. We will continue to implement additional
                      tax-planning strategies and we believe that by the end of
                      the fiscal year, we will again be in a position to provide
                      revenue and earnings guidance.

                      Two weeks ago, we announced the appointment of David
                      Bankhead as the company's new Chief Financial Officer. We
                      are extremely pleased to have Dave join our team. He comes
                      to us with over 30 years of financial experience and has
                      been a CFO in four other public companies. The search to
                      fill this position was quite extensive and ultimately,
                      Dave's background, including his international track
                      record, made him the right choice.

                      Dave is going to say a few words in our discussion today
                      and plans on fully participating in next quarter's
                      conference call. Thank you very much for your continued
                      interest in TSA.

David Bankhead:       This is David Bankhead.  Thanks, Greg, for the kind
                      words.  I am pleased to be joining the management team.
                      TSA's history of success and innovation in the
                      electronic payment space made this a very easy decision
                      for me.  I believe the company is well positioned to
                      continue to lead in this market and I look forward to
                      contributing to that effort.  Thank you for your
                      interest in TSA and I look forward to working with you
                      in the future.

                      Now I'll turn the call back over to Bill.

Bill Hoelting:        Thank you.  Operator, at this time, we'd like to open up
                      the call to the questions.

Operator:             Certainly.  If you have a question at this time, please
                      press star, then the number 1 on your telephone keypad.
                      Again, that is star, then the number 1 if you have a
                      question.  And we will pause for just a moment to
                      compile the Q&A roster.

                      And your first question is from (Franco Turrinelli) with
                      William Blair.

(Franco Turrinelli):  Good afternoon, gentlemen.  How are you?

Greg Derkacht:        Hi, (Franco).

(Franco Turrinelli):  A very impressive quarter from a point of
                      view of the number of customer additions and capacity
                      upgrades. Is this the light at the end of the tunnel that
                      we've all been waiting for or is this just, you know, some
                      fortuitous timing?

Greg Derkacht:        I would - and I'll let Mark talk to it also -
                      I'll just characterize the environment.  It really has
                      not changed significantly.  The sales cycle delays are
                      still very, very significant and difficult.  It was a
                      good quarter.  We're proud with the results.  But we
                      have not seen anything change significantly,
                      internationally within the U.S. that really signals a
                      change.

Mark Vipond:          Yeah, this is Mark, (Franco).  Boy, you ask the same
                      question every time.  From the capacity upgrades, we
                      were obviously very pleased with the results in the
                      quarter.  But that's, as I said in my comments, it's a
                      bit unpredictable.  Sometimes you run the customers that
                      run it, it clips their capacity volumes, and sometimes
                      you don't.  So that's one a bit unpredictable.

                      Relative to the new customers, yeah, we also were very
                      excited about the number of new customers. A lot of the
                      BASE24, as I said, six new BASE24 customers, we're very
                      excited about BB&T. Does it change anything? We're just
                      still slugging away out in the marketplace and I think
                      we've got some good traction and got some good results.

                      But as Greg said, I don't think the market has materially
                      changed but we are confident that our strategy is a good
                      one for us to attract new customers over time and maybe we
                      saw some sense of that this quarter but I don't know that
                      we can sit there and say it's going to be that way every
                      quarter going forward.

(Franco Turrinelli):  Okay, Mark.  I'll try to come up with some different
                      questions for you.  Hey, you guys always use the same
                      script, why shouldn't I?

Mark Vipond:          Oh, come on.

(Franco Turrinelli):  One question though for you, you know, the
                      customers, as you point out, great roster, great, you
                      know, good diversification against different product - the
                      product as well. My guess is that most of these customers
                      are reasonably significant and probably did not contribute
                      very much to revenue in the quarter but are contributing
                      to that nice backlog that we're seeing right now.

Mark Vipond:          This is Mark.  Yeah, that's absolutely true.  Many of
                      our products - newer products that we have with
                      BASE24-es and some of our additions of PRM and our
                      Payments Manager, because of the revenue recognition
                      rules, they are delayed in terms of when you can
                      recognize them.  They either have to be accepted - there
                      are different criteria when they can be recognized.

                      The only things that we can actually recognize or have
                      confidence in recognizing in a given quarter that we sell
                      are capacity upgrades and, you know, pots and pans --
                      little add-ons to our existing BASE24 customers in the ACI
                      business. So there's little that we can influence or
                      recognize in a given quarter; most of it goes in the
                      backlog before it sells.

(Franco Turrinelli):  One final question, if I may, before handing
                      it back to the others on the call. I realize that you
                      don't feel comfortable providing guidance, however, in the
                      past, we have often seen the September quarter be a pretty
                      strong quarter for you. What's your thinking just kind of
                      heading into this final quarter in terms of customers,
                      budgetary capacity, and in terms of their plans? Any
                      visibility to that, you know, at all that you can share
                      with us?

Mark Vipond:          My answer to that would be it's - the demand level was
                      about the same as it's been for a while.  Yeah, we
                      usually have - this is the end of our fiscal year and so
                      naturally, our sales people are a little bit more
                      aggressive trying to get to their numbers - that you may
                      have some up-tick from that.  But I think the demand
                      level in the marketplace is about the same as we saw it
                      this quarter and the last quarter.  I don't think it's
                      materially changed.

(Franco Turrinelli):  Okay.  Thanks, Mark.  And let me not hand over without
                      a) welcoming David there, and b) thanking Dwight for his
                      service.

Dwight Hanson:        Thanks (Franco), very much.

David Bankhead:       Thank you.

Operator:             Your next question is from (Kevin McLaughlin) with (BDF
                      Investments).

(Kevin McLaughlin):   Hi. (Kevin McLaughlin) (BDF). In previous
                      conference calls, Greg, you mentioned that the Board had
                      given you directions to create a corporate strategy and I
                      think it was relative to the potential for mergers and
                      acquisitions. I was wondering about the market's
                      conditions and the attractiveness of those kinds of
                      opportunities and the company's intentions, please?

Greg Derkacht:        Well, let me say the intentions as far as we're
                      concerned at this point in time is still the same.  We
                      are literally still in the process of finalizations of
                      strategies basically in the directions from the Board.
                      Should, within the September timeframe, have the
                      strategy basically solidly in place, I think at that
                      point in time, we'll be well served to discuss and have
                      an opportunity to discuss our strategy with various
                      people, including the street.

                      So, you know, we're very, very close at this point in
                      time. We're also going through a strategy validation
                      process with an outside firm to assist us in that process.
                      So I think we're getting very, very close.

(Kevin McLaughlin):   Okay.

Greg Derkacht:        And...

(Kevin McLaughlin):   Thank you very much.

Greg Derkacht:        Excuse me.

(Kevin McLaughlin):   No.  I'll let you finish.

Greg Derkacht:        I think the opportunity levels out there are still
                      significant.  And we'll be finished with the process
                      here pretty soon.

(Kevin McLaughlin):   All right.  Thank you very much.  Thanks to Dwight and
                      welcome to David.

Greg Derkacht:        Thank you, (Kevin).

Operator:             Once again, ladies and gentlemen, I would like to remind
                      you, if you have a question, please press star, then 1
                      on your telephone keypad.

                      And your next question is from (Ned Davis) with (Taconic).

(Ned Davis):          Good afternoon, gentlemen, and also a great
                      performance it looks like and welcome, David. Mark, I have
                      a couple of questions. One, the balance sheet, would you
                      describe the situation as sort of somewhat normalized now
                      with respect to receivables, payables, etc.?

                      I know that there was a big effort to kind of improve
                      liquidity back a couple of quarters. Is it sort of
                      stabilized now? Can we expect these ratios to remain
                      roughly where they are? And then I have one other question
                      after that.

Greg Derkacht:        I would say we feel our balance sheet is
                      stabilized at this point in time and hopefully, we can
                      have good continued form from cash and things like that
                      but we do feel it's stabilized.

(Ned Davis):          Okay.  The second question has to do with some of the
                      new contracts.  Let me particularly reference the BB&T
                      transaction.  I take it that's a relatively large
                      transaction about over a period of years in terms of a
                      revenue standpoint?

Mark Vipond:          Well, as with most of our contracts, that was,
                      specifically but generally, we sign a five-year agreement
                      and the product support fees and the monthly license fees
                      are recognizable over five years.

(Ned Davis):          So is it - are they replacing a legacy from
                      another vendor or an in-house legacy? And is this
                      something you think you can, if you will, copy with other
                      large players, either here or overseas?

Mark Vipond:          So the answer to the question on BB&T, yes, they are
                      replacing a legacy system from a vendor that has
                      discontinued support on the IBM zSeries.  And so we are
                      taking over that application.  And can we replicate it?
                      Yeah, we believe we can.

                      This specific application that we're replacing is
                      typically not installed in such a large organization, it's
                      usually in geared towards smaller organizations with
                      anywhere from 50 to 100 ATMs in their network. And BB&T
                      have somewhere in approaching 2000.

                      So I don't know if that replacing that specific
                      application, is that replicatable because there's not that
                      many of them that have that big of a system on that
                      antiquated piece of note.

                      But obviously, one of our strategies relative to driving
                      increased customers and market share is to go after the
                      in-house and the other solutions that run on these
                      platforms that may not have stayed up enough with
                      investments and mandates and the technology that we can
                      eclipse them with our product and also provide additional
                      functionality. That's certainly part of our strategy is to
                      build our market share with our es product.

(Ned David):          Okay.  One last detail, I want to get a clarification.
                      The tax rate effectively was 46% with no impact from the
                      goodwill impairment charge.  But somewhere else it says
                      52% rates of year.  So are you in effect providing a tax
                      rate guidance for the full year at 52%?  Is that - did I
                      understand that correctly?

Dwight Hanson:        Well, the way the process works is you estimate
                      what your rate is for the year and then you apply that to
                      your year-to-date results and then you push out the
                      difference within the current quarter.

(Ned Davis):          Okay.

Dwight Hanson:        So at this point, that's our best estimate of the rate,
                      based on the fact that we know today, because that's how
                      you do it.

(Ned Davis):          So that's for the full year '03 fiscal, the 52%?

Dwight Hanson:        That's correct.

Greg Derkacht:        That's right.

(Ned Davis):          Okay.  So we could - whatever estimate we want to use
                      for the fourth quarter, we could then deduce what the
                      tax rate would be based on using that 52%.  That's kind
                      of what you're saying.

Dwight Hanson:        As long as you apply that to the full year numbers,
                      right.

(Ned Davis):          Right.  Okay.

Dwight Hanson:        Exclusive of that goodwill charge.

(Ned Davis):          Is the 46% rate for this quarter a fluke or is it
                      something that's particularly with David working on this
                      might signal that your tax rate will start pushing towards
                      the normal corporate rate next year?

Greg Derkacht:        Well, we most certainly have the project continuing at
                      this point in time and we'll continue to hopefully apply
                      strategy, which will continue to reduce the rate.  So
                      it's very much indigenous to continue this process to
                      producing effective tax rate.  But obviously, working
                      with the tax authorities is a long-term process and we
                      hopefully will be able to do it at this point in time
                      but we make no guarantees of that.

(Ned Davis):          Okay.  Thank you.

Greg Derkacht:        Thank you, (Ned).

Operator:             And your next question is from (Nick Fisken) with
                      (Stephens Inc.).

(Nick Fisken):        Hi.  A question on the increasing G&A; Dwight, you said
                      - you gave a couple reasons why and I wanted to hear
                      those again.  And then b), can you give us some more
                      detail on the increase of the bad debt expense, please?

Dwight Hanson:        Okay.  Well, it's, like I said, the increase is
                      primarily due to increased professional fees that we
                      incurred this year as compared to the third quarter of
                      last year.  And the bad debt expense that we're - that
                      we have in the third quarter this year, when you compare
                      it against the third quarter of last year, it was
                      actually a negative bad debt expense because we adjusted
                      our overall bad debt allowance.

                      So it's more of a function over an abnormal amount a year
                      ago than it is an unusual amount in the current quarter
                      for this year, (Nick). It's really a function of that and
                      that's what I was trying to convey in my remarks earlier.

(Nick Fisken):        Now the increased professional fees and ongoing expense...

Dwight Hanson:        Well...

(Nick Fisken):      ...is G&A going to be the same level on a go-forward basis?

Greg Derkacht:        Let me kind of come on that, (Nick). Basically,
                      the G&A - the increase is related to the tax project
                      that's going on and so at least for one more quarter,
                      we'll see that continue. So at this point in time, I think
                      the G&A will be right at somewhat at that level or at
                      least the next quarter.

(Nick Fisken):        Okay, thanks, and congrats on the progress.

Greg Derkacht:        Thank you.

Dwight Hanson:        Thanks.

Operator:             And you have a follow-up from (Franco Turrinelli) with
                      William Blair.

(Franco Turrinelli):  Actually, I think (Nick) took my question but
                      just to confirm, there was a step-up sequentially in the
                      G&A from the first quarter and I'm assuming that that is
                      related to the tax project that you just talked about.

Dwight Hanson:        Yes.

(Franco Turrinelli):  Okay.  Thanks.

Operator:             And at this time, there are no further questions.  Do
                      you have any closing remarks?

Bill Hoelting:        We thank you all for participating in our Q3 conference
                      call and look forward to the next conference call.
                      Thank you for attending today.

Greg Derkacht:        Thank you very much.

Operator:             This concludes today's teleconference.  You may now
                      disconnect.


                                       END
