(OMAHA, Neb. -- October 26, 2004) -- Transaction Systems Architects, Inc.
(Nasdaq: TSAI), a leading global provider of enterprise e-payments software,
announced today that revenue for the fourth quarter ended September 30, 2004 was
$69.7 million, a decrease of 2.9 percent from the same quarter last year. Net
income for the quarter was $10.0 million, or $.26 per diluted share, compared to
net income of $9.1 million, or $.25 per diluted share for the same period last
year, an increase of 9.8 percent and 4.0 percent, respectively.

For the fourth quarter of fiscal 2004, revenue was comprised of software license
fees of $36.2 million, maintenance fees of $21.7 million and services fees of
$11.8 million. The Company's recurring revenue was $43.6 million, or 63 percent
of total revenue, and non-recurring revenue was $26.1 million, or 37 percent of
total revenue. Recurring revenue consisted of monthly license fees of $19.6
million, maintenance fees of $21.7 million and facilities management fees of
$2.3 million.

Operating income for the quarter was $12.3 million, with an operating margin of
17.6 percent, compared to operating income of $11.9 million, with an operating
margin of 16.5 percent, in the fourth quarter of fiscal 2003. Operating cash
flow was $12.7 million compared to operating cash flow of $11.9 million in the
fourth quarter of fiscal 2003, an increase of 6.7 percent. The cash balance as
of September 30, 2004 was $169.6 million.

During the quarter, the Company added twenty-one new customers while maintaining
a worldwide presence of 76 countries. ACI Worldwide, the Company's largest
business unit, added ten new customers during the quarter. Solutions licensed
included BASE24(R), BASE24-es(TM), ACI Proactive Risk Manager(TM), WINPAY24(TM),
and ACI e-Courier(TM). ACI Worldwide also licensed capacity upgrades to 19
customers and licensed new applications to 17 existing customers during the
fourth quarter.

Insession Technologies, the Company's e-infrastructure business unit, added 11
new customers and licensed 11 new applications to existing customers during the
quarter. IntraNet, the Company's corporate banking software provider, licensed
five add-on modules and signed 30 service contracts with its existing customers
during the quarter.

The Company completed the fourth quarter of fiscal 2004 with $229.6 million in
backlog. Included in backlog are all software license fees, maintenance fees and
services specified in executed contracts to the extent that the Company believes
that recognition of the related revenue will occur within the next twelve
months. Recurring backlog includes monthly license fees, maintenance fees and
facilities management fees and amounted to $168.1 million. Non-recurring backlog
includes other software license fees and services and amounted to $61.5 million.

For the fiscal year ended September 30, 2004, the Company's revenue was $292.8
million, compared to $277.3 million for fiscal 2003, an increase of 5.6 percent.
Operating income in fiscal 2004 was $54.8 million, with an operating margin of
18.7 percent, compared to $35.3 million, with an operating margin of 12.7
percent, in fiscal 2003.

Net income for the year ended September 30, 2004 was $46.7 million, or $1.23 per
diluted share, compared to $14.3 million, or $.40 per diluted share, for fiscal
2003, an increase of 226 percent and 208 percent, respectively. The net income
results for fiscal 2004 include a net one-time tax benefit of $10.6 million, or
$.28 per diluted share, in the third quarter. This net one-time tax benefit is
attributed primarily to certain tax restructurings and associated tax elections
related to the Company's MessagingDirect Ltd. subsidiaries.

"We are pleased with our fiscal 2004 results, as we have made significant
progress during the year in a number of key areas," said Gregory D. Derkacht,
President and CEO. "We will continue to invest in our newer initiatives. We look
for these initiatives to provide additional market opportunities in fiscal 2005.
In addition, we continue to consider external growth opportunities that will
leverage our key strengths."

The Company's revenue estimate for fiscal 2005 is $279 million to $308 million
and its earnings per diluted share estimate for fiscal 2005 is $.79 to $.94.

The Company will provide further details regarding its financial performance for
the fourth quarter of fiscal 2004 in its scheduled teleconference to be held
Tuesday, October 26, 2004 at 4:00 pm CDT. Interested persons may access a
real-time audio broadcast of the teleconference at: www.tsainc.com/investors.
The webcast will be archived for ten days after the teleconference at this same

Forward-Looking Statements

This press release contains forward-looking statements based on current
expectations that involve a number of risks and uncertainties. Generally,
forward-looking statements do not relate strictly to historical or current
facts, and include words or phrases such as "management anticipates," "the
Company believes," "the Company anticipates," "the Company expects," "the
Company plans," "the Company will," "the Company is well positioned" and words
and phrases of similar impact, and include but are not limited to statements
regarding future operations, business strategy and business environment. The
forward-looking statements are made pursuant to safe harbor provisions of the
Private Securities Litigation Reform Act of 1995. Forward-looking statements in
this press release include the Company's recurring and non-recurring backlog,
the Company's revenue estimate and EPS estimate for fiscal 2005, and statements
that the Company expects initiatives to provide market opportunities, and the
Company will consider external growth opportunities that will leverage our key
strengths.

The Company's actual results could differ materially from the results discussed
in its forward-looking statements.

The Company operates in a rapidly changing technological and economic
environment that presents numerous risks. Many of these risks are beyond the
Company's control and are driven by factors that often cannot be predicted. The
following discussion highlights some of these risks:

   o     The Company's backlog estimate is based on management's assessment of
         the customer contracts that exist as of the date the estimate is made.
         A number of factors could result in actual revenues being less than the
         amounts reflected in backlog. The Company's customers may attempt to
         renegotiate or terminate their contracts for a number of reasons,
         including mergers, changes in their financial condition, or general
         changes in economic conditions in their industries or geographic
         locations, or the Company may experience delays in the development or
         delivery of products or services specified in customer contracts.
         Accordingly, there can be no assurance that contracts included in
         recurring or non-recurring backlog will actually generate the specified
         revenues or that the actual revenues will be generated within a
         twelve-month period.

   o     The Company continues to evaluate the claims made in various lawsuits
         filed against the Company and certain directors and officers relating
         to its restatement of prior consolidated financial results. The Company
         intends to defend these lawsuits vigorously, but cannot predict their
         outcomes and is not currently able to evaluate the likelihood of its
         success or the range of potential loss, if any. However, if the Company
         were to lose any of these lawsuits or if they were not settled on
         favorable terms, the judgment or settlement could have a material
         adverse effect on its financial condition, results of operations and
         cash flows.

         The Company has insurance that provides an aggregate coverage of $20.0
         million for the period during which the claims were filed, but cannot
         evaluate at this time whether such coverage will be available or
         adequate to cover losses, if any, arising out of these lawsuits. If
         these policies do not adequately cover expenses and liabilities
         relating to these lawsuits, the Company's financial condition, results
         of operations and cash flows could be materially harmed. The Company's
         certificate of incorporation provides that it will indemnify and
         advance expenses to its directors and officers to the maximum extent
         permitted by Delaware law. The indemnification covers any expenses and
         liabilities reasonably incurred by a person, by reason of the fact that
         such person is or was or has agreed to be a director or officer, in
         connection with the investigation, defense and settlement of any
         threatened, pending or completed action, suit, proceeding or claim. The
         Company's certificate of incorporation authorizes the use of
         indemnification agreements and the Company enters into such agreements
         with its directors and certain officers from time to time. These
         indemnification agreements typically provide for a broader scope of the
         Company's obligation to indemnify the directors and officers than set
         forth in the certificate of incorporation. The Company's contractual
         indemnification obligations under these agreements are in addition to
         the respective directors' and officers' rights under the certificate of
         incorporation or under Delaware law. However, the indemnification
         agreements typically eliminate the Company's obligation to pay a
         director or officer for any claims to the extent that he or she has
         previously received payment for such claims under any insurance policy,
         the certificate of incorporation or otherwise.

         Additional related suits against the Company may be commenced in the
         future. The Company will fully analyze such suits and intends to
         vigorously defend against them. There is a risk that the
         above-described litigation, as well as any additional suits, could
         result in substantial costs and divert management attention and
         resources, which could adversely affect the Company's business,
         financial condition and results of operations.

   o     New accounting standards, revised interpretations or guidance regarding
         existing standards, or changes in the Company's business practices
         could result in future changes to the Company's revenue recognition or
         other accounting policies. These changes could have a material adverse
         effect on the Company's business, financial condition and results of
         operations.

   o     The Company is subject to income taxes, as well as non-income based
         taxes, in the United States and in various foreign jurisdictions.
         Significant judgment is required in determining the Company's worldwide
         provision for income taxes and other tax liabilities. In addition, the
         Company has benefitted from, and expects to continue to benefit from,
         implemented tax-saving strategies. The Company believes that
         implemented tax-saving strategies comply with applicable tax law.
         However, taxing authorities could disagree with the Company's
         positions. If the taxing authorities are successful in challenging any
         of the Company's tax positions, the Company's financial condition and
         results of operations could be adversely affected.

         The Company's tax positions in its amended income tax returns filed for
         its 1999 through 2002 tax years are the subject of an ongoing
         examination by the Internal Revenue Service ("IRS"). The Company
         believes that its tax positions comply with applicable tax law. This
         examination may result in the IRS issuing proposed assessments that
         could adversely affect the Company's financial condition and results of
         operations.

         Two of the Company's foreign subsidiaries are the subject of a tax
         examination by the local taxing authority. Other foreign subsidiaries
         could face challenges from various foreign tax authorities. It is not
         certain that the local authorities will accept the Company's tax
         positions. The Company believes its tax positions comply with
         applicable tax law and it intends to defend its positions. However,
         differing positions on certain issues could be upheld by foreign tax
         authorities, which could adversely affect the Company's financial
         condition and results of operations.

   o     No assurance can be given that operating results will not vary.
         Fluctuations in quarterly operating results may result in volatility in
         the Company's stock price. The Company's stock price may also be
         volatile, in part, due to external factors such as announcements by
         third parties or competitors, inherent volatility in the technology
         sector and changing market conditions in the software industry. The
         Company's stock price may also become volatile, in part, due to
         developments in the various lawsuits filed against the Company relating
         to its restatement of prior consolidated financial results.

   o     The Company has historically derived a majority of its total revenues
         from international operations and anticipates continuing to do so, and
         is thereby subject to risks of conducting international operations
         including: difficulties in staffing and management, reliance on
         independent distributors, longer payment cycles, volatilities of
         foreign currency exchange rates, compliance with foreign regulatory
         requirements, variability of foreign economic conditions, and changing
         restrictions imposed by U.S. export laws.

   o     The Company's BASE24-es product is a significant new product for the
         Company. If the Company is unable to generate adequate sales of
         BASE24-es, if market acceptance of BASE24-es is delayed, or if the
         Company is unable to successfully deploy BASE24-es in production
         environments, the Company's business, financial condition and results
         of operations could be materially adversely affected.

   o     Historically, a majority of the Company's total revenues resulted from
         licensing its BASE24 product line and providing related services and
         maintenance. Any reduction in demand for, or increase in competition
         with respect to, the BASE24 product line could have a material adverse
         effect on the Company's financial condition and results of operations.

   o     The Company has historically derived a substantial portion of its
         revenues from licensing of software products that operate on HP NonStop
         servers. Prior to its merger with HP, Compaq Computer Corporation
         announced a plan to consolidate its high-end performance enterprise
         servers on the Intel Corp. Itanium microprocessor, which is expected to
         be completed by 2005. Any reduction in demand for the HP NonStop
         servers or in HP's ability to deliver products on a timely basis could
         have a material adverse effect on the Company's financial condition and
         results of operations. The Company has not determined whether
         consolidation of the high-end servers will materially affect the
         Company's business, financial condition or results of operations.

   o     The Company's business is concentrated in the banking industry, making
         it susceptible to a downturn in that industry. Further, banks are
         continuing to consolidate, decreasing the overall number of potential
         buyers of the Company's products and services.

   o     The Company may acquire new products and services or enhance existing
         products and services through acquisitions of other companies, product
         lines, technologies and personnel, or through investments in other
         companies. Any acquisition or investment may be subject to a number of
         risks, including diversion of management time and resources, disruption
         of the Company's ongoing business, difficulties in integrating
         acquisitions, dilution to existing stockholders if the Company's common
         stock is issued in consideration for an acquisition or investment, the
         incurring or assuming of indebtedness or other liabilities in
         connection with an acquisition, and lack of familiarity with new
         markets, product lines and competition. The failure to manage
         acquisitions or investments, or successfully integrate acquisitions,
         could have a material adverse effect on the Company's business,
         financial condition and results of operations.

   o     To protect its proprietary rights, the Company relies on a combination
         of contractual provisions, including customer licenses that restrict
         use of the Company's products, confidentiality agreements and
         procedures, and trade secret and copyright laws. Despite such efforts,
         the Company may not be able to adequately protect its proprietary
         rights, or the Company's competitors may independently develop similar
         technology, duplicate products or design around any rights the Company
         believes to be proprietary. This may be particularly true in countries
         other than the United States because some foreign laws do not protect
         proprietary rights to the same extent as certain laws of the United
         States. Any failure or inability of the Company to protect its
         proprietary rights could materially adversely affect the Company.

   o     There has been a substantial amount of litigation in the software
         industry regarding intellectual property rights. The Company
         anticipates that software product developers and providers of
         electronic commerce solutions could increasingly be subject to
         infringement claims, and third parties may claim that the Company's
         present and future products infringe their intellectual property
         rights. Any claims, with or without merit, could be time-consuming,
         result in costly litigation, cause product delivery delays or require
         the Company to enter into royalty or licensing agreements. A successful
         claim by a third party of intellectual property infringement by the
         Company could compel the Company to enter into costly royalty or
         license agreements, pay significant damages or even stop selling
         certain products. Royalty or licensing agreements, if required, may not
         be available on terms acceptable to the Company or at all, which could
         adversely affect the Company's business.

   o     The Company's software products are complex. They may contain
         undetected errors or failures when first introduced or as new versions
         are released. This may result in loss of, or delay in, market
         acceptance of the Company's products and a corresponding loss of sales
         or revenues. Customers depend upon the Company's products for
         mission-critical applications. Software product errors or failures
         could subject the Company to product liability, as well as performance
         and warranty claims, which could materially adversely affect the
         Company's business, financial condition and results of operations.

Any or all of the forward-looking statements may turn out to be wrong. They can
be affected by inaccurate assumptions or by known or unknown risks and
uncertainties. Many of these factors will be important in determining the
Company's actual future results. Consequently, no forward-looking statement can
be guaranteed. Actual future results may vary materially from those expressed or
implied in any forward-looking statements.

These cautionary statements and any other cautionary statements that may
accompany such forward-looking statements, whether written or oral, expressly
qualify all of the forward-looking statements. In addition, the Company
disclaims any obligation to update any forward-looking statements after the date
of this release unless applicable securities laws require it to do so.

For a detailed discussion of these and other risk factors, interested parties
should review the Company's filings with the SEC, including the Company's Form
10-K filed on December 23, 2003, the Company's Form 10-Q filed on February 17,
2004, the Company's Form 10-Q filed on May 17, 2004 and the Company's Form 10-Q
filed on August 11, 2004.
