(OMAHA, Neb.-- January 25, 2005)--Transaction Systems Architects, Inc. (Nasdaq:
TSAI), a leading global provider of enterprise e-payments software, announced
today that revenue for the first quarter ended December 31, 2004 was $80.6
million, an increase of 8.9 percent from the same quarter last year. Net income
for the quarter was $12.9 million, or $.34 per diluted share, compared to net
income of $10.0 million, or $.27 per diluted share for the same period last
year, increases of 28.7 percent and 25.9 percent, respectively. Net income and
earnings per diluted share for the first quarter of fiscal 2005 included a $1.2
million foreign exchange loss compared with a $2.4 million foreign exchange gain
during the same quarter last year.

For the first quarter of fiscal 2005, revenues were comprised of software
license fees of $47.8 million, maintenance fees of $22.1 million and services
of $10.7 million. The Company's recurring revenue was $42.9 million, or 53
percent of total revenue, and non-recurring revenue was $37.7 million, or 47
percent of total revenue. Recurring revenue consisted of monthly license fees of
$18.3 million, maintenance fees of $22.1 million and facilities management fees
of $2.5 million.

Operating income was $22.1 million, with an operating margin of 27.4 percent,
compared to operating income of $15.5 million, with an operating margin of 21.0
percent, in the first quarter of fiscal 2004. Operating cash flow was $15.0
million compared to operating cash flow of $11.1 million in the first quarter of
fiscal 2004, an increase of 35.3 percent. Cash, cash equivalents and marketable
securities as of December 31, 2004 were $186.5 million.

During the quarter, the Company added ten new customers while maintaining a
worldwide presence in 76 countries. ACI Worldwide, the Company's largest
business unit, added four new customers during the quarter. Solutions licensed
included BASE24(R) and ACI Proactive Risk Manager(TM). ACI Worldwide also
licensed capacity upgrades to eleven customers and licensed eight new
applications to existing customers during the first quarter.

Insession Technologies, the Company's e-infrastructure business unit, added six
new customers and licensed six new applications to existing customers during the
quarter. IntraNet, the Company's corporate banking software provider, licensed
one capacity upgrade, one new add-on module and signed 33 service contracts with
its existing customers during the quarter.

The Company completed the first quarter of fiscal 2005 with $230.4 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 specified and amounted to $170.9 million.
Non-recurring backlog includes other software license fees and services and
amounted to $59.5 million.

"The Company's strong first quarter financial results provide a good start to
fiscal 2005," said Gregory D. Derkacht, President and CEO. "We remain cautiously
optimistic about the remainder of fiscal 2005 as demand for our solutions remain
steady and we continue to make progress with implementations and delivery of our
newer software solutions." The Company has revised its revenue estimate for
fiscal 2005 from a range of $279 million to $308 million to a range of $285
million to $308 million. The Company has revised its diluted EPS estimate from a
range of $.79 to $.94 to a range of $.86 to $1.00, which excludes the effect of
anticipated accounting rule changes related to expensing of equity-based
compensation.

The Company will provide further details regarding its financial performance for
the first quarter of fiscal 2005 in its scheduled teleconference to be held
Tuesday, January 25, 2005 at 4:00 pm CST. 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
web address.

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 we remain cautiously optimistic about the remainder of fiscal 2005 as
demand for our solutions remain steady and we continue to make progress with
implementations and delivery of our newer software solutions.

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   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/or results of
         operations.

     o   The Company's EPS estimate for 2005 excludes the impact of recording
         expenses associated with equity-based compensation. In December 2004,
         the Financial Accounting Standards Board ("FASB") issued the final
         version of FASB Statement of Financial Accounting Standards ("SFAS")
         No. 123 (Revised 2004), Share-Based Payment. This revised accounting
         standard requires most public companies to record a non-cash expense
         for stock options in their financial statements commencing in the first
         annual or interim period that begins after June 15, 2005. The Company
         does not plan to adopt this revised accounting standard prior to its
         fourth quarter of fiscal 2005. The adoption of SFAS No 123, as revised,
         and the non-cash expense that will be recorded thereby, will reduce the
         Company's EPS.

     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 decided to challenge any of the
         Company's tax positions and were successful in such challenges, the
         Company's financial condition and/or results of operations could be
         adversely affected.

     o   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 has resulted in the IRS issuing proposed adjustments, the
         majority of which relate to the timing of revenue recognition. The IRS
         could issue additional proposed adjustments that could adversely affect
         the Company's financial condition and/or results of operations.

     o   Three of the Company's foreign subsidiaries are the subject of tax
         examinations by the local taxing authorities. 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 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/or results of operations.

     o   No assurance can be given that operating results will not vary from
         quarter to quarter, and any 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/or
         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/or 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. Any reduction in demand for HP NonStop servers, or any change
         in strategy by Compaq Computer Corporation related to support of HP
         NonStop servers, could have a material adverse effect on the Company's
         financial condition and/or results of operations.

     o   The Company's business is concentrated in the financial services
         industry, making it susceptible to a downturn in that industry.
         Consolidation activity among financial institutions has increased in
         recent years. There are several potential negative effects of increased
         consolidation activity. Continuing consolidation of financial
         institutions may result in a fewer number of existing and potential
         customers for the Company's products and services. Consolidation of two
         of the Company's customers could result in reduced revenues if the
         combined entity were to negotiate greater volume discounts or
         discontinue use of certain of the Company's products. Additionally, if
         a non-customer and a customer combine and the combined entity in turn
         decided to forego future use of the Company's products, the Company's
         revenue would decline.

     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/or results of operations.

     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/or 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   From time to time, the Company is involved in litigation relating to
         claims arising out of its operations. Any claims, with or without
         merit, could be time-consuming and result in costly litigation. Failure
         to successfully defend against these claims could result in a material
         adverse effect on the Company's business, financial condition and/or
         results of operations.

     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/or
         cash flows.

     o   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.

     o   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/or results of operations.

     o   Beginning in fiscal 2005, Section 404 of the Sarbanes-Oxley Act of 2002
         will require the Company's annual report on Form 10-K to include (1) a
         report on management's assessment of the effectiveness of the Company's
         internal controls over financial reporting, (2) a statement that the
         Company's independent auditor has issued an attestation report on
         management's assessment of the Company's internal controls over
         financial reporting, and (3) a report by the Company's independent
         auditor on their assessment of the effectiveness of the Company's
         internal controls over financial reporting. There are no assurances
         that the Company will discover and remediate all deficiencies in its
         internal controls, including any significant deficiencies or material
         weaknesses, as it implements new documentation and testing procedures
         to comply with the Section 404 reporting requirements. If the Company
         is unable to remediate such deficiencies or is unable to complete the
         work necessary to properly evaluate its internal controls over
         financial reporting, there is a risk that management and/or the
         Company's independent auditor may not be able to conclude that the
         Company's internal controls over financial reporting are effective.

     o   The Company issued a press release dated September 28, 2004 announcing
         Gregory D. Derkacht's plans to retire as the Company's president and
         chief executive officer not later than June 30, 2006. The Company has
         commenced a search for Gregory D. Derkacht's successor and expects to
         identify such person prior to June 30, 2006. The search, and the
         related transition period, could divert management attention and
         resources away from other operational matters. Additionally, there can
         be no assurance that the Company will be successful in identifying a
         successor president and CEO by June 30, 2006 that meets the Company's
         criteria. If a suitable successor is not identified prior to Gregory D.
         Derkacht's retirement, the resulting uncertainty could adversely affect
         the Company's business and/or its stock price.

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

10-Q filed on February 17, 2004, the Company's Form 10-Q filed on May 17, 2004,
