NEW YORK, May 24, 2012 (GLOBE NEWSWIRE) -- ACI Worldwide, Inc.
(Nasdaq:ACIW), a leading international provider of payments solutions,
announced today the release of the latest version of ACI Acquirer(TM),
its comprehensive multi-currency system for managing merchant accounts,
histories and settlements. The enhanced ACI Acquirer offers greater
support for U.S. taxation requirements, enhanced interchange fee
processing and expanded features for merchant settlement delay and
deposit reserves.

ACI Acquirer enhancements are complemented by the launch of the newest
version of ACI Interchange(TM), the company's central monetary
transaction manager for clearing card transactions. Both solutions
ensure that acquiring banks and processors remain current with the
latest regulatory developments in the U.S. market. This increases
customers' ability to operate seamlessly in today's highly competitive
merchant acquiring environment. ACI Issuer(TM), ACI Acquirer and ACI
Interchange are installed at more than 70 customers in North America,
Europe and Asia.

Financial institutions require a merchant acquiring solution that
offers flexibility as its premiere feature. The enhanced ACI Acquirer
enables the most flexible pricing, transaction, service and merchant
settlement options on the market today. Some of the new features
include:


  --  Improved functionality for U.S. including taxation calculation and
      reporting, support for NACHA payment file formats and industry
      compliance mandates.
  --  Enhancements which allow merchant acquirers to create highly
      differentiated merchant programs with unique methods for delayed or
      deferred settlement and merchant deposit reserve management
  --  Support for Discover card transaction clearing and settlement.




"The U.S. remains a very competitive and dynamic merchant acquiring
market, subject to a number of essential regulatory requirements and
changes in operating conditions," said David Morem, Executive Vice
President, Global Products and Maintenance, ACI Worldwide. "Merchant
acquirers need a management solution which ensures ongoing compliance
and competitive transaction price points as well as the ability to
better compete in the market through overall pricing flexibility and
customized settlement funding capabilities. That need is fulfilled by
the latest releases of ACI Worldwide's core merchant and card
management solutions."

card and merchant management solutions also includes ACI Issuer for
issuing and supporting all card types, and two complementary products,
