ACI Worldwide, a payment systems company headquartered in Naples, Florida, powers electronic payments and banking for more than 5,000 financial institutions, retailers, billers and processors around the world.

ACI software enables $13 trillion in payments each day, processing transactions for more than 250 of the leading global retailers, and 21 of the world’s 25 largest banks.

Through our comprehensive suite of software products and hosted services, we deliver a broad range of solutions for payments processing; card and merchant management; online banking; mobile, branch and voice banking; fraud detection; trade finance; and electronic bill presentment and payment.

ACI’s products and services are designed to facilitate electronic payments and are used principally by financial institutions, retailers and electronic payment processors.

ACI’s portfolio of products generally addresses three primary market segments: Retail banking, including debit and credit card issuers Wholesale banking, including corporate cash management and treasury management operations Retailers

ACI was founded in Omaha, Nebraska in 1975 to develop software for communications applications making use of the new NonStop computers from the then Tandem Computers.

Many early projects involved building systems to handle ATMs, front ending the bank core banking systems, which led to the launch of the first product, BASE24, in 1982.

Over time BASE24 was expanded to service transactions from other channels such as POS terminals and branch systems. And the product portfolio grew to cover more functions around card transactions such as clearing and settlement and fraud detection. As the product portfolio expanded, the hardware utilised for these products was also expanded to include suppliers including IBM, HP, Stratus and Sun Microsystems.

In the 1990s ACI’s product range was extended to cover wholesale banking payments with solutions for ACH transactions and wire transfers leading to the acquisition of IntraNet in 1998,[1] which expanded the product range with the Money Transfer System product.

Since 1995, ACI has been publicly traded on NASDAQ, initially under the name Transaction Systems Architects (TSA), and since July 2007 under the name ACI Worldwide, Inc. (ACIW).[2] Prior to that ACI had periods under US West and Tandem ownership and as a private company.

In November 2009 it was announced ACI would buy Euronet Essentis to expand card issuing and merchant management capabilities[3] and in March 2011 agreement was reached to acquire ISD Corporation to broaden payment product offerings for retailers.[4]

ACI purchased S1 Corporation in Feb 2012 and Distra later that same year.
