Trace ACI’s first 30 years

ACI combines a global perspective with local presence to tailor solutions for each customer. Our proven products, domain expertise and 30+ years of experience have earned us a position as trusted provider of gold standard payments solutions.

With over 2,200 employees worldwide and offices in principal cities around the globe, ACI now has one of the most diverse and robust product portfolios in the industry, with application software spanning the length of the e-payments value chain.

ACI was founded in Omaha, Nebraska, US in 1975 to develop software for communications applications making use of the new NonStop computers from the then Tandem organisation. Many of the 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 that product was expanded to service transactions from other channels such as POS terminals and branch systems. And the product portfolio was expanded to cover more functions around card transactions such as clearing and settlement and fraud detection. As the product portfolio was expanded, the hardware utilised for these products was also expanded to include suppliers such as IBM, HP, Stratus and SUN.

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

Early customers were all in the US. In 1981 an Australian bank became a customer starting an international growth path. By 1986, ACI had 131 customers in 14 countries. Supporting this international growth was the development of a series of offices and partners around the world.

Since 1995, ACI has been a public company traded on NASDAQ, initially under the name Transaction Systems Architects (TSA). Prior to that ACI had periods under US West and Tandem ownership and as a private company.

Today's ACI builds on more than 30 years of experience of delivering systems to process payments for banks, processors and retailers around the world. That experience is recognised in the high customer satisfaction ratings given by customers.
