Carreker Corporation Press Release - August 22, 2002

CARREKER’S CASH TECHNOLOGY EXPANDS INTO AUSTRALIA AND NEW ZEALAND

DALLAS (August 22, 2002) — Carreker Corporation (Nasdaq: CANI ), a leading supplier of technology and consulting solutions for the financial industry, today announced it has signed agreements with leading financial institutions in Australia and New Zealand to implement its Integrated Cash Operations Modules™ (iCom) solution. ASB Bank, Bank of New Zealand and one of the large Australian banks will use Carreker’s Internet-enabled cash inventory management solution to aid in the management of their cash inventories.

iCom uses demand-based inventory management techniques to identify a daily cash activity profile for each cash point. The technology determines the optimal inventory, order, and shipment amounts for cash at individual branches, ATMs, transportation providers, and vaults. It interprets and imitates historical cash usage data to define customer behavior and adjusts for variables to forecast future customer demand. In addition, iCom provides multiple levels of customized alerts to prevent cash outage situations.

“Banks are challenged to know how much cash needs to be available for withdrawals at every cash point," said Brian Evetts, Carreker's Managing Director of Cash and Logistics solutions. "The goal is to achieve the right balance of cash available for withdrawals - taking into account the demand fluctuations for locations, the time of day and days of the week – and cash available for investing in other areas."

“We are pleased to expand our services used by banks in these markets,” John Carreker, Carreker Corporation’s Executive Vice President and Managing Director International, said. “Banks in the Australasian region have responded impressively to new regulations in cash handling. This proves that the banks have confidence that our products will help them with these processes."

"It's a great opportunity to drive further efficiencies in our cash group, while at the same time continuing to deliver improvements in customer service." said Robyn Cocks, National Manager Cash of Bank of New Zealand — a division of National Australia Bank. "iCom will also assist us in the development of new cash services and procedures."

“We pride ourselves on providing the best customer service and using technology to improve our profitability and processes,” Peter Meehan, Chief Manager Personal Banking Operations of ASB, said. “Improving our cash management processes will optimize security by leaving less cash in branches and reduce our overall operating costs.”
