Visa and MasterCard are now Accepted at Euronet ATMs in the UK HERTFORDSHIRE, UK AND LEAWOOD, KANSAS, USA—September 4, 2002—Euronet Worldwide (NASDAQ:EEFT), a leading provider of secure electronic financial transaction solutions, today announced that Euronet's UK operation now offers Visa and MasterCard acceptance on Euronet ATMs for cash withdrawals and credit card cash advances after successfully completing a rigorous Visa audit of processing security and general procedures. Citibank International, plc is sponsoring Euronet in this UK initiative.

"By adding international card capabilities like Visa and MasterCard at Euronet ATMs in the UK, we instantly have a wider customer base, including international travelers," said Ron Delnevo, Euronet Worldwide managing director, UK office. "We have already seen transactions on our ATMs increase by 3% upon the launch of this service, and expect the increase to reach 5% over the next year in the UK as the service becomes better known. Our ability to quickly pass these strenuous audits is a testament to the processing infrastructure that Euronet has created, and we believe that UK banks will see the value of our product offering depth as more organizations consider the transition to outsourcing."

Euronet is currently partnered with Citishare and Citibank in six countries, including the ATM outsourcing program for Citibank Greece. "Citishare and Citibank have a high degree of confidence in Euronet's ability to provide secure and stable processing services, and we're pleased to work with Euronet in the UK market," said Matthew Lanford, Citishare vice president global client services.

"Already Citibank customers are seeing tangible benefits from this partnership. Citibank's UK customers can now access over 740 ATM's nationwide with their Visa or MasterCard and pay no surcharge. This is yet another example of how Citibank is delivering premium banking to the UK consumer," added Sanjeeb Chaudhuri, group managing director, Global Consumer Bank.
