Euronet Stet Hellas Announce Agreement to Offer Mobile Banking in Greece LEAWOOD, KANSAS USA AND ATHENS, GREECE (February 1, 2001) — Euronet Worldwide, a leading provider of secure financial transaction solutions and (Nasdaq: EEFT) and Stet Hellas Telecommunications S.A. (Nasdaq: STHLY; Amsterdam: STHLS), Greek mobile operator today announced an agreement to jointly offer mobile banking solutions to financial institutions in Greece.

Targeting financial institutions such as banks, credit unions, brokerages and mutual fund companies, Stet Hellas and Euronet will offer Short Message System (SMS) and Wireless Access Protocol (WAP) based account access and event messaging services. These services are offered as a wireless Application Service Provider (ASP) solution.

These new services are immediately available to financial institutions and can be quickly operational. Using their mobile phone, customers will be able to conduct secure, real-time transactions and access personal account information. Once deployed, bank customers can establish and maintain alerts to track their personal accounts and portfolios.

Mobile account access provides customers the ability to make balance inquiries, retrieve mini-statements, perform intra-bank transfers, change passwords, report lost or stolen debit cards and add or delete alerts right from the palm of the hand.

The mobile SMS-based event messaging capability is driven by the individual customer’s preferences. Once activated, the program automatically notifies the customer via their mobile phone with invaluable information such as account balances, confirmation of deposits, withdrawals, POS debits, credit card transactions, the fact that a loan payment is due or an account has reached a pre-established balance.
