OAKBROOK TERRACE, Ill., and BRUSSELS, Belgium, August 21, 2006- VASCO Data Security International, Inc. (Nasdaq: VDSI) (www.vasco.com), the global number one vendor of strong user authentication and e-signature products, today announced the Swiss financial institute PostFinance (www.postfinance.ch) will start deploying Digipass 810 to its e-banking clients in the spring of 2007.

PostFinance is the financial services arm of Swiss Post. The last few years, PostFinance has developed into an all-round retail financial institution. With more than 720,000 online clients, its e-banking system E-Finance-yellownet is the largest financial services provider in Switzerland.

To add an extra layer of security to its successful banking channels, PostFinance opted for VASCO’s Digipass 810. The functionalities of Digipass 810 include EMV-CAP (Europay-Mastercard-Visa Chip Authentication Program), which makes PostFinance the first financial institute in Switzerland to use strong authentication that is EMV-CAP certified.

VASCO’s Digipass 810 offers the advantage of a great range of personalization possibilities.”
