Digipass GO3 is a lightweight, low cost strong user authentication token, especially designed for the large volume retail banking market. GO3 is extremely easy to use. With a simple touch of a button, the end user generates a unique one-time password. Digipass GO3 is VASCO’s answer to banks that want to give their retail customers a simple though secure means to use Internet banking applications. GO3 is the secure, cost effective and user-friendly alternative for systems such as TAN-lists (printed lists of transaction numbers). Banks don’t need to invest time and money in sending TAN lists to customers. In addition, banks using GO3 eliminate the security risk of their customers entering a static PIN code on the Internet to get access to the bank’s system.

Important features of Digipass GO3:
·Small and lightweight;
·Extremely easy to use;
·Compatible with the 15 other members of the Digipass family in the same application;
·Cost effective and reliable investment with an expected lifespan of over 5 years.

“Digipass GO3 complements our Digipass family,” said Jan Valcke, VASCO’s President and COO. “VASCO has developed Digipass models for several markets and numerous applications. Digipass GO3 is our answer to the retail-banking market, a market that desperately needs flexible and easy to use strong authentication products, at a reasonable price. It is our firm belief that Digipass GO3 is THE cost effective alternative for insecure TAN-lists and online use of static password systems.”
