Key features:
- Remote user authentication with one-time password or challenge/response;
- E-signature capabilities for securing and verifying on-line transactions;
- Compatible with all Digipass models and server tools;
- Multiple profile support;
- Integrated in Digipass Pack.

All Digipass models are interoperable. We foresee that more and more companies all over the world will combine the use of Digipass hardware tokens, the server based Digipass Authentication Server and Digipass for Windows 4.0 in one and the same system, depending on the needs of the end user.”
