CryptoAuthentication memory tokens are ideal for...

User Rights / Preferences / Settings

When used in identification applications, Datakey CryptoAuthentication memory tokens not only identify the user, they can also store the user’s preferred settings for that machine, allowing every machine that a user works on to be configured automatically to his/her personalized settings. The memory tokens can also store rights information, only allowing users access to the functions they have been trained on.

Feature Enable

Datakey CryptoAuthentication memory tokens make it easy for users to purchase a base model of a product and later upgrade it by enabling additional functionality, all using the same hardware. Manufacturers can ship products with all features built in, but only enable those features that customers pay for. Additional features can be enabled after the product has been deployed by simply providing a secure feature-activation token.
