The H-Token Geronimo looks deceivingly simple, just like any standard USB device. Under its hood, however, this token is packed with powerful electronics and components, making it one of the most versatile and powerful security devices in the market. The internal smart card is secured against DPA/SPA attacks and supports encrypting the H-Token Middleware channel used by the applications accessing the device.

The H-Token Geronimo allows storing data on its multi-partitioned flash in CD-ROM, Read-Only, Read-Write, Encrypted or Hidden (raw access) mode. When required, this token can be also used a SSCD device for legally binding, non-repudiation tasks.
