Out of network connection
The user's personal data is stored directly in the buffer, allowing authentication and buffering without the need for a network connection.
Ultra-secure authentication
The stamp uses an innovative and patented optical and Bluetooth pairing and authentication technology. Coupled with the request of a confidential PIN code, it allows a strong authentication before launching the electronic signature procedure.
Guaranteed traceability
During buffering, the proof of signature is stored: on one side in the buffer memory instantly, and on the other side in a secure remote server after synchronization.
