The French Supreme Court ruled that a scanned signature does not have the same reliability as an electronic signature. It held that a scanned signature could not be used to identify the person who signed it, or to prove his or her consent to the obligations arising from the deed. Apr 15, 2024

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.
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.
