Authenticate and sign documents on smartphone or tablet

With the electronic stamp, it’s possible to authenticate and validate a stage directly on smartphone and tablet, in a few seconds.

Offline network connection

Personal user data is stored directly in the stamp, allowing authentication without the need for a network connection.

For better traceability

During buffering, a double proof is stored: on the one hand in the buffered device, and on the other in the memory of the electronic buffer, then in blockchain.

Ultra secure authentication

The stamp uses innovative and patented pairing technology, based on the management of unique encrypted tokens for each stamping.

There are 3 authentication factors: the stamp, a PIN code and facial recognition. It is possible to choose your security level with the formula that best suits you. Discover our plans.
