Electronic Signature Request

The solution includes strong authentication through the use of OTP (One Time Password), which help increase the security level of the signature and further protect the signed documents.This is because the phone number is associated with the signer and, thanks to the proof dossier, it allows linking a specific signer to the signing of a document.

It includes procedure data (id, creation date, sending and expiration), signer data (name, surname, email, phone number, IP address), and signer authentication methods (authentication method, message sent, and validation time)
The audit trail, as per regulations, is kept in original for 10 years.
The electronic signature has already been integrated for signing documents such as pre-contracts, quotes, sales or rental contracts, and general documents.
