Sign contracts with Mexican customers, suppliers and employees from any place and device, with a digital handwritten signature or an advanced electronic signature such as the e.firma, the advanced electronic signature issued by Mexico's tax authority (SAT). Every document gets biometric identity checks, a trusted timestamp and a NOM-151 certificate. NOM-151 is the Mexican standard for preserving data messages: the certificate proves integrity and date.
Choose the signature level by risk, document type and the legal framework that applies. ZIGN combines digital handwritten, simple electronic and advanced electronic signatures with NOM-151 in a single flow.
Captures the signer's stroke with coordinates, pressure and behavioral biometrics. Best for internal documents with low legal risk.

Mexico's Commercial Code (Código de Comercio) recognizes electronic signatures and data messages. Through NOM-151-SCFI-2016, Mexico's Ministry of Economy sets the criteria for preserving data messages when documents are signed electronically. Accredited certification service providers (PSCs) provide data message preservation and digitization in an audited process.
