Legally binding electronic signature

The electronic signature has legal validity in practically every country and regions in the world, for instance US, EU and Latin America.

ZapSign captures various signer authentication data in addition to the on-screen signature, such as the signer's IP, date and time, phone, email, unique code and device, browser, and operating system information. In addition, the integrity of the document is ensured by the SHA256 algorithm, a cryptographic hash function created by the NSA, which identifies if any type of change is made to the original document, in addition to the final document being digitally certified by ZapSign with an A1 ICP certificate.

The electronic signature of online documents can be used in practically all private documents such as contracts, powers of attorney (common and judicial), proposals, agreements, loans and registrations, among others.
