Mobile signature

Mobile signature refers to the ability to electronically sign a document from a smartphone or tablet, without a native application — via the web browser. The signer receives a link via email or SMS, views the document in their mobile browser, initials and signs with a tap gesture or by typing their full name (depending on required level), then validates via SMS OTP. On Certyneo, the signature interface is 100% responsive: identity verified, audit trail generated, and co-signed PDF delivered to the recipient in under 60 seconds on 4G mobile. No installation required for the signer.
