Mobile signature

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