SignDoc is an enterprise level solution that provides clear proof of who signed (signatory), what they signed (content status of a document at time of signing), and when they signed (date and time). SignDoc goes beyond electronic signing of a document package by providing digital signatures for each, single signature included in a package. Signing triggered by handwritten signatures may include capture of biometric signals of the writing process according to the ISO/IEC 19794-7 standard.
Captured photos of signers and/or signer IDs may be added to document as ISO/IEC 32000-1 PDF standard compliant digital signatures. SignDoc verifies transactional integrity with easy access to both document and process audit trails, without the cost and headache of maintaining additional software.
All you need is a PDF reader. Document validation is independent of connection to external services, so there is no vendor lock-in.
