Questions
Do signers need to sign up?
No. Signers open the link in their e-mail, confirm it with a six-digit code, agree to sign electronically, then draw, type or upload their signature.
How is E-Sign workflow different from adding a signature to a PDF?
The signature tool in the PDF editor places your own signature on a document. E-Sign workflow sends a document to other people to sign, tracks their progress and keeps a record of events as evidence.
Is this a digital signature?
The signers' signatures are electronic signatures confirmed by e-mail. The completed document is sealed with ThaiPDF's digital (PKI) certificate, so any change after sealing can be detected. The certificate is issued by ThaiPDF itself, so some PDF readers may show the signature's validity as unknown; check it on the verification page. The evidence report is not a government certification.
How can I check that a signed PDF hasn't been changed?
Upload the file on E-Sign workflow's verification page. It compares the file's SHA-256 with the recorded one and tells you whether they match.
