Choose the certificate's signing role
Thai Digital ID distinguishes three document-signing certificate types. A Personal certificate identifies an individual, with examples including contracts, quotations and purchase orders. An Enterprise certificate identifies the legal entity issuing a document. An Enterprise User certificate identifies an officer acting in the context of that organization.
These choices answer different questions about an approval: who signed personally, which organization issued the document, or which officer acted for the organization. Selecting the right subject is therefore part of preparing a TDID digital signature.
Prepare a document-signing credential
TDID describes its certificates as X.509 records containing identity information and a public key. Obtain the certificate appropriate to your intended signing role through the provider's application process, and have the corresponding signing access ready before completing a Nota Sign request.
The Thai Digital ID website explains the certificate categories and their intended uses. For an enterprise workflow, establish whether the document needs an organization's credential or an individual officer's credential. That choice should match the identity expected in the signing request.
TDID also issues TLS/SSL certificates for websites and servers. Those credentials secure connections; a website certificate is not a substitute for the document-signing certificate required here.
Sign or seal with TDID in Nota Sign
Nota Sign supports TDID digital signatures and organizational electronic seals. Review the document, enter the required information and proceed with the configured TDID method. Use the credential that matches the requested person or organization, complete the authorization required for it and finish the document workflow in Nota Sign.
For a personal approval, the signature relates to the individual certificate holder. An organizational seal instead identifies the issuing organization. A staff member's personal signature and the organization's seal remain distinct even when both concern the same business document.
