What does a check prove?

SHA-256 proves file equality only. Email OTP indicates control of an email address, not legal identity. Audit records are held within ThaiPDF, without an independent external anchor. This is not government or independent CA certification, or a universal PDF validator.

Why upload a file if I have an ID?

An ID or QR looks up a record. It cannot tell whether the PDF you hold matches that record. Upload your PDF to check its actual bytes, without signing in.
