Documents: paper that verifies itself.
Paper certificates and licenses get copied, scanned, and forged every day. Watermelon Auth puts a cryptographic credential on the document itself, so the paper verifies.
Certificates
A secure NFC tag on the certificate links it to the issuer's verified record. Tap the paper, see the record.
Licenses and permits
A physical license with live status. Tap it to confirm it is current, or revoked.
Records and seals
Physical seals cryptographically bound to their record. Tamper with the paper and the record no longer matches.
Anti-forgery
A scan, photocopy, or photograph cannot produce a fresh tap response. The document's credential proves presence.
No readers needed
Any compatible phone taps and verifies. No special hardware for the person checking the document.
Lifecycle
Issue, verify, replace, revoke, audit. The same managed credential lifecycle as every other physical thing.
