Schools: credentials you can actually revoke.
Schools need identity credentials. They do not need a badge system that costs more than the yearbook. Watermelon Auth gives students and staff a card that verifies on any phone, and gives the school the ability to kill a lost card on the spot.
Student IDs
A student card is a secure NFC credential. Tap it with a compatible phone and the school's verification page shows the record, the holder, and current status.
Staff credentials
The same platform issues staff IDs, substitute badges, and temporary passes. Each one has its own lifecycle. Each one can be revoked alone.
Event passes
Dance tickets, game passes, conference credentials. They verify live, and a revoked pass stops verifying the moment it is revoked.
Homeschool and small associations
Real cryptographic credentials without buying infrastructure. One platform, many issuers, no vendor lock-in.
No readers, no proprietary hardware
Verification runs on phones and a server you control. The kids already carry the readers.
Lost cards are a non-event
Revoke it, reissue a replacement, done. The old credential stops working immediately.
