Unique ID

Unique ID turns your phone into an ID card for access control, time and attendance
and event check-in systems built with Digital Logic hardware.

Hold the phone near a uFR Zero reader and the reader reads it like a card. Most phones have
a random NFC ID that cannot be used for identification, so this app gives your phone a
stable Unique ID and sends it over NFC.

THREE CARDS, ONE APP

ID Card
A simple ID. Sign in with Google and it comes from your Google account, so it stays the
same on any phone. Without signing in, it belongs to this phone.

Secure Card
A safer ID. It uses a secret key kept in the phone's secure hardware, so it cannot be
copied. The reader checks the key on every read.

SecureMax Card
The safest ID. Confirm with your fingerprint or face, and the card works for the next
seven seconds. The key is bound to your biometrics.

THE READER CHOOSES

You do not pick a card in the app. The reader asks for the card it is set to, and the
card that was read shows a check mark.

- Press and hold a card to copy its ID
