Glass ID · alpha, for testers

Check a piece

Point your phone at it to see who made it. Load the piece's registered Glass ID, then take shots of the piece in front of you; the confidence rises as your angles line up with the ones on file. Nothing you shoot leaves this device. A likely match means this is the registered piece. It is strong evidence, not proof. Alpha: the thresholds are still being tuned with testers' help.

A Glass ID is a fingerprint of the glass itself, stored as numbers, not photos.
