Gatetally: The QR Check-In That Checks the Check-In

Field notes

The system uses a door-mounted sticker or tablet as the check-in surface, with the visitor's phone handling registration and SMS verification. The page describes a priority order in which memberships, ten-visit cards, and then payment determine what happens at the door. Its security distinction is concrete: codes carry a server-checked signature, while a photographed printed code may still require location checking to prevent off-site use.
