QR on the table, a tap when you have the card

A QR code works across a table and on a slide. It fails when the room is dark or the other person doesn’t want to open the camera.

A physical NFC card works in a handshake and fails when you forgot it. NexShare keeps the digital card as the thing both of them open, and treats the code and the tap as doors into the same page.

In this build, NFC is a local request — nothing is manufactured — and the QR code is real. Scan it and the card records the visit.
