Check in without a screen, a phone, or Wi-Fi.
The Block is a passive NFC wall-mount. Guests tap their phone on arrival. Circuit records the attendance. No app required on either side.
Replace the door list with a wall mount.
Today, an organiser stands at the door with a phone and checks guests in one at a time. The Block moves check-in to a fixed point in the room. Guests arrive and tap. The organiser is free to host.

Ticketing tells you who bought a ticket. Not who came back.
Every ticketing platform structures data around the promoter, not the venue. The Block gives you one layer. One device per room, every organiser, every format, one record.
