Guests tap. You host.
A passive NFC tap point. No power, no Wi-Fi, no app for guests. It sticks to a wall with the adhesive in the box, sits flat on a table, or stays in a host’s hand at the door.
Stop working the door.
Manual check-in works. The Block just changes whose hands do it. Instead of you logging each arrival, the guest taps a fixed point on the way in, and you get to host the room.
