The gap between liking a place and following it is about thirty seconds of typing a handle you half-remember, and most people never cross it. Plaque One closes that gap to a single tap at the till.

It sits on a counter, a table, a reception desk. A customer taps their phone to it — or scans the code — and your profile opens. iPhone and Android, no app needed, nothing for your staff to say.

Behind it, a small dashboard tells you how many taps you got today and which plaque they came from, so you know the till gets more taps than table twelve.

Change what it points to any time. Point it at Instagram this month and your Google Reviews page next month; the plaque doesn't change.
