Here's the whole thing.
It takes a minute or two.

Somebody has a lovely time and posts about it.
Instagram, TikTok, a Story gone by lunchtime. Then nothing. You can't use it, they never hear from you, nobody wrote it down.
They scan the card on your table, mirror, door, or counter.
Your offer, your rules, plain language. Your customers paste a link or upload a screenshot. No app, no account, no queue.
We ask if you can use it. In writing.
Nicer than sliding into their DMs three days later. Sharing it and advertising with it are two different favours, so they answer both.
Code lands straight away. No waiting about.
One code, one person, one time. And if they pass one to a friend, that gets its own code, so you'll see who sent who.
Somebody checks the code. Green means yes.
One PIN-locked screen tells them exactly what to hand over. One tap. That's the training. And that's the second visit, paid for by the first.
Nothing gets through unchecked.
The obvious ones clear in seconds. Anything odd, a recycled photo, a brand new account, is held back and waits for one of us to look properly.
