How it works, at one table.
Nothing for guests to install and nothing for you to connect. A printed QR and your phone do all of it.
1They scan the QR
It opens in the camera. No app, no account.
2They tell you how it was
A few questions, in your words and their language.
3They come back
Staff scan their thank-you at the till. That's your count.
