Digital drink tickets: replacing paper tokens without new hardware
Paper drink tickets and plastic tokens get lost, copied and counted by hand. A digital drink ticket is a link with a balance – and the balance is what makes it work.
What a digital drink ticket is
A digital drink ticket is a link that opens on the guest’s phone and shows a QR code and the number of drinks left. Staff scan the QR; the number goes down. The important part is where the number lives: on a server, not in the picture of the QR code.
Why screenshots don’t break it
People worry that a QR code can be screenshotted and shared. It can – and it doesn’t matter, because every copy points to the same balance. Ten drinks are ten drinks, whether they’re scanned from one phone or five. What breaks systems is a ticket that “is” the drink, like paper; a balance on a server can’t be duplicated.
Handling the busy moments
- Accidental double scans. A good system asks before deducting again if the same ticket was just scanned a few seconds ago.
- Mistakes. Bartenders need an undo for the scan they did by mistake – briefly, so it can’t be abused later.
- Several bars at once. If two bartenders scan the last drink at the same instant, only one may succeed. That has to be enforced by the database, not by luck.
Who scans what
If you give both drinks and food, make sure the bar can only redeem drinks and the kitchen only food. Otherwise a food ticket becomes three beers at the end of the night.
Passing drinks on
A DJ with ten drinks wants to give two to a friend. With paper, that’s two tickets torn off. Digitally, the holder passes part of the balance on as a new link – and the organiser can still see where every drink went.
What it costs to start
You don’t need scanners: any staff phone with a camera and a browser can scan. You don’t need an app either, for guests or staff. What you need is a mobile connection at the bar, because the balance is checked live.
