Kiosk mode: let customers stamp themselves
A tablet at the counter shows a QR code that changes. Your customers scan it and take their own stamp, within the limits you set.

Kiosk mode is part of the Growth and Multi-site plans. A tablet (or an old phone) stands at the counter and shows a QR code that renews itself. The customer scans it with their own phone and touches one button: the stamp lands on their card. Nobody on your team has to do anything.
How it works for your customer
- They scan the code on the tablet with their phone's camera. No app to install.
- Their phone is recognised, and the page says hello. They touch "Take my stamp". Opening the page never stamps by itself.
- The stamp is added, the card in their Wallet updates, and the tablet plays a short "stamp received" animation. It never shows a name.
- A new customer signs up first and gets the one sign-up stamp. Nothing more that day.
Switch it on
- Open My card → Kiosk (owner only).
- Choose your limits: stamps per customer per day, the delay between two stamps, and how long a QR code lives. Examples are offered for a coffee shop, a bakery, a bar, a restaurant or a hairdresser; they only fill the form, you decide.
- Press "Switch the kiosk on".
- On the tablet, use "Open the kiosk on this device" if you are signed in there, or "Link another tablet": it gives you a link and a QR code to open on the tablet. The link works once and expires after 15 minutes. You never type your password on the tablet.
The limits are yours
- Stamps per day: for one customer, from 1 to 20. A bar and a hairdresser do not need the same number.
- Delay between two stamps: it counts every stamp of the customer, including the ones your team gives at the till.
- Life of the QR code: it renews itself, and as soon as it has been used once. A photo of the screen sent to a friend does not work.
What waits for your validation
- A stamp taken outside your opening hours.
- A stamp from a phone that has just been recognised by an e-mail code (a new phone).
- A stamp that comes very close to the previous one.
These stamps appear in your validations and your phone is alerted. A tablet can be removed at any time from the same page: its screen stops at once. The poster and the sign-up link never change: one stamp at sign-up, nothing after.
The kiosk shows that the customer was in front of your screen a few seconds ago, not that they bought something. Ask customers to scan after they have paid.
