Stamp cards

Use the staff app

Scan cards, add stamps and hand out rewards from the Zimtig app on iPhone, iPad or Android.

For:OwnersAdministratorsStaff2 min readReviewed October 2026

The Zimtig app is for serving stamp-card customers at the counter: find the customer, scan their QR code, add stamps and hand out rewards. It's one app for every restaurant, on iPhone and iPad (iOS 18 or later) and Android (8.0 or later).

Sign in

  1. Tap the sign-in button

    On Android it says Sign in; on iPhone and iPad, Sign in with WorkOS. Your browser opens.

  2. Sign in with your usual account

    Use the same email you use for your restaurant's dashboard.

  3. Compare the code

    The app shows a Verification code. Check that your browser shows the same one.

  4. Go back to the app

    If you work at more than one restaurant, choose which one to work with. You can change later with Switch restaurant.

Serve a customer

  • Search by name, email or code, or scan their QR code with the camera. If the camera fails, read the QR code from a photo or type the code.
  • Add a stamp: on their card, enter the Purchase reference, turn on This purchase belongs to this customer and confirm the stamp.
  • Hand out a reward: tap Redeem reward, then Confirm redemption.
  • Correct the last stamp, if your role allows it. In the Android app, only the Owner can correct.
  • Invite customers with your restaurant's QR code: on iPhone and iPad, open the Account menu and tap Customer QR; on Android, open the Invite tab.

The rules are the same as in the dashboard: looking up a card doesn't add stamps, and each reference earns one stamp per program. More in stamp purchases and hand out rewards.

If an action is left unconfirmed

If you lose signal while confirming a stamp or redemption, the app keeps it and shows a notice that it's unconfirmed. When you're back online, tap Check result: the app resends exactly the same thing and never records it twice. The notice stays even if you close the app or sign out. Resolve it before recording anything else.

What happens in the web dashboard

The app is for serving customers. In the web dashboard you create and configure programs and their invitation links, invite your team, and manage orders, the menu and restaurant details. The app doesn't save cards to Apple Wallet or Google Wallet either: each customer does that from their own card.

Frequently asked questions

Do I need a separate account for the app?

No. You sign in with your dashboard account, and your role decides what you can do.

The app says I don't have a restaurant assigned.

Ask an Owner or Administrator to invite you from Team, then sign in with the email the invitation went to.

Can I use the app offline?

No. Searching for customers, adding stamps and redeeming all need a connection. If it drops mid-action, the action stays unconfirmed until you're back online.
