# Can staff add a stamp by scanning a customer’s card?

Yes. Open the staff app (Loyalty cards → Open the staff app) signed in as your shop, signed in as a team member, or on a device you paired in Team (under a team member, or as a shared device). Scan the QR code on the customer’s loyalty card and their card opens with an Add a stamp button. Each press adds one stamp.

The QR code is on the card in their wallet. On their phone’s card screen it is hidden until they press Show code to staff, which is also how you help a customer whose phone can’t save the card to a wallet.

Two coffees is two presses, and a stamp you add is instead of a tap, not as well as one. Anyone else, signed out or from another shop, sees the card only, never the button. On Pro and Premium, Team → Stamps by staff shows how many stamps each person and phone gave.

A reward saved in their wallet has its own QR code, which opens that reward with its Use button. Let the customer press it in front of you. See [how rewards work](https://thetap.shop/docs/loyalty-rewards).
