Do guests need to install anything to use the card?

No. The guest scans the QR code with the phone camera and the card opens in the browser. Nothing is installed and no sign-up is needed. If they want, they can add the card to the home screen so it opens like an app.

Does the card work without an internet connection?

Yes, in part. The guest’s card shows the last known state when the phone is offline. At the counter, stamps given without internet are queued on the device and uploaded automatically when the connection returns, so none are lost.

What personal data does the card store?

None. The card holds only a random identifier and the stamps. An optional guest account with an e-mail address keeps cards across phones, but the business cannot see that e-mail address.

Can guests still receive messages without an app?

Yes. Campaign messages appear on the card as a message for seven days. Guests who switch on browser notifications also receive them as a phone notification, and they can turn notifications off at any time.

Why we built our stamp card without an app

Stampback is a digital stamp card that opens in the phone’s browser straight from a QR code, so guests collect stamps without downloading an app, creating an account or sharing personal data.

Why guests don’t need to download an app for our loyalty card: the thinking behind the decision, what guests, staff and owners gain, and what we gave up.
