How a loyalty card on your phone works
A loyalty card on your phone, also called a digital loyalty card, replaces the paper card with a card saved on the customer's phone, iPhone or Android. Customers get it by scanning a QR code or tapping their phone on an NFC sticker, without installing an app. With each purchase, the merchant scans the card, points are added, and the card updates itself on the customer's phone.
That is what Wafly does for cafés, restaurants, bakeries, salons and shops in Algeria.
