1. Digital Loyalty Card

A QR code in the supermarket's app or on a printed card represents the loyalty account. Scanning at the checkout credits points without a physical swipe card.

2. Points Voucher Redemption

A QR on a points voucher (printed or emailed) is scanned at the checkout to redeem its value. Unique, single-use tokens prevent duplication.

3. Personalised Offers

A QR in the weekly offers email links to a page of personalised offers based on purchase history: favourite brands, frequently bought products, and category preferences.

4. Staff and Admin QR

Behind the scenes, managers scan inventory QRs at markdowns and use store QRs at self-checkout lanes. The same technology serves multiple functions across the operation.

Frequently Asked Questions

How do supermarkets prevent a loyalty QR from being shared between people?

Loyalty accounts are tied to a registered email or phone number. Points are credited to the account; sharing the QR shares the points, which is usually allowed within household terms.

Can personalised offers be shown immediately after scanning at checkout?

Some systems display offers on a receipt QR after purchase. Real-time offers are more commonly delivered by email or notification after the scan event.
