avec QR code : la mettre en place dans votre commerce loyalty card

By the FidèlPro team · Updated on · 6 min read

The QR code has become second nature: restaurant menus, payments, tickets. It's also the simplest way to get your customers into a loyalty programme. You still need to know where to place it, how to validate visits and how to prevent abuse. Here's a proven method, adapted to local shops.

Two QR codes, two different roles

A modern loyalty programme usually involves two QR codes:

  • The sign-up QR code, displayed in the shop: the customer scans it once to create their card.
  • The card's QR code, displayed on the customer's phone: the merchant scans it at each visit to add a stamp or validate a reward.

Keeping the two clearly apart avoids confusion at the till. The first is for recruiting, the second for retaining.

Where to place the sign-up QR code

  • Next to the payment terminal: that's where customers have their phone in hand and a few seconds to wait.
  • On a counter stand, at eye level, with a clear message: “Your loyalty card in 10 seconds, no app needed”.
  • In the window, for passers-by: a sticker is enough.
  • On your tables if you're a restaurant or café, next to the menu.

Avoid QR codes that are too small (under 3 cm per side), placed too high or behind glass that reflects light.

Validate visits without cheating

The weak point of many programmes is validation. If customers can add a stamp themselves by scanning a fixed QR code, cheating becomes easy: one photo of the QR code and that's it.

Best practices:

  • The merchant validates: by scanning the customer's card, or by giving them a code that changes regularly.
  • Only one stamp per day per customer, to prevent abuse.
  • Rewards with a single-use code, which the merchant checks when handing them over.

FidèlPro combines these three safeguards: scanning at the till, a daily code that changes every 5 hours, and single-use prizes.

The right message to encourage scanning

A QR code alone isn't enough: people need a reason to scan it. The messages that work best are concrete and immediate:

  • “1 free coffee after 10 visits”
  • “Your first stamp free when you sign up”
  • “No app, in 10 seconds”

Above all, say it out loud: a simple “Do you have your loyalty card?” at the till boosts sign-ups far more than any poster.

Common mistakes

  • A QR code that leads to a slow page or asks to download an app: the customer gives up.
  • A form that's too long: first name and phone are enough to get started.
  • Forgetting consent: marketing messages require the customer's explicit consent (see our guide loyalty cards and GDPR).
  • Not testing it yourself: scan your QR code with an iPhone and an Android before displaying it.

Printable kit: poster, table tent and sticker

To get started fast, prepare three materials: an A4 poster near the till, a counter stand and a window sticker. FidèlPro generates them automatically in your colours, with your QR code, ready to print.
