How to Set Up a QR Code Loyalty Programme

How a QR Code Loyalty Programme Works

A QR code loyalty programme uses QR codes for two jobs. The first is enrolment: the customer scans a printed code, taps Add to Apple Wallet or Add to Google Wallet, and the card is on their phone. The second is stamping: at each qualifying purchase, staff scan the customer's pass, or the customer scans a code at the till, and the stamp is recorded.

The appeal for a small business is that it needs almost no equipment. You need a printed QR code and a phone or tablet the team already has. There is nothing to install on the till, and no card stock to print and replace. The wallet mechanics are covered in our guides to Apple Wallet loyalty cards and Google Wallet loyalty cards.

Step 1 - Choose the Objective and the Reward

Decide what behaviour you want to change before you touch a QR code. More visits from regulars? Higher spend per visit? Fewer lapsed customers? The answer shapes the reward.

For most independents, a simple stamp card is the right start: buy a set number, get a reward. Set the target so that a regular reaches it in a few weeks - roughly six to ten stamps for a café, four to six for a service with a longer visit cycle - and cost the reward at what it costs you to give, not the shelf price. Our guide to stamp cards vs points helps you choose the mechanic, and the loyalty programme ROI article shows how to test the maths.

Step 2 - Design a Sign-Up That Takes Seconds

The shorter the journey, the more customers finish it. Aim for: scan, tap Add to Wallet, done. Every extra form field costs sign-ups.

Ask for the minimum. A first name is enough for a friendly card; only ask for an email address or phone number if you have a clear use for it and can explain that use at sign-up. If you will send marketing messages, make consent clear and separate - see our UK GDPR and PECR guide.

Test the journey on an iPhone and an Android phone, on mobile data as well as Wi-Fi, and with someone who has never seen it before.

• One screen, one button: Add to Apple Wallet or Add to Google Wallet
• Ask for the minimum data and say why
• Keep marketing consent separate from joining the programme
• Test on both iPhone and Android before you print anything

Step 3 - Place the QR Code Where Customers Will Scan It

A QR code that nobody sees does not work. Put it where customers are already waiting or paying, and add a short line that says what they get: 'Scan for a free coffee after 9 stamps'.

Use more than one placement, because different customers notice different places. Make the printed code large enough to scan from a comfortable distance, keep the contrast high and avoid placing it behind glass with reflections or on a curved surface.

• Counter or till: the highest-traffic spot; use a stand at eye level
• Table cards and menus: for sit-in cafés and restaurants
• Receipts and bags: reaches customers after they leave
• Booking confirmations: ideal for salons and studios
• Window or door: turns passers-by into first-time visitors
• Cup sleeves or packaging: for takeaway-heavy coffee shops

Step 4 - Train the Team to Stamp Fast and Offer the Card

Your staff are the sign-up engine. A programme that depends on customers spotting a sign will grow slowly; one where staff say a single sentence at the till grows quickly.

Give the team a one-line script ('Do you have our loyalty card? It takes ten seconds and sits in your phone') and a simple rule for what earns a stamp. Rehearse the stamp flow until it takes two to three seconds, so it never slows the queue. Decide who can issue reward redemptions and what to do if a customer's phone battery is dead.

• Agree what counts as a qualifying purchase and write it down
• Practise stamping during a quiet period before launch day
• Give staff a one-line script for offering the card
• Decide the process for redemptions and lost or replaced phones

Step 5 - Put Fraud Controls in Place

Any stamp scheme can be misused: staff stamping their own cards, customers sharing a card or a screenshot of a QR code being reused. Controls should make abuse hard and visible without adding friction for honest customers.

Look for a platform that ties stamps to a specific card, limits how quickly stamps can be issued, logs which staff member issued each stamp and lets you review activity. No control is absolute, so describe them as reducing risk rather than eliminating it, and review unusual patterns regularly. Ruloyal's features page lists the fraud controls included in each plan.

• Stamps tied to an individual card, not a shared code
• A time limit between stamps for the same card
• A log showing which staff account issued each stamp
• A regular review of unusual patterns, such as many stamps at closing time

Step 6 - Launch, Measure and Improve

Launch with a small push: tell your existing regulars in person, post the QR code on social media and consider a first-stamp incentive. Then track a few numbers for the first 90 days: how many customers joined, how many earned a second stamp, how many redeemed a reward and how many have not visited for a month.

Those four numbers tell you whether the reward is right, whether the signage is working and whether you need a reminder for lapsing customers. Our guide to loyalty programme KPIs explains how to define and read each one.
