Loyalty Reward Cards: How Every Loyalty Card Type Works

Jurgen Swaans

A loyalty reward card is the credential a retailer uses to recognise a returning customer and give them something back, such as points, stamps, a lower price or a personal offer, for what they buy. It can be a paper stamp card, a plastic card with a barcode, a digital card in an app, a pass in Apple Wallet or Google Wallet, or the payment card itself in a card-linked programme.
"Loyalty card", "reward card" and "loyalty reward card" all mean the same thing. What differs is the format, and the format decides how much you learn about your customers, how fast you can change the programme and what it costs to run.
In the UK, almost everyone already carries one. A survey by the National Centre for Social Research for the Competition and Markets Authority, published in November 2024, found that 97% of regular grocery shoppers are a member of at least one loyalty scheme, and that 40% do not trust that the loyalty price is a genuine saving (NatCen, Attitudes towards supermarket loyalty pricing). Getting a card into a shopper's pocket is not the hard part. Being worth using is.
What a loyalty reward card does at the till
Every loyalty reward card does three things, in this order.
It identifies the customer. The till reads a barcode, a QR code, a card number or a phone number and links the purchase to one member.
It applies a rule. Points per pound, a stamp per visit, a member price, a coupon, progress towards a tier.
It stores the transaction. That record is what lets you send the next offer to the right person instead of everyone.
Step one is where the format matters. A plastic card left in a drawer earns nothing; a card on the phone can also show a balance, an offer or progress towards a reward at the moment it is used. If you want the wider picture on programme design first, our guide on what a loyalty programme is covers the basics.
The five types of loyalty reward card
1. Paper and plastic stamp cards
The oldest format: a card stamped or punched at each visit, with a free item at the end. It costs almost nothing and needs no technology at the counter. But there is no customer identity behind it, cards get lost, and fraud is as easy as a borrowed stamp. The same mechanic works far better digitally: a digital stamp card can reward purchases, visits or other actions, show progress on screen and set different goals for different customer segments.
2. Barcode, QR and magnetic stripe cards
This is the classic plastic loyalty card: a number printed as a barcode (older cards also carry a magnetic stripe) that the till scans to link the basket to an account. Large UK programmes were built on it. Boots launched its Advantage Card in 1997 and reported more than 15 million active card holders in 2022 (Boots UK newsroom).
Plastic works without a phone or a signal, and the number can be typed in by hand when a barcode will not scan. Its weakness is everything after the scan: the card cannot show a balance, carry an offer or tell the customer what they are close to winning, and reissuing lost cards is a running cost.
3. Digital cards in an app
Here the card lives inside the retailer's app as a barcode or QR code on screen. It is now the default for the big UK grocers and health and beauty chains:
Tesco Clubcard. Customers get a digital Clubcard in the Tesco app, scan it at the checkout for Clubcard Prices, add coupons for use in store and online, check their points and turn points into vouchers (Tesco help: moving from plastic to a digital Clubcard).
Boots Advantage Card. Boots moved the Advantage Card into the Boots app in May 2019 (Boots UK newsroom).
Nectar. The Nectar app offers Your Nectar Prices, up to 10 personalised discounts per customer each week, activated in the app before shopping at Sainsbury's (Nectar app page). Our Nectar card analysis looks at that programme in more depth.
Lidl Plus. Shoppers scan the Lidl Plus app to collect points for a rewards marketplace and find personalised coupons in the app (Lidl GB).
Once the card is in an app, it stops being a key and becomes a channel: offers, coupons and personal prices travel with it. The cost is that customers have to download and keep the app, so it has to give them a reason to open it.
4. Apple Wallet and Google Wallet passes
A wallet pass puts the card in the phone's built-in wallet rather than in a separate app. On iPhone, customers add a pass by tapping "Add to Apple Wallet" in an app, email, message or web page (Apple Support). Google Wallet lets customers search for a loyalty programme in the app, scan an existing card or add a pass from the retailer's own app or site (Google Wallet Help).
Many retailers use the wallet as a companion to the app. Tesco lets customers add their Clubcard to Apple Wallet or Google Wallet from the app, so the card works even without a phone or Wi-Fi signal (Tesco help). Boots made the Advantage Card available in Apple Wallet and Google Pay in October 2019 (Boots UK newsroom).
A wallet pass removes the download barrier and is quick to scan, but it carries little more than a number, a balance and a short message. Games, challenges and a reward shop need an app or web experience.
5. Card-linked programmes
In a card-linked programme there is no separate loyalty card. The customer registers a debit or credit card once, and purchases with that card are rewarded automatically, with nothing extra to scan.
The trade-offs sit with the retailer. Cash and other cards fall outside the programme, you rely on payment partners for the data, and you lose the moment where a customer opens your app and sees an offer. That is why card-linked rewards tend to be an add-on to a card or app programme rather than the whole of it.
Physical vs digital loyalty reward cards compared
Physical card (paper or plastic) | Digital card (app or wallet pass) | |
|---|---|---|
Cost to issue | Printing, postage and replacing lost cards | No print cost; app or pass needs building and maintaining |
Works without a phone | Yes | No, though a wallet pass can work without signal |
Speed at the till | Fast when the card is to hand | Fast once the customer opens the card |
Customer identity | Only if the card is registered | Usually tied to an account from the start |
Personal offers | Sent through other channels | Shown on the card or in the app |
Gamification | Stamps printed on paper | Challenges, instant win, progress bars, games |
Changing the programme | New cards or leaflets | Update the rules and screens centrally |
Best fit | Customers who will not install an app, simple stamp schemes, a bridge during migration | Frequent shoppers, brands with an app or a plan for one |
Digital wins on almost every line that affects revenue, which is why the big UK programmes moved; plastic remains the fallback for customers who will not install another app. We compare the two in detail, including costs, in digital vs physical loyalty cards.
How retailers choose a loyalty card format
The right format follows from where you are today, not from what the biggest grocer did. Four questions settle most of it.
Do you already have an app that customers use? Then put the loyalty card inside it: the download barrier is gone, and loyalty gives people a reason to open the app more often. If you have no app, a standalone loyalty app or a web-based card is the realistic starting point.
Do you already run a card programme? Then the question is migration, not launch. Most retailers keep the plastic card valid while steering new members to digital. Tesco Central Europe showed one way to speed that up: shoppers in Hungary, Czechia and Slovakia received a physical scratch card with in-store purchases, and its unique QR code opened a digital scratch-card game in the Clubcard app. Run with MAGNEDS on NeoDay, the campaign generated over 2 million plays and more than 100,000 new app downloads in three months (case study).
What can your tills read? Check early if your POS can look up a member by card number and send the basket to the loyalty platform. That integration usually sets the timeline more than the card design does.
What do you want the card to do beyond points? If the plan includes personal offers, challenges or games, you need a screen the customer looks at, which means an app or web experience, with a wallet pass or plastic card as the quick way to scan.
Where NeoDay fits
NeoDay is a loyalty platform for retail, QSR, fuel and fashion chains, typically with 50 or more locations. It is not the right choice if you only sell online through Shopify, or if what you mainly need is a rules engine your own developers configure line by line (how NeoDay compares).
On cards specifically:
Digital membership cards. NeoDay's membership card software creates branded digital cards that show member details and loyalty status, scan as a QR code, barcode or alphanumeric code, redeem vouchers and coupons through a card scan, and connect to points, tiers, rewards and campaigns.
Physical cards still work. At the checkout a POS can identify a member by NeoDay user ID or by customer card number, scanned from the app or read from a physical loyalty card (developer docs: POS integration). That is what lets plastic and digital run side by side during a migration.
Three ways to put the card in front of customers. A standalone loyalty app that NeoDay builds and maintains, an SDK inside the app you already have, or a web-based programme that runs in any browser with no download.
Codes on physical touchpoints. UniQodes are unique QR or alphanumeric codes on packaging, receipts or in-store materials that customers scan to claim rewards or join campaigns.
A launch follows NeoDay's 10-week plan: design in weeks 1 to 3, build in weeks 4 to 7, launch in weeks 8 to 10, which is realistic when your POS and app partners are involved from day one. For the practical steps on the digital side, read our guide to setting up a digital membership card programme.
FAQ
What is a loyalty reward card?
A loyalty reward card is the credential a retailer uses to recognise a returning customer and reward their purchases with points, stamps, member prices or personal offers. It can be paper, plastic, a digital card in an app, an Apple Wallet or Google Wallet pass, or a registered payment card in a card-linked programme.
Are digital loyalty cards better than plastic ones?
For most retailers, yes. Digital cards cost nothing to print, are tied to a customer account, show offers and progress on screen and change without reissuing anything. Plastic still makes sense for customers who will not install an app, so many programmes run both for a while.
Is a loyalty card the same as a reward card?
Yes. "Loyalty card", "reward card", "loyalty reward card" and "membership card" describe the same thing, and the mechanics at the till are identical.
Can a loyalty card go in Apple Wallet or Google Wallet?
Yes, if the retailer offers a wallet pass. On iPhone, customers tap "Add to Apple Wallet" in the retailer's app, email or web page; in Google Wallet they can search for the programme, scan an existing card or save it from the retailer's app or site. Tesco, for example, lets customers add their Clubcard to either wallet from its app.
Can a retailer run plastic and digital loyalty cards at the same time?
Yes, and it is the usual way to migrate. The card number stays the same, so the till can identify a member from plastic or from the app. New members are steered to digital and existing members switch when they are ready.
What data does a loyalty reward card collect?
At minimum, who bought, when, where and how much. If your POS sends the basket, you also see which products were bought, which makes personal offers and category challenges possible. A digital card adds what happens in the app.
How long does it take to launch a digital loyalty card programme?
On NeoDay, a programme can go live in as little as 10 weeks: design in weeks 1 to 3, build in weeks 4 to 7 and launch in weeks 8 to 10. That is realistic when your POS and app partners are involved from day one.
