Card-Linked Offers: How They Work and How Brand-Funded Offers Reach Shoppers at Payment
How card-linked offers work, where they fall short for FMCG brands, and how brand-funded offers can reach shoppers on the card machine at payment.
Key takeaways
- Card-linked offers reward a shopper after an enrolled card is used at a participating merchant, and most programmes match at merchant level once the transaction has cleared.
- Offers on card machines reach the shopper during payment, with no app download, on supported card machines supplied by partner payment providers.
- Brands should judge either channel on the same criteria: reach in the stores that matter, attribution quality, match granularity, consent, and the reporting a campaign actually returns.
- The two channels can run together. One buys reach across issuers, the other buys presence at the moment of payment.
What are card-linked offers?
A card-linked offer is a reward attached to a payment card rather than to a coupon, a code or a loyalty card. The shopper activates the offer, usually inside a banking app or a publisher app, and the reward is applied when that enrolled card is used at the participating merchant.
Three routes dominate. Bank and card-issuer offer programmes surface offers inside the app the shopper already opens to check a balance. Card scheme programmes run similar mechanics across a wider issuer base. Card-linked APIs sit underneath both, letting publishers, affiliate networks and cashback apps enrol cards and receive matched transaction events without building issuer connections themselves.
Funding sits with the merchant or the brand, and it is almost always paid on performance. A merchant-funded cashback offer discounts the shopper's basket to drive footfall or win a switcher. Brand-funded offers do the same job for a manufacturer that has no direct relationship with the store's customers and no way to reach them at the moment they choose between two products on a shelf. The offer costs nothing until a qualifying transaction is matched.
How do card-linked offers work, step by step?
The mechanic is a match, not a redemption. Nothing is scanned or keyed at payment: the offer is reconciled afterwards against card-linked transaction data supplied by the issuer or the network.
- The brand or merchant publishes an offer into an issuer programme, a scheme programme or a card-linked API.
- The shopper activates the offer in their banking app or publisher app, enrolling a specific card.
- The shopper pays with that card at the participating merchant, with no extra step at payment.
- The transaction is matched to the offer after authorisation or at settlement, using merchant identifiers, amount and timing.
- The reward is credited to the shopper as cashback, statement credit or points, typically days later.
The limitation is in step four. Matching runs on merchant and amount. Most programmes have no sight of the products in the basket, so the offer qualifies on where the shopper spent and how much, not on what they bought.
Where card-linked offers work well and where they fall short for FMCG brands
Card-linked offers are strong when the objective is store-level spend across a wide shopper base. They weaken when the objective is shifting a specific product off a specific shelf.
The strengths are genuine. Issuer distribution puts offers in front of a large base of enrolled cards without a brand building any audience of its own. Attribution closes against a real card transaction rather than a modelled impression, which is more defensible than most media measurement. And the commercial model is pay on performance, so unredeemed offers cost nothing.
The limits matter more to FMCG. There is an activation step, and every activation step loses shoppers who never open the app. The reward arrives after the visit, so it cannot influence the decision made in the aisle. Most programmes cannot see the SKU, which means a brand funding an offer at a grocer is paying against total store spend rather than against its own product. And the offer is invisible at payment, the one moment when every shopper is attentive, holding a card, and standing in the store.
How can a brand-funded offer reach shoppers on card machines?
Software running on Android card machines supplied by partner payment providers can recognise a returning card and display a brand-funded offer or message on screen while the shopper pays. There is no app download, no sign-up and no extra tap from the shopper.
Recognition relies on the card's payment token rather than a name, email address or phone number. Using card tokens as a join key lets a returning shopper be recognised without the shopper sharing personal details at payment.
Distribution runs through acquirers, PSPs and ISOs, so reach follows their merchant estates rather than issuer enrolment. A brand buys presence in the stores those providers serve.
Targeting progresses in stages:
- An untargeted image or message shown on card tap, useful for awareness across a defined estate.
- Card BIN targeting at chosen merchants and merchant categories, narrowing to card types and store sets.
- SKU-level targeting where an EPOS integration supplies basket data, so an offer qualifies on the product bought.
Illustrative example. A soft-drink brand funds a stamp-style reward at independent convenience stores. The shopper taps, the returning card is recognised, the screen shows progress towards the reward, and the brand pays only on qualifying activity. No results are claimed here; the example describes the mechanic only.
Card-linked offers and offers on card machines compared
The fair comparison is about timing and granularity, not about which channel is better. One reaches shoppers before and after the visit; the other reaches them during payment.
| Criterion | Card-linked offers | Offers on card machines |
|---|---|---|
| Where the shopper sees the offer | Banking app or publisher app, before or after the visit | Screens on card machines, during payment in store |
| Activation needed | Yes, the shopper enrols a card | No, the returning card is recognised by its payment token |
| When the reward lands | After matching, usually days later | At payment or on the next qualifying visit |
| Match granularity | Merchant and amount | Merchant, card BIN, and SKU where an EPOS integration supplies basket data |
| Who distributes | Issuers, card schemes, publishers and card-linked APIs | Acquirers, PSPs and ISOs across their estates of card machines |
| Data the brand receives | Matched transaction events and redemption reporting | Visit frequency, recognised returning cards, and campaign reporting by store |
| Best suited to | Driving store-level spend across a wide enrolled base | Influencing the purchase decision in store and building repeat visits |
What should a brand ask before funding offers in either channel?
The questions are the same in both channels. The answers differ, and that difference is where the budget decision sits.
- What reach does this give me in the specific stores, retailers and regions I actually sell through?
- How are redemptions matched, and what evidence sits behind a reported redemption?
- Is attribution at merchant level or product level, and what would it take to get to product level?
- What is the consent model and the lawful basis for processing, measured against UK GDPR guidance from the ICO?
- How is card data handled, and does the provider meet PCI DSS requirements?
- How is the offer funded and settled, and who carries the liability if a redemption is disputed?
- Who supports the merchant when something goes wrong on the card machines or in reporting?
Two of these decide most campaigns. If the channel cannot tell you whether your product was in the basket, you are buying store spend. If the merchant has no support route, the campaign stops the first time a screen behaves unexpectedly.
What acquirers and PSPs gain from brand-funded offers
Brand-funded campaigns create a revenue line that is not tied to processing margin. The payment provider shares in campaign spend from brands, using card machines already deployed.
The retention argument is as strong as the revenue one. Funded offers, returning-customer recognition and reporting give merchants a reason to stay with a provider that goes beyond price. Value-added services turn an estate from a processing footprint into a distribution channel.
For product leads evaluating this, the deployment model matters: the services run through the existing TMS, per TID, and the merchant relationship stays where it is. Our guide to card-linked loyalty for payment providers sets out how that works across an estate.

What I have learned building brand-funded loyalty on card machines
Zeal does not sell card machines. Our software reaches merchants through acquirers, PSPs and ISOs, so in my experience every conversation about brand-funded offers starts with a payment provider's estate rather than a merchant's shopping list. In the UK, Zeal is live with Adyen, DNA Payments, Elavon, Lloyds Cardnet, NMI, Viva Wallet and Worldpay.
More than 30,000 merchants have been activated across payment providers, and partners have signed an activation pipeline covering 4 million payment terminals. In my experience, that reach only exists because the distribution runs through the people who already own the relationship with merchants' card machines.
The view I keep coming back to is simple: card machines are the last unbought screens in retail. Every shopper looks at them, and they sit in the exact second a purchase is confirmed.
Frequently asked questions
Are card-linked offers the same as cashback?
Cashback is one way a card-linked offer pays out, but the two are not identical. A card-linked offer is the mechanic that ties a reward to a card and matches it to a transaction; the payout can be cashback, statement credit or loyalty points.
Do shoppers need an app for card-linked offers?
Usually yes. Activation normally happens inside a banking app or a publisher app, which is where the shopper enrols the card. Offers on card machines work differently: the returning card is recognised at payment, so no app download is required.
Can card-linked offers see which products were bought?
Generally not. Matching runs on merchant identifiers and transaction amount, so the programme knows where and how much, not what. SKU-level visibility requires EPOS integration or receipt data.
What are the alternatives to a card-linked offers API such as Fidel API?
There are three practical routes. Issuer and scheme offer programmes give breadth through banking apps. Receipt-scanning apps give product-level detail but ask more of the shopper. Offers on card machines give presence during payment through acquirer and PSP estates. For a direct breakdown, see how card-linked APIs and loyalty on card machines compare.
Can brand-funded offers appear on all card machines?
No. Offers appear only on supported card machines supplied by partner payment providers. Merchants on other providers can register interest, and coverage expands as more providers enable the service across their estates.
