How this guide was prepared. Last updated October 2026. It draws on Brandmovers' experience designing loyalty programs that capture purchases across digital and physical channels, including the program example cited below. It also draws on California privacy regulations, checked at their source. |
A contactless loyalty program lets members join, earn and redeem without presenting a physical loyalty card, using NFC taps, digital wallet passes, QR codes or receipt and ticket submission. The convenience is real, but the bigger change is in the data: each mechanic decides which purchases the program can see and connect to a member.
This guide covers what each mechanic does well and where it falls short, how to choose and combine them, what Metrolink's transit program shows about connecting physical purchases to digital accounts, what the platform behind them needs, and the privacy and measurement questions to settle before launch. Wallet passes are covered in depth in the mobile wallet loyalty guide, and receipts in the guide to receipt validation benefits.

Because it closes gaps: purchases made without a card, in another channel or through a retailer can become visible and attributable to a member.
A card-based program sees an in-store purchase only when the member presents the card or is otherwise identified at checkout. Every purchase made without it, because the member forgot it, paid another way or bought through a channel where the card does not work, is invisible. Contactless mechanics reduce those gaps in different ways: by linking earning to how the member pays, by keeping a pass on the phone, or by letting the member submit proof of a purchase the program could not see. More complete purchase records support better segmentation, personalization and measurement. The gaps that remain depend on which mechanics a program uses.
A phone tapped on a compatible reader can present a member's loyalty pass at checkout; linked payment cards are a related, processor-based approach.
NFC (near field communication) lets a phone or card exchange data with a reader held a few centimeters away. In loyalty programs it is used to present a loyalty pass from a digital wallet at the same tap as payment. A related approach links a member's payment card to their account so qualifying payments with that card earn points, whether tapped, inserted or keyed online; it works through the payment processor rather than the tap itself, and the member links the card once. Either way, the member then does nothing beyond paying, which closes the "forgot my card" gap.
The limits are infrastructure and integration. Wallet-pass NFC needs certified terminals and point-of-sale software that supports the wallet providers' protocols; the mobile wallet loyalty guide covers Apple's and Google's requirements. Payment-linked earning needs integration between the payment processor and the loyalty platform. Programs without that setup can start with barcodes or QR codes on the same pass.
A wallet pass keeps the program on the member's phone between purchases, showing balance and status and allowing updates without an app.
A loyalty pass stored in Apple Wallet or Google Wallet can show the member's current balance, tier and offers, and can update when the program's data changes. Both platforms can surface a pass at relevant moments, within limits each sets (the mobile wallet loyalty guide covers those limits), so the program is visible between purchases without asking the member to open an app or an email. Whether that visibility raises redemption or visit frequency is worth testing in your own program against members without a pass. The wallet guide covers pass updates, notifications and enrollment flows in detail.
When purchases happen where the program has no checkout connection: through retailers, offline or in channels the brand does not control.
A unique QR code on packaging or a receipt gives the member a way to earn for a purchase the program cannot see directly; a code on signage can lead to enrollment or a submission page but does not prove a purchase on its own. Submitting a receipt goes further: depending on what the program captures, it can show the retailer, date, total and other items on the receipt, not only the qualifying product. These mechanics ask more of the member, a scan or a photo for each purchase, so they work best when the reward is worth the effort and the confirmation comes quickly. People who submit are self-selected, so the data describes engaged buyers rather than all buyers.
Match each mechanic to where members buy and what data you need, then add mechanics where an uncovered channel is large enough to justify the cost.

For a program moving off physical cards, a wallet pass is often the easiest first step because adding it needs no checkout changes, though it records purchases only where checkout staff or scanners read its barcode or QR code. Receipt or QR submission then extends coverage to channels the program cannot see, and NFC follows where checkout systems allow it. The right order depends on where your members buy. Keep a fallback, such as a printed card or a lookup at checkout, for members without a smartphone or who prefer not to add a pass, so moving to contactless does not shut them out.
That a program can connect non-digital purchases to member accounts by giving members several ways to submit them.
Metrolink, Southern California's commuter rail operator, launched SoCal Explorer on BLOYL™, Brandmovers' enterprise loyalty platform, to reconnect with riders after ridership fell during the pandemic. Its challenge was "Heavy reliance on physical tickets (50%+ of transactions) with no way to track customer behavior." Riders earn points for every mile traveled, "whether through digital tickets or by submitting physical tickets via photo, barcode scan, or code entry", and Brandmovers' ValidSpend™ validates the physical tickets and associates the purchases with riders. The case reports a 15% increase in average monthly transactions among members and a 60% active engagement rate among enrolled riders (disclosed by Brandmovers; Metrolink case study). It reports no comparison group and does not say whether submitted physical tickets count toward transactions, so the figures show the program in use rather than a measured lift.
The lesson for other programs: contactless loyalty is not only for retailers with tap-enabled checkouts. Programs whose members buy in several ways need a route for each, including the least digital one. Metrolink gave riders three ways to submit a physical ticket (photo, barcode scan or code entry), which matters for a mechanic that asks for effort on every purchase.
Real-time posting, one member profile across channels, updates to wallet passes, and validation for any submitted receipts or tickets.
BLOYL includes OCR receipt validation with built-in fraud protection, real-time dashboards, A/B testing against a control group and bidirectional CRM and customer data platform flows, so contactless purchase data can feed member records and analytics. Wallet pass delivery and NFC acceptance also depend on the pass provider and point-of-sale setup in each program.
Location-based alerts, linked payment cards and receipt contents all involve personal data, so decide what you collect and tell members before they opt in.
Location features should rely on the wallet platforms' own relevance settings or on members' explicit permission, and should not be used for anything members were not told about. Linking a payment card to a loyalty account means handling payment-related data, so use the processor's tokenized identifiers rather than storing card numbers, and say how linked transactions are used. Receipts and tickets can show other purchases, places and times; keep only the fields the program needs.
Where members are rewarded for providing personal information, California's CCPA regulations require businesses covered by the law to give a Notice of Financial Incentive that explains "the material terms" so "the consumer may make an informed decision about whether to participate", available "before opting-in" (Cal. Code Regs. tit. 11, section 7016). Other states have their own privacy laws. This is general information, not legal advice.
Separate better counting from real behavior change: more captured purchases is not the same as more purchases by members.
When a program adds a contactless mechanic, recorded purchases per member usually rise partly because purchases that already happened are now counted. To see whether behavior changed, compare members who adopted a mechanic with similar members who did not, before and after, or roll the mechanic out to some locations or segments first. Adopters tend to be more engaged to begin with, so a staggered rollout gives the cleaner comparison. Track adoption rates, the share of purchases attributed to members, and repeat purchase and redemption among adopters. Weigh the results against costs: terminal certification, integration, pass management, validation, support and the added points liability from rewarding purchases that were already happening. The guide to loyalty program analytics covers comparison methods.
Contactless loyalty is mainly about seeing more of what members buy and connecting it to them. Use NFC where checkout systems allow it, wallet passes to keep the program present between purchases, and QR codes and receipt or ticket submission for purchases the program cannot see at checkout, as Metrolink did for physical tickets. Settle privacy and consent before launch, and measure behavior change rather than counting gains.
