CardJar currently publishes recognition data for 508 loyalty schemes across 12 countries. The largest listed catalogues are the United States with 86 schemes and the United Kingdom with 84.

Recognition is not the same as compatibility

A recognized scheme arrives with the expected retailer name, color and membership-number label. CardJar can therefore turn a scan into an organized card with less manual setup.

An unrecognized retailer is not rejected. The user can type a name, choose a color and keep the card beside the recognized entries. CardJar treats recognition as convenience rather than permission.

The actual technical boundary is the code. A stable supported barcode or QR code can be stored. A retailer that generates a fresh code for each visit may still require its official app.

Why the catalogue is bundled locally

A wallet could fetch each retailer’s logo or metadata when a card is added. That request would reveal that the device asked for a specific shop.

CardJar takes a different route. All 12 country lists, their retailer identities and visual information are compiled into the application. The complete published catalogue is only a little over one hundred kilobytes, according to CardJar.

This design produces three concrete outcomes:

Recognition works offline. A basement car park, flight or poor-signal supermarket does not block the match.
No catalogue lookup exposes the retailer. Opening or adding a recognized card does not require a logo request.
Updates arrive with app releases. A new catalogue version is distributed as part of the application rather than assembled from live queries.

That architecture supports CardJar’s larger privacy model: cards, retailer data and barcode drawing remain local.

What happens during a scan

CardJar reads the barcode and the nearby words printed on the physical card or screenshot. The surrounding text helps distinguish schemes whose membership numbers alone are not unique enough to identify a retailer.

The recognition models are included in the app. CardJar states that the image, extracted words, result and fact of the scan do not leave the phone.

Former Stocard users can apply the same process to an album. The CardJar screenshot migration flow reads multiple saved images, identifies supported schemes and lets the user review the resulting cards before saving.

Coverage on phone and watch

The full jar remains on the phone. Users can mark frequently used cards as favorites, and those selected entries can travel to the CardJar Wear OS app. The watch stores its own copy rather than requesting the card from a CardJar server at checkout.

CardJar’s iPhone and iPad apps use the same account-free collection model. There is currently no Apple Watch app.

What this public proof establishes

The coverage page is inspectable evidence of three product facts:

the exact published scheme count;
the exact country distribution;
the local catalogue design behind recognition.

It does not claim every loyalty program in those countries is preconfigured. CardJar’s stronger point is that a missing catalogue entry does not prevent a stable card from being stored manually.
