CardJar

Coverage · Ireland

30 Irish loyalty cards, recognised on sight.

Scan any of these and CardJar knows what it is: the scheme's name, its colour, and what the number on the back is called. The list is compiled into the app, so nothing is fetched and nothing is logged.

Every Irish scheme in the catalogue

Colours come from each retailer's own published brand guidance, and every one is checked to keep text readable against it. Names and colours are used to identify a card you already hold; CardJar has no relationship with any of these retailers.

Other countries CardJar covers

CardJar also recognises the schemes people carry in Germany, Poland, France and Spain.

Carrying a card that is not on this list?

Add it anyway. Type a name, pick a colour, scan the barcode, and it behaves exactly like the ones CardJar recognises. The catalogue saves you thirty seconds; it never decides what you are allowed to keep.

Tell us what is missing and it can ship in the next release.

Ready before the person in front of you has packed

Open, tap, hold it out. The till screen turns the brightness up on its own, draws the barcode at whole pixels so a laser has a clean edge to find, and stays white in dark mode because a tinted barcode is a barcode that does not scan.
