How to show a loyalty card barcode on Apple Watch

Why show loyalty cards on your wrist?

Your hands are full with a basket or a coffee, and the phone is at the bottom of a bag. The Watch app solves exactly that: raise your wrist, the door scanner reads it, nothing to dig out. It works just as well for a club membership card.

How do I get a barcode on my Apple Watch?

  1. On the iPhone, add your cards in StoreCard as usual.
  2. Make sure the StoreCard Watch app is installed on your Apple Watch. If it is not, install it from the App Store on the Watch or from the Watch app on the iPhone.
  3. Open StoreCard on the Watch. Your cards appear in a list with their names and companies.
  4. Tap a card to show its barcode, and hold the Watch face flat towards the scanner.

There is nothing to set up on the Watch. Adding cards happens on the iPhone; the Watch has no scanner or form of its own, and with no cards it tells you "Add cards on your iPhone".

How do cards get to the Watch?

Whenever you add, edit or delete a card, the iPhone sends the updated list to the Watch in the background. The Watch keeps its own copy of the cards, so the list is there when you open the app. The Watch settings screen shows Last Sync, the time of the most recent update.

If a new card has not arrived, open StoreCard on the iPhone with the Watch nearby and connected, then open the Watch app again.

Can I show only my favourite cards on the Watch?

Yes. In the StoreCard Watch app settings, switch on Show Favorites Only. The list then shows just the cards you marked as Favorite on the iPhone, which keeps a long list short on a small screen. If no card is a favourite, the Watch says No favorite cards.

Common problems

  • No cards on the Watch at all: add at least one on the iPhone and keep both devices connected for a moment so the first sync can happen.
  • A card shows but not its code: the number may not fit the chosen format. Fix it on the iPhone with Edit and Change Format.
  • Some older laser scanners simply will not read any watch screen, flat and square or not. Keep the iPhone as a backup for those tills.

The Watch app is free, and so are all its features.

Questions and answers

Do I need Pro to use the Apple Watch app?
No. The Watch app, the card list and the barcode are free.
Can I add a loyalty card directly on the Apple Watch?
No. You add cards on the iPhone and they are copied to the Watch automatically.
Does it work if my iPhone is not nearby?
The Watch keeps a copy of your cards, so the list is available once it has synced. New or edited cards only arrive when the Watch and iPhone can talk to each other.
Why won't the scanner read my Watch?
Long barcodes are drawn small on a Watch screen, and some scanners struggle with it. Hold the Watch still and closer, or show the card on the iPhone instead.
