# unsupportedPrimaryAccountIdentifiers

An array of Apple Pay cards to exclude from payment.

```
var unsupportedPrimaryAccountIdentifiers: [String] { get set }
```

## Discussion

Use this property to exclude Apple Pay cards you’ve issued from being used as a payment option by adding the [`primaryAccountIdentifier`](/documentation/PassKit/PKSecureElementPass/primaryAccountIdentifier) of the cards you want disallowed. For example, if a person is topping up a stored value card, you can exclude the Apple Pay card being topped up from the payment options.
