# vasMerchants

A global list of merchants to use when reading loyalty cards.

```
var vasMerchants: [VASRequest.Merchant]
```

## Discussion

When you try to read a loyalty card from your [`PaymentCardReaderSession`](/documentation/ProximityReader/PaymentCardReaderSession)
object, specify a custom [`VASRequest`](/documentation/ProximityReader/VASRequest) object to override this list.
