Apple pay with multiple cards and in app purchase

[john991]

When buying something thru an app using apple pay, which credit card does the app use?

Is it the default card or can you select which one? i.e. groupon, apple store, starbucks, uber, etc.

As I didn't see anything on the web about this.

Thanks

Default or you can change it
