Apple Pay lets you use multiple credit and debit cards, so you can easily switch between them when you want to make a transaction. The default credit or debit card, however, is always the fastest and easiest to use. So, you'll want to make that card the default. Luckily, Apple Pay makes that fast and easy to do as well.
How to choose a default credit card for use with Apple Pay
- Launch the Settings app on your iPhone or iPad that's compatible with Apple Pay.
- Tap on Passbook & Apple Pay.
- Tap on Default Card.
- Tap on the card you want to use as your default.
That's it! Unless you manually change the card you're using when making a purchase, the selected card will always be used.
