How to add a credit or debit card to Apple Pay

Apple Pay lets you make in-store purchases with your iPhone, and online purchases with your iPhone or iPad, with just a touch of the Home button or the tapping out of a passcode. It makes it easy to start ditching your wallet for your device. All you have to do is add your credit or debit cards.

Bank authorization

Different banks have different procedures when it comes to authorizing cards for Apple Pay. Capital One, for example, automatically adds and activates your card for Apple Pay after you accept your terms and conditions. Citibank, however, requires an activation code; to get it, the bank will robo-call or text the number you have on file.

Troubleshooting Apple Pay

If you're having trouble getting Apple Pay to accept your card, the simplest solution is to just try entering in your information again; I had no luck activating my cards on Monday evening, but entering in the same information on Tuesday morning worked like a charm.

Worst-case, you may just need to call your card issuer. For example, the last card I tried to set up never sent the verification code to my phone number on file, so I had to manually retrieve it through the phone system. That call was pretty painless, however; I had Apple Pay fully up and running on that card within ten minutes.
