With Apple Pay you can add your Visa, Master Card, American Express, Discover,
and Debit cards to Wallet on your iPhone and iPad!
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 and a scan of your fingerprint. It makes credit and debit card purchases easier and more secure. All you have to do is set it up and start using it!
If you ever want to add more credit or debit cards you can just repeat these steps.
Note: Apple Pay's photo-detection only works on with embossed numbers; if you have a credit or debit card with flat numbers, you'll have to enter it manually.
