Apple released their latest update to the iPhone 6, 6 Plus, iPad Air 2, and iPad mini 3 and eventually the Apple Watch to allow for Apple Pay, as shown in their iPhone release, to start working today.
Apple Pay allows for a one-touch payment using credit or debit cards that have been stored through a Touch ID authentication process. In comparison to existing products, Google Wallet, for example, authenticates with a PIN number such as a debit card does when swiping it at the store.
The Passbook application, which is already used to store tickets, coupons, etc. will now be able to save credit and debit cards.
Adding the card information is as comfortable as either using the iSight camera to enter in the card information or the information can be manually typed in. When adding cards, the first card added becomes the default payment card, although this can be changed at any time by going to Passbook and changing the defaults from there.
At this time there is a list of participating banks such as Bank of America, Chase, Wells Fargo, Capital One, Citi, and American Express with many more on the way. We can be sure that the list will grow as more users adapt to the Apple Pay technology.
To get this update now, provided you have an eligible device, go to Settings and get the latest System Update.
