With iOS 7, Apple added a new feature in iBooks, iTunes and the App Store that allowed users to scan iTunes gift cards with the device’s camera rather than manually entering the string of characters on the back of the card. Now in iOS 8, you can use the device’s camera to scan and enter credit card information.
To add your credit card for purchases open up Settings and tap on Safari.
Then tap on Passwords & AutoFill. Here you will notice that by default that Names and Passwords, and Credit Cards is turned on by default. To add a credit card, press Saved Credit Cards. When you press on Saved Credit Cards, it requires you to enter your devices’s password to continue.
Once you enter in your device’s password you will be able to add a credit card by pressing on Add Credit Card. If you happen to see credit cards already listed here and are not sure why they are there, that indicates you were using iCloud Keychain which stores any credit card information you have entered in and syncs across your iOS devices and your Mac. Then you are able to scan the credit card by pressing on the words Use Camera up at the top in blue.
When doing this on the device, a white box appears with Position Card in this Frame.
When doing this on the iPhone, the phone vibrates when it detects the card numbers. Sometimes it will also pick up the expiration date, but most of the time I had to enter it in manually along with my name on the card. For security purposes it will not store the CVC number. Testing this with vertical credit cards, it was not able to detect the credit card numbers.
Now when you go shopping online using Safari, you are able to have your credit card information be filled out very quickly for you. When you tap in the box that says Name on card or Card Number, you get options to either enter in the credit card information or AutoFill Credit Card.
Tapping on AutoFill Credit Card shows you the credit cards you have stored locally on the device or in iCloud Keychain, or it allows you to scan in a new credit card right then.
Then when you go shopping online it will fill in your name, credit card number and expiration date. You do have to manually enter in the security code on the back of the credit card.
