Safari on iOS 7 has a new feature that lets you auto-fill credit card data on websites. Just like passwords, credit card data can also be stored to be used on websites that require credit card information.
Of course, this comes with the ample security measures that prevent other people from misusing the credit card autofill feature on your iPhone/iPad.
Here’s more on setting up the credit card autofill feature securely and making sure it remains safe:
How to Add Credit Card Autofill in Safari iOS 7 on iPhone, iPad & iPod
Step #1. Open the Settings app.
Step #2. Tap on Safari.
Step #3. Now tap on Passwords & AutoFill.
Step #4. If you don’t have passcode lock setup already, you will be prompted with a dialog. You can either set up a passcode lock which will be used every time you authorize a credit-card autofill or continue without setting up a passcode. It is highly recommended that you set up a passcode.
Step #5. Now, credit card autofill is ON, but you have to save credit cards that will be used. To do this, tap on Saved Credit Cards.
Step #6. Tap on Add Credit Card.
Step #7. Fill up the details. You can use the Description field to identify the card type (comes in handy when you are on a page that requires credit card info.
Protecting Your Information
The only line of defense to protect this information is your passcode lock. When you have a passcode enabled and use it to authorize credit card autofill, the iPhone/iPad will prompt you for a passcode entry whenever the credit card info is being used.
Also, whenever you are on a page that requires credit card information, make sure the page URL starts with https:// (the ‘s’ stands for secure). A secure connectivity which is authenticated by valid certificates makes sure your credit card data cannot be “lifted.”
When you store your credit card info on your iPhone/iPad, it’s best not to let others access these areas of your iPhone/iPad.
