Where Safari stores your credit cards
When you pay for anything on the Internet may not note as Safari will take and will allow you to save a credit card number. Many tend to blindly click “Yes”, not knowing that the data is stored on the iPhone.
To access your saved credit and debit cards, you need to open Settings — Safari — AutoFill. Here at the very bottom there is a section of “Saved credit cards”. The section contains all the information on the cards except for the verification code CVV. Other data like the full number and expiration date available.
Of course, just to go to this menu impossible. Before entering you will be asked to make a fingerprint or enter a password. Although data is securely protected, it is another reason not to give your password to anybody.
