Can I store credit card information in Preference?

Question

Android

I want to make life easier for the user so that he does not enter data every time he wants to make a payment. Is it safe to store them in Preference (card number, expiration date, cvv)?

Answer 1

You have already been given a link to the card data storage standard. Anything that doesn't meet the standard is "no".

Answer 2

To begin with, the user must be given a choice: to store or not. And then choose where to store. In any case, it is better not to store in the open.
