Question

Mobile development

It is supposed to be an application that stores bank card data and can work with NFC.
Is it possible to refuse the publication of such an application in the markets and for what reasons?

Answer 1

depending on how you store them. It is forbidden to store card data on the phone. You can store the card id, the last 4 digits of the card number and the owner's name. even when working with a card, you do not use this data, but generate a special token by which the bank understands what kind of card, etc. To clarify the information, you need to look at the documentation of the bank with which you are going to make a payment.
