It’s very easy to put your credit card information on your phone to Apple Pay, Google Pay, or any other mobile wallet. But how do these apps work?

How do mobile wallets work?

If you’re one of the 85% of Americans who own a smartphone, chances are it has a mobile wallet app built into it. These are fairly easy to set up – you’ll be asked to enter your card numbers, expiration dates, CVV numbers, and information. You may have to verify card information via two-factor authentication. This is for your protection and to ensure that the person who stole your credit card information can’t just add it to their mobile wallet without some additional actions (like accessing your email or mobile phone number).
