A common phone call that new credit cardholders get from their bank is an offer for credit card add-on products, such as protection against fraud and identity theft. Payment protection is another service offered regularly, providing a monthly payment to the cardholder’s account if they lose their job or are sick in the hospital.

Credit monitoring and debt-cancellation products are optional and are paid for through a monthly or annual fee.

A credit card’s mobile app can give you immediate access to your account, making it easier to track purchases, make payments, review monthly statements, report a lost card and view rewards, among other things.

But not all mobile apps are the same, and knowing what’s available can make it easier to choose a credit card and find the features you want in an app. Of course, that’s after you’ve found the card with the best interest rate and rewards you want.
