MasterCard Card

This one is pretty simple: it's any credit card in the MasterCard network. Pull out that stack of cards you have in your wallet. The ones with the little MasterCard logo in the corner are the MasterCard cards.

The rest of them are probably Visa cards. There are a handful of credit card networks in the U.S., but MasterCard and Visa represent the big two in the industry.

No matter who the issuer is (or whether the card is affiliated with some other brand as well...Amazon, Disney, various sports teams or charities, etc.), your MasterCard will be accepted by any merchant that belongs to the company's network.
