Mastercard's slogan is Priceless: There are some things money can't buy, but for everything else, there's Mastercard. One of the things that money cannot buy is a new gender. No matter the number of surgeries, the extent of cross-dressing, or the name-changes, a man cannot become a woman and a woman cannot become a man. However, Mastercard is willing to play pretend with those who want to act like someone they are not.
