How do prepaid mastercards work?

Prepaid Mastercards are loaded with a specific amount of money that can be spent until the balance is depleted. Users can use them for purchases anywhere that accepts MasterCard, both online and in-store. Unlike credit cards, they do not allow for borrowing beyond the loaded amount, making them a budgeting tool. To use a prepaid Mastercard, you simply swipe or enter the card information, and the transaction amount is deducted from the available balance.
