What is the difference between a Debit Mastercard and a credit card?

This new Debit Mastercard is an ATM card, i.e. a debit card and not a credit card, even if you can use it to make payments to all Mastercard merchants. Whenever you pay using this card, the amount will be immediately debited from the account. When using a credit card, your payments are added together and the total amount is debited from the account once a month.
