A debit card is a plastic card enabling the cardholder to purchase goods or services, or withdraw cash, the cost of which is immediately charged to his or her bank account. Debit cards are used to activate POS terminals in supermarkets, gas stations and stores. Together with credit cards, they are commonly referred to simply as bank cards. Debit cards are widely used to pay for goods and services. They are used in conjunction with a current bank account. The amount of the purchase is immediately debited from the account and no credit is involved, hence its name. A smart card is a secure, portable, tamper-resistant data-storage device. It is the exact size of a credit card and contains a computer with as much power as the original minicomputer.
