A debit card is an electronic payment card that deducts money directly from a customer’s current account as they transact. A debit card purchase is usually made with or without a personal identification number (PIN). A debit card also allows the user to withdraw money from his or her current account through an ATM. Unlike a credit card, no interest is charged on purchases made with a debit card, and the customer’s credit history will not be affected by his or her debit card purchases.
