Debit card
Used with the convenience of other types of purchase cards (credit cards, charge cards, gift cards, etc.) a debit card allows a consumer to make purchases by deducting funds directly from a personal checking account.

A debit card (also known as a bank card or check card) is a plastic card which provides an alternative payment method to cash when making purchases. Functionally, it can be called an electronic check, as the funds are withdrawn directly from either the bank account (often referred to as a check card), or from the remaining balance on the card. In some cases, the cards are designed exclusively for use on the Internet, and so there is no physical card.[1][2]
The use of debit cards has become widespread in many countries and has overtaken the cheque, and in some instances cash transactions by volume. Like credit cards, debit cards are used widely for telephone and Internet purchases.
Debit cards can also allow for instant withdrawal of cash, acting as the ATM card for withdrawing cash and as a cheque guarantee card. Merchants can also offer "cashback"/"cashout" facilities to customers, where a customer can withdraw cash along with their purchase.
