What "debit card" means in finance

A debit card is a payment card that allows the cardholder to make purchases or withdraw cash from an ATM using funds from their linked bank account. When a purchase is made, the funds are immediately transferred from the cardholder's account to the merchant's account. A debit card may also be used for online transactions, bill payments, and other types of transactions. Unlike a credit card, a debit card does not involve borrowing money, and the cardholder can only spend the funds that are available in their account.
