Can you explain the difference between a debit card and a credit card?
assistant
A debit card is linked directly to your bank account, so when you use it, money is taken directly from that account. A credit card, on the other hand, is not linked to an existing bank account; instead, it allows you to borrow money from the lender in order to make purchases. When you make a purchase with a credit card, the amount of money you owe increases by the amount of the purchase, but you can pay off the balance at any time without incurring additional interest.
