What is the difference between credit cards and debit cards?
When you are making purchase with your credit card, your card issuer is loaning you the amount of purchase upto your credit limit. Naturally you are expected to pay an interest on the amount you owe. But debit cards are linked to your savings and/or checking account. When you are making a transaction with your debit you are actually taking the money from your own account. So debit cards are electronic form of checks. They are issued by banks where you have checking/savings account.
