what do debit cards provide
If you use a debit card at a retail store, you or the cashier can run your card through a scanner that enables your financial institution to verify electronically that the funds are available and approve the transaction. Most debit cards also can be used to withdraw cash at ATMs (automated teller machines). Why do people use debit cards? For many people, it is more convenient to carry a small, plastic card instead of a bulky checkbook or a large amount of cash. Using a debit card is also easier and faster than writing a check.
The credit companies offer the rewards as an incentive for you to use the credit card and would not do so if they lost money on the transactions. 1  Consider using credit cards for hotel reservations and car rentals. 2  For daily purchases, your debit card can help you stick to your budget.
