QUICK ANSWER
A debit card spends money already in your account; a credit card borrows money you repay later. Used carefully, paying the full balance every month, a credit card often gives better fraud protection and rewards. If you might carry a balance, a debit card avoids interest and keeps spending in check.
How each card works
With a debit card, money leaves your bank account immediately or within a day. With a credit card, the bank pays the shop and you repay the bank later. Pay the full statement balance by the due date and you usually pay no interest; pay less and interest is charged on what remains.

| Debit card | Credit card | |
|---|---|---|
| Whose money | Yours | The bank’s, until you repay |
| Interest | None | Charged if you don’t pay in full |
| Fraud protection | Money is gone until the bank investigates | Disputed charges usually don’t affect your own cash |
| Rewards | Few or none | Often cashback, points or air miles |
| Effect on credit history | Usually none | Builds history if paid on time |
| Risk of debt | Low | Higher if you overspend |

Frequently asked questions
Does using a credit card hurt my credit score?
Not if you pay on time. Late payments and using a very high share of your limit can lower it.
Is it safe to use a debit card online?
Generally yes on trusted sites, but if fraud happens your own money is tied up while the bank investigates. Many people prefer credit cards online for that reason.
Are rewards worth an annual fee?
Only if the rewards you actually earn are worth more than the fee. Compare based on your real spending.
