Credit cards often offer more fraud prevention and protection than debit cards. If you use a debit card and purchases are made without your permission, the money is withdrawn directly from your account. Debit cards should be treated like cash. On the other hand, if you use a credit card, you have more time to dispute fraudulent charges and the bank can withhold payment while they investigate the incident.
Aside from checking your bank statements, it is a good practice to review the transaction history of your credit card and bank accounts regularly to check for any unusual activity, such as unauthorised payments. If you spot anything out of the ordinary, alert your bank immediately.
