You can also apply for a credit card to go with your account. To do so, you need to be at least 18 and have a regular income. Credit cards can be used to pay for goods and services too. Unlike when using a bank card, the amount is not debited from your account immediately. Instead, the credit card company collects the amounts and sends you a bill once a month for all the payments you have made using the card. Your account will be debited a few days later.
