What is a Credit Card & How Do They work?

A simple guide to help you understand credit

Credit cards explained

A credit card could be a convenient and flexible way of borrowing money. Credit cards allow you to spread the cost of your purchases over time.

Before you apply for a credit card, it's important that you know about what it could cost you to use it, and that you only borrow what you can afford to pay back. To get the most out of your credit card, it's crucial that you're able to meet your payment dates – and pay what you owe in full every month.

Whether you’re used to credit cards or it’s all new to you, it’s always a good idea to think about how you manage your account. These short videos can help.
