Finding the right credit card will take some research. You'll need to bear the following in mind.

The attraction in getting a student credit card lies in the terms and conditions of the cards: student credit card providers will allow you to borrow without having any regular income at all.

Shop around to find the cheapest credit card and don't restrict yourself to student credit cards. There are some really low interest cards around that don't have a minimum income requirement.

Some student credit cards offer money off in certain shops, but these are sometimes the same shops in which you'll get discounts with your NUS card. If this isn't the case and the discounts on offer are ones you'll take advantage of, a student credit card could still be a good deal for you.
