When it comes to choosing a student cash-back credit card, there are a few things you'll want to compare. First, look at the percentage of cash back each card offers. This will give you an idea of how much money you can earn back on your purchases. Next, check whether there's an annual fee. Some cards charge an annual fee, which can eat into your cash-back earnings. Finally, take a look at the APR you'll pay on purchases. If you plan to travel outside the U.S., make sure to check for foreign transaction fees. The Discover it Student Cash Back Credit Card is a great option because it has no annual fee and offers a low intro APR.
