If you are a student, the Discover it® for Students credit card is good start. The card has no annual and no activation fee. There are no hidden fees at all, but you should read the terms and conditions to be aware of penalty fees. The annual percentage rate (APR) is the interest rate that will be applied to your balance if you don’t pay it off in full each month. Your APR will be determined by the credit issuer and will depend on your creditworthiness. The card also has a rewards program, which allows you to earn 1% cash back on all your purchases, and an additional 5% cash back on rotating categories every quarter.
