One of the biggest mistakes college students make has something to do with money, especially with credit cards. However, you can make credit card work for you more than just a tool for online shopping. You can use it to build your credit, especially when buying an apartment or applying for a mortgage in the future.

If you don't have any student loans and you're 21, you can start looking into different credit cards to build your credit score. Here are 5 best starter credit cards for students which have the lowest interest rate or annual percentage rate.

Capital One Secured MasterCard

This is for the total beginner because it allows you to build a credit without getting into debt. The secured card lets you deposit $49 - $200 as a collateral and gives you a $200 credit line. This might not sound much but after using it and paying on time for five consecutive times, you can apply for a higher credit line which can be up to $3,000.

Discover

This starter credit card is for those who want to earn more through their grades. Discover gives 5 percent cash back on purchases. It also awards students $20 for every school year their GPA is above 3.0. Furthermore, it doubles your cash back for the first year of your use. So if your cash back is $50, Discover will give you $50 for that.
