Many things credit cards for bad credit
The company may also raise your interest rate by ten percent or more on the pretext that you've shown yourself to be a bad creditor and a credit risk. It doesn't matter that you have plenty of money in the bank and just forgot to put the check in the mail because of midterms. The fine print on the back of the agreement you signed with the company gives the company permission to do it, and they'll take advantage of it. So pay your bills for student credit cards a few days early, and arrange for automatic payments if you can. If you realize you're going to be late, call the company immediately and see if you can make a rush payment.
