You need a card with a fixed interest rate
If you are going to be shopping around for student credit cards soon, you should try and find a card that is offered with a fixed interest rate. I’m not at all in favor of a variable interest rate credit card — that’s because, under certain circumstances, the interest rate can balloon out of control. Young people have enough distractions and difficulties when it comes to managing their finances and controlling their use of credit — you don’t want to compound the problem by giving them a credit card that will have a constantly changing rate of interest, do you?
