Giving your teenager a credit card may seem like a scary proposition, but it could be the safest way to teach them about credit. Credit expert John Ulzheimer says it's just like teaching your teenager how to operate a car, but in a controlled environment. “Nobody would just let a teen hop in a car and drive,” says Ulzheimer, who formerly worked with Equifax and FICO. “And nobody should just let their kid get a card on their own someday without some teaching by the parents.”
