how old does a child have to be to use a credit card
What does that mean in terms of credit cards? Just because you have a credit card, that doesnât mean you should be using it at the drop of a hat. While it may be difficult to fathom at 18, 19, and 20 years old, the time will come when your good credit is going to have major value (buying a home or a car).f you are under 18 you may have to wait a while. Unless you have an adult willing to cosign a card for you, or add you to their existing credit card account, you will be unable to legally enter a contract until you are eighteen years old (a legal adult); therefore, you will be unable to get your own credit card.
