You can get prepaid credit cards now

One that comes to mind is the Virgin one. There is no way possible to get into any debt because of them as you can only spend what money you put onto it. The virgin one I know you can also buy people as a sort of "gift card" It's what I bought my little sister instead of buying her something random I charge her card and she goes off shopping.

They are very cheap and usually only have a small service charge. I think they seriously are great ideas for kids that aren't able to use their parents credit cards.
