Hey, I have a prepaid credit card. You put money in it and that's all you can spend, It's a 3V card, got it on www.3v.ie I was wondering if anyone knew any similar cards in America as someone I know from the states would like one.

Thanks in advance.

maybe you should also try an secured credit card. Where prepay the money on the card while also building your credit all of the major banks have one. Bank of America, Wachovia.

What you call a prepaid credit card is actually a secured credit card, I guess. A prepaid card is a sort of debit card, when you put money on a card account and then you can spend it without carrying cash.
As for secured credit card, it is not pre-paid, as you do not use the money you install. You secure your credit with your own money, this makes the bank feel free to issue some credit to you. In case you will not be able to pay off, the bank has a right to take the money you installed.
At the site I work at, the most popular secured credit cards are by First Premier and Orchard bank.
