Which internet game cards are available?

Hi people, I really hope I can get some answers to my problem, because I have been having it for quite a while. The thing is: I want to buy some sort of card like Ukash, which has some kind of code, that i can use on the internet, so that my account has got the amount of money on it so I can buy things for online games, or such thing alike. I've been paying for something that I need €5/month for, but I don't want my parents to see money going off my bank account, so I can't buy it through that. I've tried making money online, but I just failed in that. Anyone has an idea if there are other sorts of cards, or any other method that could make me solve my problem? Kind regards, C*
