I do have a true virtual creditcard as a free service through my bank, which is a program that generates a code which is vailed for the period you specify, can be a month or a year. It can be closed at anytime. You also specefy the balance that number should have and the "e-store" can not charge more then 5% extra of the specified ammount. It's great! Never had any problems and I've been using it for 3 - 4 years now
