Depends on your location: where are you from? If you are from the US there are cards like the netspend visa card for example. Please let me know
I have my own visa credit card. but I want to pay somewhere anon with visa prepaid. I don`t need physical virtual prepaid visa is suit for me.
Try http://www.ikobo.com , They are reliable. But the only problem is, you have to transfer money from another CC or bank account to ikobo card.
