Valid credit card generator?
It's impossible to generate a valid credit card.
Well on the internet there are thousands of fake credit card genrator, but they generate invalid credit card numbers, and you cannot buy anything with them.
Go and get a real credit card, or steal someone's, or something...
All those programs are always going to eat crappy crap. All useless. Don't trust them. Most are viruses. Why not visit a site that offers things for free and is legal? sourceforge.com, incompetech.com, all those will. Just Google them.
