Well, if you look at your screen. There is a generator under the validation checker.
You're welcome

I see. There is a FAKE generator. It doesn't generate the PIN / Security Code of the VCC so no one can use it at all. My generator have generate all information of the vcc and it's 100% legit. Im not sure if it only generate valid card numbers. But as far as i can see, it only generate fake vcc or a fraud one. Just correct me if i'm wrong.
If you say so. I even made a Screenshot to let people see:

Also, sites check if the cards are valid through the same algorithm they were generated and will not know if they have balance or not. Either it's valid, or not.
You can use these cards to verify any site you want, that don't charge a small verification charge of about 1-2$.
