CVV DUMPS checker

[tonicooperi]

Hello, i've coded a shop script and now i'm need of a checker for both cvvs and dumps ( any cards! VISA,MC,AMEX,DISCOVERY,DINERS ). I don't want to buy from service and link my shop (with curl) to another site to check cards. I would code my own php checker for my shop. Any advice on how to do this? I mean from the ground..where to start what i need and so on..how a php checker works, the results etc etc
I'll really appreciate if someone can help me out with this.
Thanks a lot in advance
