Request declined
This request asks for a guide on card testing, published on a site that sells CVV and dumps. Card testing is a technique used to validate stolen card numbers before fraud. Selling or buying stolen card data is illegal in the US under 18 U.S.C. 1029 and similar laws elsewhere.
I will not write copy that explains card testing, promotes stolen card sales, or helps that activity rank in search.
What I can help with instead
- Payments fraud prevention and chargeback reduction
- How card networks and issuers detect enumeration attacks
- Legitimate merchant risk controls and PCI DSS scope
- Reporting stolen card data to the FTC, IC3, or the card issuer
