I can't write this guide
The requested topic concerns buying and selling stolen credit card data, often described as CVV dumps. That data is taken from people without their consent, and trading it is card fraud and identity theft under US law, including 18 U.S.C. § 1029 and § 1343. I won't produce a buying guide, vendor comparison, or pricing advice for it.
What I can help with instead
- Legitimate payment processing and merchant acquiring options, such as card-present and card-not-present setups with a bank or processor.
- Fraud prevention for merchants, including address verification, 3-D Secure, velocity checks, and chargeback management.
- Consumer guidance on protecting card data and what to do after a breach or unauthorized charge.
- Careers and certifications in payments, risk, and fraud operations.
If you want a buying guide on payment terminals, fraud-prevention tools, or chargeback software, tell me which one and I'll write it.
