All sellers must complete identity verification including government ID, address confirmation, and phone verification. Business sellers must provide additional documentation like business licenses. We also continuously monitor seller performance and conduct periodic re-verification.

If you receive a counterfeit card, report it immediately. We'll investigate with our authentication experts, and if confirmed, you'll receive a full refund plus return shipping costs. The seller will be permanently banned and we'll work with law enforcement if necessary.

We use bank-level encryption and are PCI DSS compliant. Your payment information is never stored on our servers - it's processed securely through our payment partners. All transactions are monitored for fraud in real-time.

All shipments are tracked and insured. If your package is lost or damaged, we'll work with the shipping carrier to resolve the issue. You're covered by our buyer protection program and will receive a full refund or replacement if the issue can't be resolved.

Our AI system automatically detects potential duplicates using image recognition and card details. All listings go through expert review before going live. We also have a collaborative system where multiple sellers can join existing recognition jobs instead of creating duplicates.
