FTC 2025 data logged 1.2M unauthorized charge reports, costing $8.8B. Mini case study: Jane saw a $500 charge on her statement. Bank dismissed it initially, but her annotated statement with descriptor match and merchant email proved legitimacy, resolving in 7 days.
Types of Primary Evidence
Primary evidence includes tangible proofs accepted in 80% of initial disputes (Visa 2026 stats):
- Statement annotations verifying credit card charge: Highlighted entries with merchant name, date, amount, and descriptor. Reliability: 90% acceptance if matched to merchant records.
- Receipts proving credit card payment validity: Physical/digital receipts with card last-4, signature/PIN, and timestamp. Pair with statements for 95% dispute wins.

- Verify timestamps align within seconds.
- Obtain authorization code from processor.
This resolves 75% of merchant disputes pre-chargeback.
Digital and Forensic Evidence
Advanced proofs like forensic analysis credit card transaction logs reconstruct events via processor data. Digital timestamps evidence credit card fraud use UTC stamps for sequence verification. IP logs tracing credit card charge origin pinpoint devices/locations.
2026 updates: Tools like Visa's Decision Intelligence mandate IP submission. Mini case study: IP trace from U.S. bank to Nigerian server resolved $10K international fraud, overturning chargeback via geolocation mismatch.

|---|---|---|---|
| EMV Chip Data | Unique cryptogram proves legitimacy | Absent/mismatched indicates tampering | Requires processor access |
| PIN Verification | Confirms user consent | No record suggests bypass | Ineffective online |
| IP Logs | Matches user location | Foreign IP flags fraud | VPNs obscure |
| Descriptor Match | Aligns with merchant | Mismatch proves scam | Vague descriptors common |
| CCTV | Visual link to cardholder | No footage supports theft claim | Privacy laws limit use |
