Fraud Detection Red Flags
Real-Time Rules (Automated Screening)
High-risk signals (block 70% of fraud, 2% false positive):
- Velocity: Same card used 3+ times in 10 minutes
- Geolocation mismatch: Card location ≠ shipping address distance >500 miles
- Device fingerprint: New device after 10 trusted transactions
- Amount spike: Purchase 5x higher than customer average
- Shipping address: Known fraud hotspot (certain postal codes)
- CVV bypass: Customer submits payment without CVV when required
- Time anomaly: Purchase at 3am for account that usually buys at 2pm
Manual Review Rules (High precision, catch remaining 30% fraud):
- Shipping address = PO box or package forwarding service
- Multiple failed payment attempts followed by success
- High-value order from new account with no email verification
- Customer uses VPN/proxy IP (detected by IP geolocation mismatch)
- Billing address is USA, shipping is USA, but phone is international
Chargeback Management
The Chargeback Cycle (2026 Timeline)
| Day | Action |
|---|---|
| 0 | Customer disputes charge with their bank |
| 10 | Merchant receives notification + temporary debit |
| 30 | Merchant has 7 days to submit evidence |
| 45 | Bank makes final decision (merchant vs. cardholder) |
Outcomes:
- Merchant wins (45% rate): Chargeback reversed, funds restored
- Cardholder wins (50%): Merchant loses $$ + chargeback fee
- Partial reversal (5%): Partial refund issued
