This rule enforces daily velocity limits on individual card usage to prevent large-scale fraud when cards are compromised.

System alerts when card accumulates:
EITHER:
1. Total daily transaction volume of AED 100,000 or more
OR:
2. Alternative threshold of AED 200,000 (category-specific)

Daily limits are critical controls because:
- Compromised cards can process multiple transactions before owner notices
- Fraudsters often "max out" stolen cards within 24 hours
- Early detection limits total fraud exposure
- Prevents total account drainage before cardholder intervention
- Reduces chargeback liability for acquiring bank

Alert generated (not auto-HOLD) to enable:
- Real-time fraud analyst review
- Cardholder contact if pattern suspicious
- Velocity monitoring to catch fraud early
- Can escalate to card blocking if confirmed fraudulent
- Balances fraud prevention with legitimate high-volume customer needs
