This rule detects abnormally rapid transaction processing at a single terminal, which is physically impossible for normal customer activity.

The system flags when:
1. A terminal processes transactions with an elapsed time of 2 minutes or less between them
2. Each of these rapid transactions is AED 500 or higher
3. The same terminal shows this pattern repeatedly

This velocity is impossible for legitimate card-present transactions due to physical constraints (card insertion, PIN entry, receipt printing). Such patterns indicate automated fraud tools, compromised terminals running batch transactions, or card skimming operations. Transactions are immediately placed on HOLD.
