Using fuel cards is a first step in controlling expenses, but without telematics integration, their potential is limited and fraud is easy.

The real power comes from automatic data reconciliation.

When a purchase is made with a fuel card, the transaction (amount, volume, gas station location, time) is sent to the fleet management platform.

The system then instantly compares this information with data from the telematics device of the vehicle assigned to that card: 1.

**Presence Validation:** The system verifies if the vehicle was physically at the gas station at the time of the transaction.

If the card is used in Paris while the vehicle is in Lyon, a fraud alert is immediately triggered.

2.

**Tank Validation:** For vehicles with CAN Bus access, the system can compare the volume of fuel purchased with the actual increase in the tank level.

If 80 liters are billed but the tank only increased by 60, it may indicate theft.

3.

**Consumption Analysis:** The system can detect inconsistencies, such as a sudden spike in consumption per kilometer, suggesting siphoning.

This integration transforms a simple payment card into a robust control tool, virtually eliminating the risk of misuse (e.

g.

, filling up a personal vehicle) and providing unparalleled fuel cost data accuracy for TCO calculation.
