A land vehicle mileage measuring system 1 comprises a processor 2, clock 5, movement sensor 6, memory 10, battery 9 and anti-tamper sensor 8 all enclosed in a housing 7. In operation the processor 2 processes mileage data and signals from the clock 5 and movement sensor 6, encrypts the resulting data and stores it in the memory 10. The system allows mileage to be securely sensed and recorded and provides assurance that the stored data has not been tampered with. |
