Abstract :
A taximeter smart sensor system possessing immunity to fraud is introduced. The system is based upon embedded controllers employed to perform the crypto-operation between the sensor and taximeter using the standard RC5 algorithm. Special emphasis is given to promote highest system integrity while keeping complexity, size and cost to minimum. Preliminary practical implementation and verification of the system installed and tested under real taxicab environment promises its feasibility to cope with fraud in processing taxi fares.
