Simulation of smart card interface with PIC for vehicle security system

This paper describes the design and the development of a prototype of an interfacing between PIC and smart card that is important in car security application. Smart card was used, as one of the cheaper way to prevent the car from robbery or theft. Each smart card supplied with machine ID that are set in the microcontrollerpsilas memory for authentication purposes. Here, the smart card function is similar to an external EEPROM chip; therefore for simplicity external EEPROM chip was used to replace the smart card. The software kits developed to help users to set an ID. Visual Basic 6.0 was used as interfacing with microcontroller chip 16F877A. Each registered user supplied with different smart cards of difference ID but with the same machine ID. This could be used in the system to ensure only the authenticated person can use the particular cars.
