The idea of the project is to add an RFID on every bike participating in race/rally and to setup microcontroller based RFID readers at several checkpoints along the route. The microcontroller boards will be equipped with RTC (real time clock) to keep the log of time and EEPROM to maintain log of cross timings for all the bikes.
Later the data from all such microcontroller units can be transferred to a centralized database via serial like provided with every microcontroller board. The computer software can then be used to generate lap records, time based maps, analysis reports, race results and more statistical/graphical results.
