In this project, first step is to design GSM based FPS tracking system. Thumb detector is interfaced to AT89s52. This thumb detector is used to match the fingerprint of valid customer. AT89s52 is used to store the information related to customer and GSM module is used to send the message to the higher authority. The power supply circuit is built to provide the required supply voltage to the circuit. The 7 Segment LCD display is used to display the user related information on the LCD display.
