ABSTRACT
Here we describe a system to identify a person based on their finger print. The people able for voting store their finger print in the system EEPROM by the authorities. When any one tries to enter by putting their finger in the module, the system first scan the finger inserted and compare the finger prints stored in the system memory. If the finger print does not match with the new entry the voting will not be allowed. If it matches with any one of finger print pre stored the system allows entry.
The system is built around the popular MICROCONTROLER PIC 16F 877A. The microcontroller does the all control operation to read, compare and to control the other circuits. The system has a key board and an LCD display to see the status of operation. Using the key board we can add new finger prints when required. The system gives indication through an audible and visual means for operation status and also alarm when the person is unauthorized. We use finger print module from SUN ROM technologies which in built scanner, processor and memory to store finger templates also
The polled votes are stored in EEPROM. This EEPROM data is accessed after polling completed for publishing the results.
