In this project we will make voting machine using fingerprint machine. We will use fingerprint module for this purpose is sim630. There will be keys for any data store and check vote casted by anybody.
In this project we will use finger print module to recognize person. After recognition it will give data to Microcontroller 89s52. Finger print is the better option as compare to other. Normally we recognize person with password or some other method. It’s the best security system. It helps to find out person identity and will display on LCD. We will use serial interface for communication between finger print module and Microcontroller . few commands required to communicate search database from module. Module itself programmed with ARM processor. Module also have fixed memory. So you don’t require external serial or parallel interface for memory. We will use push to on switches to enter data. First of all we will add our thumb expressions. If all added, then there will be switch to search all. We will also use a key to delete all finger prints.
Applications:
Electronics voting machine
Access control using person recognition
Attendance system
