The objective of this work is to design and implement centralized RFID based National Identity card management system using embedded microcontroller. In this electronics projects, the use of RFID (Radio Frequency Identification) technology can be employed for not only bringing down the costs but also facilitate automating and streamlining applicant identification processes in the following systems – Medical information , Passport Information Driving License Ration Card Information Voter ID Information.. The system implements an RFID reader interfaced with an embedded microcontroller to PC. The RFID system manages the details of the applicant like name, address, personal details, business/academic details etc for all the following applications Medical information, Passport Information Driving License Ration Card Information Voter ID Information. By this way the user can maintain a single RFID tag for all possible applications.
