ABSTRACT:
In this project we show that, how we design a new idea for UID code. As a UID code when any person show its card to the reader, then reader gets the data from the RF passive card and this data is to be compared with the internal data base. This data base is then displayed on the LCD display. This database can then be used for a variety of identification purposes. This system will help in tracking their citizens, permanent residents, and temporary residents for the purposes of work, taxation, government benefits, health care, and other governmentally-related functions.
INTRODUCTION
In this project we are trying to create and manage a centralized identification system for all citizens and residents, which can be utilized for a variety of identification purposes. This system will help in tracking their citizens, permanent residents, and temporary residents for the purposes of work, taxation, government benefits, health care, and other governmentally-related functions. The ID is fundamentally being prepared to identify Indian citizens so that better security can be provided by identifying illegal immigrants and terrorists. However, the real power of the ID is in its ability to provide ease of identity establishment to Indian citizens when accessing a variety of governmental and private-sector services. As the unique identity database comes into existence, the various identity databases (voter ID, passports, ration cards, licenses, fishing permits, border area id cards) that already exist can be linked to it.
The likely benefits of the new ID system to the citizens will be as below:
1) Subsidies on food, energy, education, etc to people who are entitled to receive them.
2) Opening bank accounts
3) Getting new telephone, mobile or internet connections,
4) New light or gas connections
5) Getting a passport
6) The same card may act as a driving license and store your traffic violation records
7) It may act as your electoral card
8) Family genealogy may be traced.
TAG
For this type of system we employ digital data system for every individual. We insert the digital database in the card. The card or ‘TAG’ consists of a silicon device and antenna circuit. The purpose of the antenna circuit is to induce an energizing signal and to send a modulated RF signal. The read range of tag largely depends upon the antenna circuit and size. The antenna circuit of tag is made of LC resonant circuit or E-field dipole antenna, depending on the carrier frequency. The LC resonant circuit is used for the frequency of less than 100 MHz. In this frequency band, the communication between the reader and tag takes place with magnetic coupling between the two antennas through the magnetic field. The card will store all the information about an individual
READER
The information from the TAG is read by the reader, the reader includes RF transmission, receiving and data decoding sections. The RF transmission section includes an RF carrier generator, antenna and a tuning circuit. The RF transmission section includes an RF carrier generator, antenna and a tuning circuit. Typical, reader is a read only device, while the reader for read and write device is often called interrogator.
ENCODING
Data encoding refers to processing or altering the data bit stream in-between the time it is retrieved from the RFID chip’s data array and its transmission back to the reader.
THEORY OF OPERATION
What is RFID?
RFID stands for Radio-Frequency Identification. The acronym refers to small electronic devices that consist of a small chip and an antenna. The chip typically is capable of carrying 2,000 bytes of data or less.
The RFID device serves the same purpose as a bar code or a magnetic strip on the back of a credit card or ATM card; it provides a unique identifier for that object. And, just as a bar code or magnetic strip must be scanned to get the information, the RFID device must be scanned to retrieve the identifying information.
RFID Works Better Than Barcodes
A significant advantage of RFID devices over the others mentioned above is that the RFID device does not need to be positioned precisely relative to the scanner. We're all familiar with the difficulty that store checkout clerks sometimes have in making sure that a barcode can be read. And obviously, credit cards and ATM cards must be swiped through a special reader.
In contrast, RFID devices will work within a few feet (up to 20 feet for high-frequency devices) of the scanner. For example, you could just put all of your groceries or purchases in a bag, and set the bag on the scanner. It would be able to query all of the RFID devices and total your purchase immediately.
