Basics: (Source: Wikipedia)
Radio-frequency identification (RFID) is an automatic identificationmethod, relying on storing and remotely retrieving data using devices called RFID tags or transponders.
An RFID tag is an object that can be applied to or incorporated into a product, animal, or person for the purpose of identification using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.
Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a (RF) signal, and other specialized functions. The second is an antenna for receiving and transmitting the signal. Chipless RFID allows for discrete identification of tags without an integrated circuit, thereby allowing tags to be printed directly onto assets at a lower cost than traditional tags.
Application:
Automation plays an important role in Industries. Apart from this, Automation has also made the domestic life easier. There are lots of advantages like saving man power, higher accuracy in work; quick process etc. apart from this automation also leads to the technological improvement of the country. The developing as well as developed countries needs technology not only in industries also in domestic life. The safety systems in home, automation in home also plays a big role in countries development towards technology. In this project, RFID technology is used for automating the public distribution of sugar, rice, kerosene etc. It is completely safe and secured way of delivering food stuffs to the people who get it through PDS. In particular in developing countries, 90% of the people depending on PDS for getting their goods like rice, wheat, sugar, kerosene etc. It is purely a society oriented project which helps the people to get right amount of commodities from the Ration shop.
