Radio Frequency Identification (RFID)

Radio Frequency Identification Radio Frequency Identification or RFID in short is essentially an enabling technology. The unique advantage of RFID is that it eliminates the requirement of human intervention thus providing immense business value.

RFID is a generic term that is used for describing system which transmits identity of a person or an object or even an animal wirelessly by making use of radio waves. A typical RFID system has 3 components, an antenna, a transceiver (it reads the radio frequency and subsequently transfers the information to a processing device) and a transponder or RF tag (containing RF circuitry and the information for transmission).

One of the most popular applications of RFID is in tracking assets. A wide range of RFID system is used for an effective asset management programme. In India, you will see very soon RFID intervention being used extensively. Neighbourhood Post offices using RFID to track lost parcels, Indian farmers keeping a tab on their cattle using RFID, these are two small examples of massive RFID deployment.

Other applications include legal firms turning to RFID for tracking or automating files, airlines use the technology to track the location of luggage trolleys, construction companies using RFID tags inserted to concrete blocks for instant dissemination of results over the internet. RFID results in saving of a lot of wasteful expenditure and reduces the chances of human error. It is now increasingly used by industry as an effective alternative to the bar code.

Department of Information Technology has its focus on the R&D areas of RFID and providing RFID based techno solutions to the Indian industries. With this objective, the ambitious "National RFID Program" project was initiated in April, 2007. The program is being implemented jointly by IIT, Kanpur, C-DAC, Noida and SAMEER, Mumbai. The major highlights of the project are software/hardware development, middleware integration and development of end-to-end solutions. Research component is mainly undertaken by IIT Kanpur, application development including deployment and support is provided by C-DAC, Noida while SAMEER Mumbai is focused primarily on RFID antenna design and other RF related issues. C-DAC and IIT, Kanpur will also undertake RFID related manpower development programs.

Presently, C-DAC, Noida is in the final stages of developing and testing pilot project of Parcel Tracking System for Department of Posts. The pilot will be implemented at select Speed Post Centers in some cities. The software will be later integrated with the existing Speed-Net software of Department of Posts and the system will be scaled up at other Speed Post Centers.

SAMEER has provided technical support to CDAC in field trials in terms of RF characterization/modifications. These include characterization of RFID System, providing technical assistance in field trials, designing of Reader Antenna for Gen II Tags, Linear Polarized Planar Antennas and Circular Polarized Antennas and developing RFID System Using Zigbee Modules.
