RADIO FREQUENCY IDENTIFICATION

RADIO FREQUENCY IDENTIFICATION

ABSTRACT:

Radio Frequency IDentification (RFID). RFID tags are small integrated circuits connected to an antenna, which can respond to an interrogating RF signal with simple identifying information, or with more complex signals depending on the size of the IC.RFID use a semiconductor in a tag or label to transmit stored data when the tag or label is exposed to radio waves of the correct frequency.

It has variety of applications in several areas like:

-Library management.
-Traffic control.
-Human and animal identification.
-In hospitals
-Supply Chain Management.

Any application of RFID needs to result in obvious business benefits. The last few years have seen several developments that have sped up the adoption of this technology. The emergence of major consumer applications that bring RFID from an experimental technology into the mainstream. As it gains understanding and credibility through highly visible consumer applications that prove its effectiveness, its place as a solution in
supply chain automation also grows.

This paper include basic concept of RFID-what is RFID? need of RFID, components of RFID, architecture of RFID.
We are discussing supply chain management (SCM) as an application of RFID. We are describing complete implementation of SCM by using RFID.For this we describe a seven-layer reference model, which can be use for implementation of supply chain management.

At the end we discuss benefits and pitfalls of RFID.
This paper includes both theoretical information about RFID and real life application profiles—all intended to make clear how the technology can be applied successfully.
