About RFID Handbook: Technology, Applications, Security

Radio Frequency Identification (RFID) is a technology which is at the centre of the revolution around Supply Chain and Retail industry. The book RFID Handbook: Technology, Applications, Security and Privacy gives a detailed breakdown of the entire RFID Architecture and components. We look at the parts which make an entire RFID implementation: RFID Tags, RFID Reader, RFID Antenna, Radio Frequency Scanners, Active/Passive RFID Technology and related Information Management System.This RFID handbook does a 360 degree overview on the numerous applications of RFID. There is also a detailed case study on RFID implementation at Walmart, which was one of the pioneers of RFID retail applications. Also included is parts of an RFID security system and an elaboration on privacy issues around RFID.IntroductionRadio frequency identification (RFID) is a general term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object wirelessly, using radio waves. RFID technologies are grouped under the more generic Automatic Identification(Auto ID) technologies.The barcode labels that triggered a revolution in identification systems a long time ago, are inadequate in an increasing number of cases. They are cheap but the stumbling block is their low storage capacity and the fact that they cannot be reprogrammed.A feasible solution was putting the data on silicon chips. The ideal situation is contactless transfer of data between the data carrying device and its reader. The power required to operate the electronic data carrying device would also be transferred from the reader using contactless technology. These procedures give RFID its name.One grand commercial vision for RFID is to change the way demand-supply chain moves. In the current almost stone-age scenario, manufacturer produces goods based on forecasts and hopes all of them will be consumed before the shelf life gets them.
