RFID (Radio Frequency Identification) is used in all areas of automatic data capture allowing contactless identification of objects using RF. This reference on RFID technology and application, shows how RFID is set to be the major growth area in automatic identification in the near future with the biggest boom in supertag technology and anti-collision protocol. The Supertag is expected to replace the barcode as the dominant logistics auto ID technology. As a single source reference for ADC professionals, coverage spans frequency ranges and regulations, coding, data integrity, cryptography, and standards. For end-users, the text explains how RFID systems work with examples illustrating the broad applications, potential and benefits.
