The book consists of a collection of works on utilising the automatic identification technology provided by Radio Frequency Identification (RFID) to address the problems of global counterfeiting of goods. The book presents current research, directed to securing supply chains against the efforts of counterfeit operators, carried out at the Auto-ID Labs around the globe. The collection of works and the organisation of the book assume very little knowledge on the part of the reader on Networked RFID systems as the material provided in the introduction familiarises the reader with concepts, underlying principles and vulnerabilities of modern RFID systems. The collection of works presented on highlighting the counterfeiting problem and problems with existing low cost RFID technology is an important guide to practitioners, professionals and graduates in the area of RFID systems application, implementation and integration.
