What is EAS

The radio frequency idtentification (RFID) is a wireless technology that enable automatic identification and extraction of stored information from any tagged object within a supply chain environment. A simple RFID system uses radio waves to collect and transfer data from a tag attached to an object linked to an RFID reader for identifying, tracking, and data capturing. However, RFID-based systems have numerous security- and privacy-related threats for the deployment of such technology in supply chain automation purpose. This chapter explains the technical fundamentals of RFID systems and its security threats. It also classifies the existing security and privacy threats into those which target the RFID components such as the tag, the communication channel, and the overall system threats. Finally, the chapter discusses the open research challenges that need further investigation, especially with the rapid introduction of diverse RFID applications in supply chain management (SCM).
