RFID is emerging as an important technology for revolutionizing a wide range of applications, including supply-chain management, retail sales and healthcare

Predictions indicate that RFID will be worth billions of dollars in new investments. According to IDTechEx, the RFID market will increase from US$4.96 billion in 2007 to US$26.88billion in 2017

RFID is Radio-frequency identification precisely used for identifying objects What is RFID? RFID uses radio-frequency waves to transfer identifying information between tagged objects and readers without line of sight (LOS), providing a means of automatic identification Abdullah Al Mahmud, 0507006, Dept of CSE, KUET, Bangladesh

Components of RFID systems A typical RFID system consists of: Transponder or Tag Interrogator or Reader A computer network Abdullah Al Mahmud, 0507006, Dept of CSE, KUET, Bangladesh

A typical RFID system consists of:

Transponder or Tag

Interrogator or Reader

A computer network

A tag contains a chip that stores the identifying information of the object or person to which it is attached and an antenna that communicates the information via radio waves. System Basics: The Tags Abdullah Al Mahmud, 0507006, Dept of CSE, KUET, Bangladesh

A tag contains a chip that stores the identifying information of the object or person to which it is attached and an antenna that communicates the information via radio waves.

System Basics: The Readers When a tag passes through an RF field that a reader generates, the tag transmits that information to reader and identify that object or person Readers (interrogators) can be at a fixed point such as Entrance/exit Point of sale Warehouse Abdullah Al Mahmud, 0507006, Dept of CSE, KUET, Bangladesh
