RFID technology and its applications in Internet of Things (IoT)

TLDR

Radio frequency identification (RFID) uses radio waves to automatically identify and track objects, and when integrated with the Internet of Things (IoT) it enables global, real‑time monitoring, making RFID a foundational technology for IoT. This paper introduces RFID and IoT technologies, discusses their applications, and examines challenges of using RFID within IoT.

Abstract

Radio frequency identification system (RFID) is an automatic technology and aids machines or computers to identify objects, record metadata or control individual target through radio waves. Connecting RFID reader to the terminal of Internet, the readers can identify, track and monitor the objects attached with tags globally, automatically, and in real time, if needed. This is the so-called Internet of Things (IoT). RFID is often seen as a prerequisite for the IoT. This paper introduces the technologies of RFID and IoT, discusses the applications and challenges of RFID technology used in IoT.
