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.
