What is RFID System?
RFID system is a non-contact ID system which can read and write data on a
tag via radio waves or electromagnetic waves. It consists of a tag (data
carrier, ID card) which stores data, an antenna which communicates with
the tag, a controller which controls the antenna, and higher-level
equipment (system) which controls the controller.
Communication methods between the tag and the antenna include a microwave
type using radio waves, and an electromagnetic inductive coupling type
applying the electromagnetic principle (transformer principle).
Features of RFID are:
(1) Non-contact data communication is possible.
(2) Reading and writing of data is possible.
(3) Having a capacity enough to record more information than
(4) Small enough to carry around or to use by attaching on an object
RFID stands for Radio Frequency Indication System, and is commonly called
Wireless ID System, Wireless IC Tag, FA-ID and Auto-ID.
As can be expected from its common names, the RFID system has two origins:
one is consumer/social system developed from the IC card, and the other is
industrial ID system as typified by the barcode system, and then both
origins have been joined together, making the RFID one of the most
highlighted new technologies.
