RFID Systems enable non-contact reading and writing of data. Also called
electronic tags, IC tags, ubiquitous ID systems, and RF tags, RFID Systems
enable non-contact reading and writing of data.
What is an ID System?
ID system stands for the Identification System. It is a system to read and
identify information on people and things, including AIDC (Automatic
Identification & Data Capture).
AIDC uses devices that combine hardware and software and does not require
human intervention to identify information obtained from media such as
barcodes, 2 dimensional codes, RFID systems, iris, fingerprints, voice
etc.
Barcode/2 Dimensional Code Applications
Barcodes are also known as linear symbols, and 2 dimensional codes are
also known as 2 dimensional symbols. Barcodes are attached to food and
commodity in a variety of industries such as retailers, distributors,
logistics company where the automation has been introduced.
Meanwhile, 2 dimensional codes have become common to catch up with the
expansion of information control as well as to save space.
RFID System Applications
RFID System is an abbreviation of Radio Frequency Identification System.
It is an "Identification system using wireless communication" that enables
transferring data between "RF Tags (or Data Carriers)" that are held by
men or attached to objects and "Antenna (or Reader/Writers)". It is a kind
of radio communication system.
Examples of such a system that may be familiar include the "electronic
ticketing system at train stations" and "touchless gate system on ski
lifts".
In these examples, tickets or lift passes are RF tags and the ticket gate
or ski lift is an antenna.
Such systems are also used for the automatic payment in food halls. In
this case, every food item has an RF tag attached to it, and an antenna is
inside the table on which the food tray is placed when making payment.
This makes it possible to not only automatically calculate the price of
the food, but also automatically display information such as total
calories.
Recently, this kind of system has gained a lot of attention to realize a
ubiquitous society.
What is an RFID System?
An RFID system makes it possible to read and write data without contact,
using electromagnetic or electric waves. Information can be read
irrespective of the quality or surface condition of the item to be read.
The large communication area helps to achieve high reliability in
communication. The implementation of a RFID makes it possible to "unite
items with their information", which allows for the creation of a highly
flexible and highly reliable system.
Definition of "RFID" by Japan Automatic Identification Systems Association
(JAISA)
1. Portable size
2. Information is recorded on an electronic circuit
3. Contactless transmission is performed
JIS Definition of "RFID"
A generic name for a device where data is read and written in a
semiconductor memory with contactless transmission over short distances,
using inductive electromagnetic field or waves.
