Examples of IT standardization
The following are examples of standardization in IT.
Reference
Barcode
A “barcode” is an identifier that uses
bars and spaces of varying widths to
represent numbers and characters. A
barcode is a one-dimensional code in
which data is only read in a horizontal
direction.
Reference
JAN (Japan Article Number)
code
Abbreviation for “Japan Article Number”
code. There is a standard 13-digit version and a shortened 8-digit version.
Reference
QR (Quick Response) code
Abbreviation for “Quick Response
code.”
●JAN (Japan Article Numbering) code
The “JAN (Japan Article Numbering) code” is a JIS standard barcode
comprising 13 digits. From left to right, the JAN code comprises a 2-digit
country code, 5-digit manufacturer code, 5-digit product code, and single
digit check code. JAN code is commonly used today at the cash registers
of retail stores such as supermarkets and convenience stores, and is printed
on all kinds of product packages.
The JAN code is simply passed over a barcode reader to input the product
name and price at the cash register.
Below the barcode is a numbered code. If the barcode cannot be read, the
numbered code can be manually entered using a keyboard.

●QR (Quick Response) code
A “QR (Quick Response) code” is a JIS standard two-dimensional code.
While a barcode can only read information in the horizontal direction, the
QR code contains information in both the horizontal and vertical directions, enabling the code to hold more information than a barcode. A QR
code is also referred to as a “two-dimensional barcode symbology.”
The QR code contains a cutout symbol on three corners to enable quick
and accurate reading in any 360 degree direction.
