What is QR code ?
A QR Code is a matrix code (two-dimenisional bar code) created by Japanese corporation Denso-Wave in 1994. The "QR" is derived from
"Quick Response", as the creator intended the code to allow its contents to be decoded at high speed. QR Codes are most common
in Japan, and are currently the most popular type of two dimensional code in Japan. Although initially used for tracking parts
in vehicle manufacturing, QR Codes are now used for inventory management in a wide variety of industries. More recently,
the inclusion of QR Code reading software on camera phones in Japan has led to a wide variety of new, consumer-oriented applications,
aimed at relieving the user of the tedious task of entering data into their mobile phone. QR Codes storing addresses and URLs are
becoming increasingly common in magazines and advertisements in Japan. The addition of QR Codes on business cards is also becoming common,
greatly simplifying the task of entering the personal details of a new acquaintance into the address book of one's mobile phone.
The Japanese standard for QR Codes, JIS X 0510, was released in January of 1999, and a corresponding ISO International Standard, ISO/IEC18004,
was approved in June of 2000.
