25th Anniversary of the QR Code : Special website on the development story of the QR Code and its 25-year history launches.


DENSO WAVE Incorporated (head office: Agui, Chita, Aichi; Chairperson of the Board and CEO: Katsuhiko Sugito) today announced its commemoration of the 25th anniversary of its QR Code. In 1994, the QR Code was developed to reduce the inconvenience of barcode reading for the company’s manufacturing personnel. The QR Code is designed to read a large amount of information efficiently, and is intended to be used freely by people around the world. With its open patents and specifications, the QR Code is now widely used worldwide.

■ DENSO WAVE’s vision expressed in the title of the special website “The Future Has Just Begun ”

DENSO WAVE’s 25-year-old QR Code is now used in many fields including business, daily life, and medicine. It is also a key technology for cashless payment which is becoming the norm worldwide. By scanning a QR Code with a smartphone, it is possible to access needed information, obtain coupons, purchase an airline ticket without standing in line, and do cashless shopping. The widespread use of the QR Code has made many previously impossible things possible; it is simple, convenient and fun to use.
DENSO WAVE will keep working to create a safer, brighter future, believing in the unlimited potential of this tiny square code.

■Views of the developer of the QR Code

When I worked in the section that developed barcode readers and optical character readers (OCRs), the automotive, electrical, and electronic industries used barcodes which could only hold about 20 alphanumeric characters. Barcodes contain a limited amount of information and can easily become difficult to read due to dirt or stains, and were becoming inadequate for managing parts and products in manufacturing sites. The QR Code was developed to overcome the disadvantages of the barcode.
The QR Code can store up to about 7,000 characters and is now used globally, especially as a key technology for cashless payment.
I was determined to develop a world-class two-dimensional code, and it gives me great pleasure that the QR Code is recognized worldwide and is used more widely than I had expected. New types of IT technology will continue to emerge. DENSO WAVE will improve the QR Code to help create a new future.
