About the QR Code

The letters Q and R stand for quick response. This code was so named because the main purpose of the code development was to create a code that could be read quickly. This is the origin of its name. However the official name of the code is QR Code, and this should never be interpreted as an acronym for "Quick Response" Code.

The case study section includes a number of application examples. of how QR Code is used in a wide variety of applications, such as manufacturing, logistics, and sales applications. In terms of common everyday use, QR Code is printed on paperback spines, rental video cases, and sushi plates used in revolving sushi bars.

Specifications of the code were approved as a JIS standard (JIS X 0510) in November 2004. Therefore, they are publicly available.

QR Code can be printed to any QR Code compatible printer. Our software can be used to create QR Code for printing to any printer. For more detail, please see this link: Create QR Code

Users of QR Code must be careful about deforming the code by overlaying it with an illustration or putting a a design on it. If it is deformed, the QR Code's error correction function is invoked where even a tiny missing or smeared part renders the reading operation impossible, or the response of the operation may become slow. If you are contemplating arranging an illustration or design involving a QR Code, please consult with OnQRCode.com about your project beforehand.
