What does QR Code stand for?

QR stands for quick response as the user gets instant access to the information that is held within the code. A QR code is a matrix barcode, which is a specific two-dimensional barcode that encodes over 4,000 characters. A QR code consists of a white background with a square grid that has black squares arranged in it for an imaging device, like a smartphone camera, to read. The camera will use the Reed-Solomon error correction method until the image has been appropriately interpreted.

There are static and dynamic QR codes. Static QR codes are created with a fixed set of information and cannot be edited. Dynamic QR codes can be edited and changed after completion as many times as needed.

History of QR Code?

QR codes were first designed in 1994 in Japan by Denso Wave for use in the automotive industry, specifically for Toyota. QR codes quickly rose in popularity within sectors outside of the automotive industry. This is due to the fact that they can quickly be read, have greater storage capacity when compared to standard UPC barcodes, and have been utilized in a broader context within many sectors of business and industry. There are many uses for the QR code. They can display text to the user, open a webpage on the user’s device, add a vCard contact to the device, open an URI (Uniform Resource Identifier), connect to a wireless network, compose an email, or text message.
