The QR code was invented in Japan in 1994 by a development team led by Masahiro Hara for the Denso Wave company. The team was tasked with developing a barcode that makes it easy to track cars and car parts during manufacturing. Today, these codes have various uses across industries such as retail, marketing, packaging, and logistics.
QR codes were designed to be quickly and easily read by readers, and soon became popular outside of the automotive industry as a tool for inventory tracking and product information.
QR codes can store various types of data, including contact information, text URLs, and even GPS coordinates. They can also be used to trigger actions on the phone, such as opening a website or downloading an app. QR codes have evolved over the years and now you can even pay with them.
The higher the resolution of a QR code, the more data it can store. The smallest and oldest resolution is a 21×21 pixel matrix, while version 40 of the QR code can have a resolution of up to 177×177 pixels and thus provide up to 1852 characters of data. Currently, version 10, with a resolution of 57×57 pixels, is the most common type of QR code you will find.
The systems follow the data pixel by pixel to encode and decode. Since QR codes can only contain black and white pixels, each pixel can be represented as one bit. Patterns are used in the data to make it easier for scanners to read the QR code so they know when it has reached the end of a line or if there is an error.
QR codes were widely used in the early 2000s because they can store information in a small space. QR code scanners were developed for phones and other mobile devices so people could quickly scan them and access information on the go. These codes have various uses across industries such as retail, marketing, and logistics.
