What is QR code?

What is QR code? It was invented in 1994 by the Japanese company Denso Wave as a way to track automobile parts during manufacturing, but has since become widely used in many other applications.

A QR code consists of a pattern of black squares and rectangles on a white background, arranged in a square grid. The code can encode a variety of information types, including website URLs, contact information, calendar events, email addresses, and more. When scanned, the code is decoded by a QR code reader app, which then performs the associated action, such as opening a website or adding a contact to your address book. QR codes can be generated and printed on a variety of materials, including posters, business cards, and product packaging.
