A QR code (Quick Response code) is a two-dimensional barcode or machine-readable optical label used to store detailed information. QR codes store data using patterns of dots and spaces, arranged in a grid. These patterns can be scanned and translated into human readable information using an imaging device like a camera. QR codes are easy to generate and are a convenient way to store all kinds of data in a very small space! For example, if the data you want to store in a QR code is made of only alphanumeric characters, a single QR code can hold up to 4000 characters. Each QR code has built in error correction capability to restore data if the code is dirty or damaged.
