What is a QR Code?
A QR Code (or Quick Response Code) is a type of two-dimensional barcode that is widely used for product/service tracking, item identification, time tracking, document management, general marketing, and much more. It is also used to store data and share it with other devices in a few seconds.

A QR Code is composed of a series of black and white squares that contain encoded information. It is created using a two-dimensional matrix barcode, which is a type of code that can be scanned by devices such as smartphones and tablets.
