What is a QR code?

Created on 28 July, 2022FAQ

A QR code, an abbreviation for Quick Response code, is a type of two-dimensional barcode. It is characterized by black square modules arranged in a square grid against a white background. The configuration of these modules encapsulates the information stored within the code. This machine-readable optical label can be displayed on a mobile device's screen or physically printed on paper.

While the QR code is one of the most recognizable formats, there are other two-dimensional barcode formats that function similarly. These include Flashcode and 2D-Doc, which are often mistakenly referred to as QR codes due to their visual similarity. Despite the confusion, each barcode format has its distinct characteristics and applications.
