I. Introduction
A quick response (QR) code is a machine-readable optical label that carries information about the associated item or product [1]. Barcodes encode information in just one vector. On the contrary, information in a two-dimensional code, such as the QR code, is coded in both horizontal and vertical directions. It is easy to read and can hold a big quantity of data. In 1994, Denso Wave Incorporated in Japan devised the QR code [2]. It was thereafter frequently employed as a distinguishing mark for a variety of commercial objects, marketing, and public statements.
