Reading QR Code Using Raspberry Pi Camera

Introduction

A QR code (Quick Response code) is a type of matrix barcode. It is a machine-readable optical label that contains information about the item to which it is attached. The QR system became popular due to its fast readability and greater storage capacity compared to standard UPC barcodes. In this tutorial, I will share on how to use the Raspberry Pi camera as a scanner and a reader of QR code.
