What is a QR Code and how do they work?

QR means "quick response" and QR Codes allow users quick and easy access to web pages, PDF files, videos, forms or other information.

A QR Code is an extended version of a barcode and can contain any text up to 4096 characters long.

QR Codes are created using a QR Code generator that encodes the information for a QR Code reader. The QR Codes can then be read with almost any smartphone that has an integrated camera.

Recently, QR Codes have been used effectively to provide quick and easy check-in at restaurants, cafes, hotels, etc. during the global Covid-19 pandemic.
