QR, short for Quick Response, technology was originally developed around the same time as the earlier smart phone models. In those days, you used to have to download a QR code reader app in order to scan the barcode and open the intended page. Nowadays with the newer technology, it all happens using the camera app which comes installed on everyones phone, simplifying the entire process and making it accessible to a wider audience.
