The QR code at a glance
This specific technological application allows us, with just a simple rollover of your mobile phone camera over the QR Code, that is either printed or in the screen of your computer, to access WebPages, images, videos, texts etc.
QR Codes are 21st century’s barcodes: they provide us with encoded information without the necessity of a specific type of appliance
They are legible from all devices that have a camera and connect to the internet.
The encoded information can either be stable or dynamically change as any other webpage.
In reality, QR Codes are the same as barcodes, but they are recognizable by any device that integrates a camera and an internet connection. QR Code analysis results to a text that can be up to 4 thousand characters long, accompanied by photos and videos.
Imagine that you read a text that your professor gave you and you want to access a webpage- source or a video that it mentions, from your cell phone, your tablet or your pc. What you would have to do would be to type the address. Now, you only have to open the cover of your phone camera and “bring” it on the QR image, needless taking a photo. Your phone “understands” the
existence of the QR Code and asks you if you want to visit the website!
