QR code

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!
