What is a QR code?
QR code is short for Quick Response Code - meaning that it can be read quickly by a cell phone. They are used to take a piece of information from a transitory media and put it in to your cell phone.
They’re everywhere, from websites to advertisements and look a bit like barcodes but, instead of vertical stripes, they are made up of square–shaped patterns. As an increasing number of businesses start to use them, they are becoming more and more recognizable and many smartphones now come with built-in QR readers.
While they may look simple, QR codes are capable of storing lots of data. But no matter how much they contain, when scanned, the QR code should allow the user to access information instantly – hence why it’s called a Quick Response code.
