Reading - or scanning - a QR Code is an easy 3-step process, as explained in the graphics below. You have to open your reading application and point your camera at the QR Code. It is then recognized by the application which carries out the associated action - like opening a web page.
QR Codes are read by so-called "reading applications", which are basically barcode scanners. There are dozens of them that you can download on your smartphone through your stores. But be careful, these readers are not all efficient at reading QR Codes! That is why we recommend the i-nigma reader for better performance.
