QR codes have suddenly become very popular. Everywhere you go there are many QR codes on the showrooms, streets, sign boards, shops, buses, taxis and even on people’s clothes. In order to know what a QR code is telling you, all you need is a smartphone that is capable of snapping the QR code and translating it into human readable languages. In my experience, most of the QR codes outside are website addresses, but some are contact numbers and other text information. Earlier this month, I saw a QR code poster which took me to a website for a missing dog.
