Worth of QR codes
The advertising and marketing gurus should take note of this. I have noticed QR codes from supermarket grocery items to articles in the Harvard Business Review. It seems more and more information is being pictorially represented using -if I may borrow your words – those “black and white squares”. That simple phrase shows the beauty of these – holding massive information yet so tiny and fragile in its truest sense. I bet the phenomena would pick up in Pakistan – it’s just that no body has noticed them yet here for some reason. The age old maxim that a picture is worth a thousands words has just been redefined.
