You may have seen these recently in several places, you may have heard people talking about them in the realm of mobile and wondered exactly what the heck they are. Quick response codes (called “QR” codes) are a very convenient way to display a small bit of information that is quickly scanned and processed typically by smart phones allowing physical items to almost become interactive, by providing information which is quickly scanned like a website URL.
To make a simpler analogy, most of the people are familiar with Universal Product codes (known as UPC codes). Everything you buy at the food store (and almost any store right now) has one of those that the cashier will scan. The computer then immediately knows just what the product is in accordance with the code which it picked up.
Does anyone remember the days of grocery shopping as well as the cashier had to punch in the prices and codes for every single item you purchased. They had to memorize these types of in their head and whenever they forgot? They had to pick up the loud mobile phone, make an announcement within the store asking for someone in that department to enable them to out.
Think of QR codes as UPC codes but rather they are employed in a lot broader spectrum, not just to ‘identify’ products but to convey ‘information’ of some kind.
The most basic (and popular use) of Quick Response codes is to display website information (a site address). Lets say you’re at a trade show and you are walking by my booth. You want to find out additional information about my company, so you open up your smartphone and start fumbling away trying to type in some long URL (that’s on my display) into your browser, and off you go.
The other option will be for me to display a QR code (on my display), you take your mobile device and scan it just like cashiers scan items at the super market, and also your smart phone automatically starts loading my website, how is that for convenience?
What about billboards outside on the street, or bus shelters while waiting for public transportation. You may place these little codes anywhere. People who free scanners on their own mobile phones (iPhones, BlackBerrys, Androids, Nokia, etc.) can quickly scan the code and find out more details, like opening up a web page.
Whole Foods Market (popular in the US/Canada) uses these in their stores. I was recently sitting down to possess a bite to eat at the one in Yorkville Toronto, and also on the table where I was sitting was a table tent with two Quick Response codes. It was obvious where they can take me if I scanned them, one would take me to their Twitter account, and also the other would take me to their Facebook page.
If I was interested in checking out their Twitter or Facebook page, rather than opening up each respective app and going to the search function and typing in their name etc. (I likely wouldn’t, too much effort) I could pick up my smartphone, scan the QR code and automatically open each page!
