You may have seen these recently in a variety of places, you may already know people speaking about them within the realm of mobile and wondered precisely what the heck they are. Quick response codes (described as “QR” codes) are a very convenient way to display a small bit of information that is effortlessly scanned and processed typically by mobile phones allowing physical items to almost become interactive, by providing information that is effortlessly scanned like a site URL.
To make a simpler analogy, lots of people are aware of Universal Product codes (called UPC codes). Everything you buy at the grocery store (and almost any store right now) has one of those that the cashier will scan. The computer then immediately knows precisely what the product is in line with the code which it picked up.
Does anyone remember the days of grocery shopping and also the cashier had to punch within the prices and codes for just about every item you purchased. They had to memorize these types of within their head and whenever they forgot? They had to pick up the loud smart phone, make an announcement within the store asking for somebody in that department to enable them to out.
Think of qr code service codes as UPC codes but instead they are used in a much broader spectrum, not simply 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 are at a trade show and you are walking by my booth. You want to find out more information about my company, so you get into your smart phone and start fumbling away trying to type in some long URL (which is on my display) into your browser, and off you go.
The other option could be for me to display a QR code (on my display), you take your phone and scan it the same as cashiers scan items at the supermarket, and 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 can place these little codes anywhere. People with free scanners on their phones (iPhones, BlackBerrys, Androids, Nokia, etc.) can quickly scan the code and find out additional information, like opening up a web page.
Whole Foods Market (popular in the US/Canada) uses these within their stores. I was recently sitting down to have a bite to eat at the one in Yorkville Toronto, as well as on the table where I was sitting was a table tent with two Quick Response codes. It was obvious where they will take me if I scanned them, one would take me to their Twitter account, and the other would take me to their Facebook page.
If I was serious about checking out their Twitter or Facebook page, rather than opening up each respective app and going to the search function and typing within their name etc. (I likely would not, too much effort) I could pick up my smartphone, scan the QR code and automatically open each page!
