You’d almost have to be living in seclusion not to notice seeing more and more QR codes. They are showing up on direct mail pieces, business cards, display ads, in-store displays, on buses, and all sorts of other media, even electronic media.
But what the heck is a QR code?
QR is short for Quick Response, with that being the intention from the inventor, to be able to decode information at high speed. The codes themselves, similar to bar codes, are readable by smart phones, i.e. iPhones, Droids, Blackberrys, etc., or those phones that are camera enabled and have a QR code reader application. Some phones come equipped with QR code readers while others will to have one of many available free apps downloaded to it. Here is a site that lists several code reader suppliers, http://www.mobile-barcodes.com/qr-code-software/
The difference between a bar code and a QR code is in that a QR code can hold much more information than a bar code.
Initially, QR codes were used in Japan and South Korea, and have been in existence for almost two decades, to keep track of vehicle parts in the manufacturing process. Their use has spread over a much broader spectrum, including where they are becoming more prevalent these days, marketing businesses.
A QR code will give a consumer immediate access to information relevant to them. Expect to see more and more of these as this great marketing tool catches on in the US.
A QR Code looks like the image below and has other visual variations based on the amount of information encoded in them. Encoded information can be text, a web address, contact information, special offers or other data.
