AppId is over the quota
They seem to be almost everywhere you look these days, these little blocky features that are appearing on nearly every type of packaging imaginable. They are called Quick Response codes (QR codes for short) and they are a trademarked kind of matrix bar code. They are becoming extremely popular because they are very easy to read and have huge storage capacities when compared to the standard bar code. In fact, QR codes are fast replacing standard bar code technology.
A QR code is made up of dozens of small black modules which are placed in a square pattern that is placed over a white background. QR codes contain information that is encoded into four different modes of data which can be alphanumeric, numeric, byte or binary or something called Kanji.
Developed in 1994 by a subsidiary of Toyota, Denso Wave, QR codes were designed to track vehicles as they were passing through their manufacturing process. It is quickly becoming a highly popular type of two-dimensional bar code because a great deal of information can be stored in them and gathered at very high speeds.
These little powerhouses are quickly taking over in the world of consumer marketing and advertising. In the past they were used primarily in industrial applications but they are being seen more and more in consumer packaging because every smartphone is now equipped with a QR scanner. Savvy shoppers are using them to scan codes to populate grocery shopping lists, look up price comparisons while shopping in stores and download coupons while they shop by the store they happen to be in.
People use them to download movie tickets or URLs for websites they wish to look at. They are clearly changing the way in which consumers relate to products and will significantly alter the way consumers shop for products.
In the Philippines, the National Bureau of Investigation is utilizing QR codes to track security clearances. In smartphones, the technology is being used for a process called mobile tagging which is a process in which data is can be displayed on the screen of a mobile device. Information contained in a mobile tag is usually the URL of the website of the company that has manufactured the brand. Today, most people have an app on their smartphone which allows them to easily scan and read a QR code.
QR codes may also be found on buses, business cards, in magazines. They can be easily added to any object that a person might wish to obtain more information about.
There is no limit to the way in which this technology can be applied. In fact, QR codes are now being used to help people find their lost pets and luggage. A company called Pet Hub is using this technology to help pet owners find their lost pets quickly and efficiently. Information about the animal's vaccine history or even a reward can be included in the code.
Another startup operating in Seattle called Dynotag is marketing QR codes for the rest of us. The company offers a free service that allows users to create a QR code that can be attached to the collar of a pet or even a suitcase. Scanning it will quickly open up information about the owner and the lost pet or item can be reunited with its owner in fairly short order.
