In an age, the information age that is, where we want everything in an instant, the QR code is a convenient way to get the information you want in a flash.
QR is short for Quick Response.
The funny looking black and white square that looks like a corn maze gone bad was developed by a Japanese car maker.
It enabled the car maker the ability to code pieces of information about a vehicle as it moved down the assembly line.
Each station would read the QR code and know everything necessary to proceed with the manufacturing of the vehicle.
Unlike traditional bar codes which only have one piece or one line of information, the QR code can hold several pieces of alphanumeric information.
Invented in 1994 by Denso Wave a Subsidiary of Toyota, the QR code is now widely used in many applications the least of which is in advertising.
While Denso Wave still holds the patent on the technology behind the quick response code, they have granted free license allowing anyone to use it and the usage is growing at a rapid pace.
The traditional bar code which is nothing more than a series of specifically spaced lines which only code one line of information, usually a series of numbers are mechanically scanned by physically bouncing a narrow beam of light onto the bar code area.
What's really happening is the narrow beam looks at the white space between the series of lines and depending on the size of the white or void area reflexed back from the white space will determine what is decoded.
Quick response codes on the other hand, read by an optical reader such as what is in a camera.
Most cell phones already have cameras on them to take pictures and movies so the only thing missing is the software to decipher the code once it is read by the camera.
Because of this technology many pieces of information can be encoded into a QR code.
While a traditional digital camera will work simply because it is taking a picture of the QR code it does not have any programming that allows it to decipher the code unlike smart phones which has an array of apps that can be used to decipher these QR codes for you.
In future articles I will discuss the possibilities of how you can utilize this technology in your business.
We will also talk about how to read a QR code, how these special codes can be used in various applications.
This is a fast growing phenomenon which has great potential to will help get your information out there and get people connected to you quickly with a simple snap of the camera.
