What is a QR Code?
“QR” stands for Quick Response and the “Code” describes the ability to take most any kind of information or date and translate it into something that can be electronically read. QR Codes operate very similarly to traditional barcodes in that they are tied to a particular product or item. However, where barcodes are usually limited to about 20 digits, QR Codes can handle thousands.
Originally, QR Codes were used in the automotive industry to track vehicles and their individual parts, they are becoming more and more popular commercially to provide quick access to all types of personal and marketing communication that people with smart phones can use to read them and access their information.
QR Codes vs. Barcodes
As mentioned, barcodes have a very limited capacity to store large amounts of information. Basically, the way a barcode works is a barcode reader measures horizontally the number and width of a series of vertical lines. The unique configuration of vertical lines is then associated with a code of up to 20 digits that represent a product number and/or price.
Conversely, QR Codes use readers that identify a pattern of tiny black squares and the white spaces in between them, both vertically and horizontally. QR Codes will vary in size – both in the printed area they occupy as well as the number and density of the black squares they contain – which allows them to store exponentially larger amounts of information. With this increased ability to store information, QR Codes can not only identify small product codes, they can convey entire marketing messages and detailed contact information.
How are QR Codes read?
The first step in using a QR Code is to generate one, and there are several QR Code generators available on the internet. The one I used to generate these QR Codes was by ZXing and can be found atwww.zxing.appspot.com/generator. The first thing you’ll do is choose what kind of information you want your QR Code to contain. Once you select your code option and fill in your details, click submit and your code will automatically be generated for you.
Once you have the code generated, you can copy and paste the embedded URL into your website, blog or other electronic medium, or you can save the QR Code as an image that you can use on any of your printed materials.
Now that you have your QR Codes in place, you need a reader that will scan them. Many of today’s smart phones come with an application that will read barcodes and QR Codes. If you do not have a Scan app, simply do an app search on your smart phone and several will be available.
When you open your scan app, it will look like a camera that is ready to take a picture. With most scan apps, all you have to do is position the viewer over the QR Code, let it focus on it for a second and it will automatically retrieve and display the code’s information or take you directly to the website that it is associated with.
Next week, I will list several ideas and ways that you can use QR Codes to promote yourself, your business, your event or whatever you want to communicate. In the meantime….
