QR-Codes-In-A-Nutshell: Basically, QR (Quick Response) codes are super-barcodes. Once created, a QR code encodes information in a 2-dimensional space, meaning on the page of a pamphlet, in an email, or on an advertisement on TV. Often used for commercial purposes, our library uses them for expanding our services.
How are QR codes different from barcodes? It is all how the information is encoded. QR codes are much more advanced than traditional barcodes. Barcodes only consist of vertical lines; whereas, QR codes encode data both horizontally and vertically just as if it were in a chart, or grid. QR codes can encode a lot more information than a traditional barcode. We’re using QR codes so that when the QR codes are scanned with the proper software, an interactive response is triggered, and a website is launched or a file is downloaded at the snap of a scan.
Here are a couple places you may have seen QR codes:
What software do you need to read the QR Codes placed throughout the PCL? All you need to have is a SmartPhone or iPad. For example, there are a few apps available for the iPhone that can read QR codes, including the free RedLaser (Barcode Scanner and QR Code Reader). Most new Android phones, Blackberries, and Nokia handsets have the capabilities to read QR codes right out of the box. If you are a Windows Mobile user, you can download QuickMark.
How does it work? All you need to do is to launch the appropriate application on your phone, point your phone’s camera at the QR code you want to scan, and start exploring.
