[WebPub] QR Bar Codes

[Lisa C Mayer]

I just learned about this.  You download the QR app on your smartphone, and use it to snap a photo of a QR bar code.  The scan will open up the website the bar code refers to.

You can even make a stamp for phone numbers, map locations, and more....hospitals are using it too for patient id's, medications, etc.


"QR Codes storing addresses and URLs<http://en.wikipedia.org/wiki/Uniform_Resource_Locator> may appear in magazines, on signs, buses, business cards, or just about any object that users might need information about. Users with a camera phone<http://en.wikipedia.org/wiki/Camera_phone> equipped with the correct reader app<http://en.wikipedia.org/wiki/Software#Application_software> can scan the image of the QR Code causing the phone's browser to launch and redirect to the programmed URL. This act of linking from physical world objects is known as a hardlink<http://en.wikipedia.org/wiki/Hardlink_%28homonymy%29> or physical world hyperlinks<http://en.wikipedia.org/wiki/Physical_world_hyperlinks>. Google's mobile Android operating system<http://en.wikipedia.org/wiki/Google_android> supports the use of QR codes by natively including the barcode scanner (ZXing) on some models and the browser supports URI<http://en.wikipedia.org/wiki/Uniform_Resource_Identifier> redirection, which allows QR Codes to send metadata<http://en.wikipedia.org/wiki/Metadata> to existing applications on the device. Nokia's Symbian<http://en.wikipedia.org/wiki/Symbian> operating system is also provided with a barcode scanner, which is able to read QR Codes.[citation needed<http://en.wikipedia.org/wiki/Wikipedia:Citation_needed>]

Users can also generate and print their own QR Code for others to scan and use by visiting one of several free QR Code generating sites."
