Dec 2011 -- QR Codes Explained
QR Codes are those funny little black and white blocks that are showing up everywhere -- store windows, printed material, advertising and web pages. There's an example on the right here.
If you have a smartphone or iphone, tablet or ipad, or a web cam on your device, you can use any free barcode reader to read these QRCodes.
Any kind of information can be embedded into a QRCode, contact information, street address, telephone number, txt or sms number, eMail address, website URL, or just free text. The Barcode reader will interpret the QRCode and ask you what you'd like to do with the result.
The QRCode to the right has Indigo Computer's mailing address, phone number and eMail address. Read it with the barcode software, and you can store it in your address book for future reference.
Even niftier, there are a bunch of online QRCode generators you can visit to create your own QRCode blocks. Here's one at barcodeinc.com: http://www.barcodesinc.com/generator/qr/. Learn more about QRCode formats at Google's page here: google.com/p/zxing/wiki/BarcodeContents
