QR Tagging Explained
QR (Quick Response) Codes are special 2D barcodes that you can tag with your mobile phone.
Tag a QR code to do comparison shopping, find the best deals, get more info from a youtube video, store contact info, or even get navigation and driving directions.
The trick is in the mobile app - it uses your phone's camera to read hidden content in the barcode, and off you go.
So grab your free app and tag a QR code!
