QR Codes storing addresses and URLs 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 equipped with the correct reader application can scan the image of the QR Code to display text, contact information, connect to a wireless network, or open webpage in the phone's browser.
The QRCodeGenerator content source plug-in creates QR barcodes from a string read from a variable and produces an image in your file system that’s inserted into the Pageflex template.
