    This QR code stores the URL of the DDI Alliance website, www.ddialliance.org. A QR (Quick Response) code is a type of barcode that can be scanned and deciphered by many mobile phones. When a mobile phone that is equipped with a camera and QR code reading application scans the code, the device will open a web browser and display the DDI Alliance home page. The DDI Alliance QR code is provided as a high resolution JPEG file so that it can be easily integrated into any type of printed materials from brochures to posters.
