Mobile Tagging

Attending a presentation on mobile tagging. The simplest example is a 2D barcode that encodes a URL, printed as part of an advertisement. Load mobile app, shoot barcode with camera, and URL is loaded in your browser.

Google is extending AdSense and YouTube to support QR Code generation. MS has proprietary tag format.

Can be read from print, screen even plaque.

Privacy issues. Is URL malicious? Perhaps creator of reader (eg google) could provide clearinghouse that qualified URL before redirecting to it.
