In store windows and on counter tops and on displayed products, there’d be a placard with the header: Add to iPhone Safari Bookmarks. Below the header is a barcode type of graphic with four distinct marked corners.

Line up the camera on your iPhone so that the graphic fills the screen and take a shot. The phone recognizes the image as a target and takes the information from the barcode to add a new bookmark to Safari, taking you to the website of the placard the next time you tap it.

The Apple website has a page in the iPhone section where anyone can enter a title and a URL for a new placard to be produced online; then they can simply print it out.

Magazines could include the placard in ads (if the camera is good enough to focus that close.)
