The notion of assigning every piece of paper that passes through a printer a unique ID encoded either on the surface or in the substrate of the page, regardless of its intended use or perceived importance, could prove to be a breakthrough of magnitude comparable to the now ubiquitous concept of referencing a webpage through the use of its Universal Resource Locater (URL). We see many opportunities for using chipless ID in the world of everyday documents, but also many challenges. In this paper, we begin to explore the ways this new technology can be used to enable advanced document management functions, along with its implications for the ways in which people use documents.
