Some people tell us not to worry about ubiquitous and promiscuous (meaning always broadcasting/responding to any read) RFID tags. One of the arguments is usually the relative inacessibility of RFID readers, and the fact that they will be priced above levels attractive to anyone but institutions interested in supply chain or other sorts of management uses of RFID.

But RFID is not going to be a one-way technology built on some rigid hierarchy of ubiquitous consumer and individual level tags at the bottom being read by legitimate institutional readers at the top. Its going to be a web of ubiquitous tags in a sea of readers.

Perhaps the clearest wrench in the works of the neat hierarchical model is this plan to include RFID readers into individual cell phones.
