This is especially true of 3rd generation handsets which have cells much closer together and handsets with built in GPS. The phone companies talk about using this to produce targetted content based on the users location. RFID tags are also being trialled by clothing retailers actually embedded into the clothing rather than just on labels in the store, so they can control stock movement and prevent theft, but are the tags disabled properly on purchase? Admittedly no one has to have a cellphone, but this is a heads up about what else can happen.</blockquote>
