More on RFID in fiction

RFID is becoming the deus -ex machina of choice for many TV shows - Hawaii 5-0 had  a storyline where the baddies were triathletes, and our heros were tracking them via the championchip device  complete with bleeping point on electronic map. However the dastards had swapped them and so there was more running etc. until good triumphed. Whether this increases or decreases RFID acceptability remains to be seen

Big Bang Theory

On the TV last night 21st October ( episode not yet on TVNZ Website )
Sheldon was busy tagging his socks with RFID so he could select the correct ones for different situations. Very similar to the "magic" bag http://www.hinz.org.nz/uploads/file/2008conference/P08.pdf . One thing I wondered was why he didn't use that technology to ensure that he didn't forget his USB stick ?
