A Smartwatch that remembers too well

So there's a big problem with building an RFID-enabled smartwatch that could help you keep track of all your stuff and make sure you never leave home without your keys ever: it leads to some serious privacy issues, since anyone with an RFID scanner could probably keep track of your stuff as just as easily as would. To get around this, researchers at the University of Washington are working on ways that RFID tagged items could only seen by the smartwatch itself, and trying to combine an RFID reader into a smartwatch at a feasible price, since current readers are roughly $1000.
