A sign in San Francisco, starting Monday, identifies approaching Mini Cooper drivers by using a signal from a radio chip embedded in their key fobs.
The boards, which usually carry typical advertising, are programmed to identify approaching Mini drivers through a coded signal from a radio chip embedded in their key fob.
The messages are personal, based on questionnaires that owners filled out: “Mary, moving at the speed of justice,” if Mary is a lawyer, or “Mike, the special of the day is speed,” if Mike is a chef.
RFID (radio frequency identification) technology is making the experiment possible. Researchers and entrepreneurs have labored for decades to extend the practical uses of wireless tracking using radio tags.
Cool.
That's Right,
