Smart buckle

Here's one more stretch for an RFID-application,
AirGATE, makers of all things RFID, are prototyping a "smart buckle" child safety seat. The RFID-embedded buckle transmits a radio signal to a reader which triggers an audible warning to the driver if the kid's straps aren't properly buckled. The buckle also makes noise if it has not been disengaged after the car has been parked and the engine has been shut off, "indicating that the child may have been left in the seat." We're thinking if you're a good enough parent to buy your kid this new safety seat, then you're probably good enough not to forget the kid in the car. But maybe that's just wishful thinking.
