Kidnappings in Mexico have worsened in the last five years, sky-rocketing by 371 per cent. So too have the demand for those RFID implants that were said to allow authorities find the victims. Except for one thing: they don't work.
The main problem is that the technology, for a number of reasons, couldn't have worked in the first place. For one, the implants are much too small for a satellite to pick up. And that's without taking into account the barriers the implant's signal would have to overcome — that is, metal, concrete, and the water of the human body. For another, the implants can't be trusted to broadcast a signal without losing its teeny tiny charge.
And even if the police did manage to pick up the signal, there'd be no time to mount a raid to save you. All told, you're probably only about 1 per cent less screwed.
Xega charges people seeking the implant $US2,000 up front, with annual fees of $US2,000. For their money, implant customers get a radio frequency identification chip implanted into the fatty tissue of the arm.
