Utah Firm Wants to Go Where GPS Doesn't

Thinly veiled RFID wrapped in PR spin.

The problem isnt the ability to create a small and cheap transponder chip - the challenge is the actual *reader* infrastructure.

Even in this case - the S5 chip still relies on the reader infrastructure being built out.

For ages people have been concerned with RFID / RTLS tracking invading their privacy - but it was a ways out due to the fact that any reliable tracking system needs to have ubiquitous reader coverage.

GPS is the answer to this - but cost is the issue. There is no difference in the problem being addressed here - except they have (possibly) a novel approach through ULF on 900 mhz.

In our rush to track everything anywhere, no one seems the least concerned over the health implications of the effects of RF transmission in close proximity to our bodies. It can be argued that it is a minuscule amount of power driving these devices, but the cumulative neurological effects of cell phones, GPS, wi-fi, etc., are unknown.
