That's not true according to what I've ready.

The IEEE and some other entities have done experiemnts and stated that
the distance various forms of embedded ID can be read is far greater
than anticipated.

Besides, even inches is too much when done by the wrong people.

I pass within inches or feet of things which could ID me all the time in
stores, malls, and public buildings.

No thanks.
