What's wrong with this picture???
1. You can't receive calls. Only make outgoing, from a location which is known to fascists.
Let's try again. TEMPEST sheilding and outgoing calls are not compatible.
Of course outgoing is impossible inside the TEMPEST box. But you don't reveal the intermediate locations you drove through to get to where you broadcast. I drove to Cheech's with my phone unpowered and my toll-road-transponder boxed. Then I drove to the library and unboxed my gizmos. Simple. The gap must have been a "glitch" to the semiclued Big Bro.
2. Use it for your toll-road-transponder too.
And you own one, why?
I don't, because I'm a cheapo and professional paranoid. But in my 'hood, there are many tollroad which use them. Otherwise you have to stop and toss coins. Of course your license and face are video'd anyway. If I had one, I would box it unless I was driving on a toll road.
Just for the record, after writing that last missive, which reflects an experience almost 25 years old, I did some quick googling on current body armor. My experience *probably* does not hold with the latest (post 1999) fiber systems. But I still wouldn't bet my life on it. -- Yours, J.A.

For this purpose, plain power-off should be enough. The "RF fingerprinting" I mentioned earlier is a different grade of threat though; against that, shielding is necessary.

There are two kinds of tags, active and passive. Active ones have their own power supply on board and transmit on their own, passive ones need external field to feed them with power. A good thing could be a detector of the passive tag readers; similar to car radar detectors, just on different frequencies. A detector of active tag readers should be possible to design as well; the receivers are usually designed on the superheterodyne principle, and the leaks of their oscillators can be detected from distance. In some countries/states police uses detectors of radar detectors working on this principle, and there is also some project of advertisement corps to receive the leaks from the car radios and figure out the major demography of the population using a given road and set the "most suitable" face of the billboards on that road for that particular target group. So the technology is already out there, just has to be opensourced for public benefit. Shame on my lack of RF skills necessary to do this :(((
