Can their receiver coils be overloaded?
Those things get added to all sorts of non-obvious things,
and start to interfere with our privacy .

try a high power RF source like a microwave oven, or an EMP.

high(ish) temperatures may work too, I've seen some tags
fail at as little as 100C,but these were ISO15693 tags (VHF)
but I expect you are more interested in ISO18000 tags (UHF)
which use dipoles instead of coils, but should still be
succeptable to sufficient power.
