Any RFID, implanted or not, can be shielded with copper, all you need is grounded mesh.

RFID-equipped transit-pass work when it's shielded with copper

An inductive link (notice the coiled wire in the picture) will drop off with 1/d^3 so only close (1cm) communication is possible. Its actually pretty difficult to go beyond 10cm and stay small.

But if you're paranoid, just jam the signal in the vicinity or use copper

2) generate electronic noise during reading. all you need is a simple spark discharge and you won't be able to distinguish anything because it is broad spectrum. marconi used this for a wireless transmitter in the 1890s. (nothing says don't f around like a nice tesla coil imho but thats probably overkill)
