RFID ain’t rocket science. All it is at its heart is using EM radiative power to induce energy into a system, and then the system turns around and gives a coded reply.
That it happens with very low voltages isn’t such a big thing, it’s that things are being put together in volume, repeatability, and with supporting infrastructures. All of those put together make it the powerful solution or scary situation that RFID is.

Exactly right. Rather than getting all in a lather over RFID and going nuts with conspiracy theories, do some reading or find a tech-savvy engineer or internet group and you’ll quickly see this technology is about as sinister as a USB drive.
