It is a bit off, you're right.
The difference between the Beeb's version and what it is, is that this is NFC, and it's powered by the interrogator.
That's why it isn't CT worthy, nor are the other implants. The reason is, neither this nor the Verichip or any of its descendants actually transmits
anything at all. They don't even have any sort of power.
NFC parts get all their power from the interrogator device. This emits a time-varying magnetic field to the part, the part has a coil in with a
ferrite in it (that's the coil they mention in the photo), and that picks up the interrogator's field. The implant converts that to a bit of power,
and runs the test. When it's done, it signals back to the interrogator by throwing a load onto and off of the coil, sort of like signaling to someone
pushing your car by tapping the brakes. The implant doesn't transmit anything, it just changes its loading.
When you take off the interrogator, no power, the thing is off.
You use magnetic fields because being made out of wet salty meat, you're not very conducive to radio signals going through. Straight h-fields don't
care, so that's why you use magnetic coupling in implants. See the verichip photos? That coppery looking thing at one end is the coil.
However, magnetic coupling has a couple of insurmountable bits that don't really affect their use in legit medical devices, but make them a CTers wet
blanky: the power density of an h-field coupling falls as the sixth power of the distance. So while it's a cinch to drive one a few cm away, get a
meter away and you're using hundreds of times the power. And then there's a physical barrier to it, even if you had the world's most perfect setup
and the Niagara Dam to power it, you hit what's known as the 'lambda wall' about 13 meters out, and no one's going to read the data beyond that,
because it's near field. Outside the near field for that frequency, no data.
