JFC. There are always a few "fringe" elements, but if this is a widely accepted belief then I am even more concerned for our society (if that was possible).
Let's clear something up right now. For starters, cutting edge EUV Lithography can image structures on the order of 5nm (about 25 silicon atoms across)... and maybe 3nm. Freaking tiny to be sure. But even that small there's just not enough real estate inside a hypodermic needle to create a MEMS device with enough complexity and meaningful functionality (at least in the sense that conspiracy theorists imagine). But for the sake of argument, assuming that was possible, you'd still need some incredible battery or chemical reaction tech to power the damn thing .... And even if that was possible, the wireless signal strength would be measured in nano or pico watts! Great "tracking" tech that has a range likely measured in centimeters. THIS IS PURE FUCKING NONSENSE!
A bit of a correction. When I wrote the above rant, I was pissed about having to beg out of a family function due to a couple of anti-vax boneheads. In my haste it seems that I forgot about RFID technology - which has been successfully miniaturized to sizes that could be injected with a typical vaccine hypodermic.
THAT SAID, these are purely ID devices with zero processing capability. So the idea of "software" updates is complete bullshit. Also, the "tracking" range for these microscopic devices is measured in millimeters! But perhaps the biggest irony of all is this sub-culture of anti-science thinking is being spread on social media - largely using cell-phones and other mobile devices which are themselves the ultimate tracking devices of all time.
So, even though I incorrectly jumped to conclusions about the tech aspects, I stand by my previous statement that using the vaccine for tracking or "mind control" (ROFL) is PURE FUCKING BULLSHIT!
MiniaturizationRFID tags are easy to conceal or incorporate in other items. For example, in 2009 researchers at Bristol University successfully glued RFID micro-transponders to live ants in order to study their behavior. This trend towards increasingly miniaturized RFIDs is likely to continue as technology advances.
Hitachi holds the record for the smallest RFID chip, at 0.05 mm × 0.05 mm. This is 1/64th the size of the previous record holder, the mu-chip. Manufacture is enabled by using the silicon-on-insulator (SOI) process. These dust-sized chips can store 38-digit numbers using 128-bit Read Only Memory (ROM). A major challenge is the attachment of antennas, thus limiting read range to only millimeters.
