The explainer part of RFID is very good, and part of the worries are justified, but some arguments fall apart. because physics!
As explained, an RFID tag biggest part is the antenna. and it needs to be a very specific size because of the mentioned frequency resonation/response effect.
Again, as explained, the RFID transmitter portion sends a signal that both powers and detects a response from the tag. That's how the entire system works.
The problem with the idea that you could make a clandestine RFID system that can be detected extremely long distances is twofold:
1. If you want to send signal long distance using lower frequencies, you need larger and larger antennas. For this, you can think about radio antennas, TV antennas, or something like the difference between 4G and 5G antennas. Higher frequencies also have a harder time going through dense objects - this is why millimiter range 5G has to be short distance line of sight;
2. If instead you wanna send it further away by upping the amplitude of the signal, that is power, than it also becomes a problem of either coil size, active device with battery to fit, or a combination of both. A passive device can't generate enough power, particularly if it's small, to transmit back a signal long distance.
It's in the explainer itself: the passive RFID tag needs to be powered by the scanning signal and transmit back a response. It's powered by the signal because the antenna acts both as a transmit/receive antenna, and as a coil to induct power.
Now, you have to think about wireless power tech. Qi Chargers. The entire reason why we still don't have long range high output wireless power systems is because of physics. in order to transmit power wirelessly using coils, enough to charge a smartphone which is usually around tens of Watts, you need relatively big coils that are milimeters from each other. Fast wireless charging that are the latest in evolution are using multiple coils to reach fast charging standards.
Worse, the more power involved in a wireless power system, the more loss through heat you end up with. This is why fast wireless charger bases usually have a fan or some form of heat dissipation.
That is all to say that RFID tags are only possible because the passive tags require a teeny tiny ammount of power just enough to operate for miliseconds, send back a very weak signal, juuuust enough for it to reach the reader. It's a system that was carefully designed to hit the physical limits.
If you need a tag to send back data long distance, it'll either need more power with either a big coil or by being active with a battery, or it needs to have a big antenna, or a combination of both. Making it then, way harder to conceal.
But, the concern on just regular sized RFIDs is justified. You can have an array of detectors/listeners spread in a wide area that could collect data that way.
Only it's also worth noting that it'll need to be tied to some mass surveillance database somehow, because you really can't hold a lot of data in a chip as small as an RFID chip.
Which then leads to. it not being very feasible because we already have several other methods of collecting data and surreptitiously tagging people anyways. For instance, tracking people inside a store for commercial purposes? It's been done several times already using Bluetooth and Wi-fi from smartphones - including non consensually. You don't really need RFID dust to track people. most people already have beacon devices with them at all times. Instead of spreading RFID dust around, a honeypot for Wi-fi and/or Bluetooth should be enough for most situations.
Now, if you need to tag an individual through some method that isn't reliant on a smartphone and other electronic devices. well, perhaps it'd be interesting to track RFID tags. but it's kind of a convoluted way of doing it, and there should be plenty other cheaper and easier alternatives. Special types of paints and chemicals, active trackers, biosignatures, etc.
I was just reading about our external microbiome the other day. did you know we all basically have a microbiome floating around us at all times, one which is as unique to us as our gut flora? Yep. It's how dogs can track people by -scent-. it's not just smell as in how we conceptualize it, it's actually an entire microbiome floating around us that is rather unique to each individual. And yes, overtime it could be used as unique identifier.
So, there you go. Hope I didn't leave even more people in despair. xD

Po, the Pope says to get the vaccine. Do you stand against the Pope? Is he deceived, or deceiving others? Po, why be so anti science about Covid? Why? - You can't adapt to a new thing? Freedom freedom! YES, but OTHERS DESERVE FREEDOM FROM YOUR GERMS! YOUR WORDS, ENCOURAGE SPREADING OF COVID TO KILL OTHERS! That old person near you in a store or public place. You PLAY GOD with THEIR life! You believe you should play Russian Roulette with THEIR LIVES? PROTECT that old mother, that old father! Or young child with asthma! Your words encourage the anti vax, anti mask mob of the LESS scientific. Or you Asymptomatic SPREAD it and it goes home with someone who KILLS A CHILD! At least be NEUTRAL and QUIET COMPLETELY. Or STAND WITH SCIENCE! How many have DIED because of YOUR WORDS!
- Should surgeons operate on YOU without wearing a mask? No! So the mask is useful as scientific method.
- You wear underwear. To protect others from fecal germs on public chairs. You can't wear a mask to protect others from other germs?
- You wear seat belts? They KILL some people! But you know they are generally life savers!
- I keep a life vest nearby when I'm out in the ocean. I've never needed it, but I WANT it for some RARE time!
- You wear shoes in restaurants? Or shout Freedom Freedom to that law? Shoes keep my feet germs off your feet, and yours off mine!
- TB, Tuberculosis! 100 years ago laws were passed to stop public SPITTING. TB is spread when the spital dries and becomes dust in the air. FREEDOM! Spit spit so you have freedom! OTHERS deserve freedom from TB!
- You use passwords? They are a pain, cost time and effort! But they are RARELY needed to keep out the badies.
- You DO KNOW measles vaccines have SAVED MILLIONS of children! Since 1800s, worldwide, 100s of MILLIONS have been SAVED by vaccines. And YES some DIED! But we all KNOW this but are happy for the science.
- Pandemics HAPPEN. Why focus on 5 doctors worldwide who are AGAINST the current scientific consensus on Covid? And avoid the MILLIONS of doctors and scientists that make all science back the consensus view! IS EVERYONE LYING AND DECEIVING BUT THE RARE FEW YOU AGREE WITH? THOUSANDS of Doctors lying and rare voice is correct?
- Science! Science MEASURES. Gathers accurate NUMBERS. The NUMBERS do not support your thinking about covid. It is NOT -just the flu. - The entire world's doctors and pandemic focused scientists are NOT WRONG and You and some anti-science people correct!
- Do you avoid electrical shock when working? Yes! Why not avoid germs during a pandemic?
- YES! Some, many are asymptomatic! GREAT! But they still SPREAD IT to those who DIE. Some old grandmother. Some sick person. Someone not as healthy as you. A child with Asthma! You really want to KILL some random child or children with your actions or attitudes or words! All because YOU aren't young enough in thinking to adapt to a new thing. OTHERS, not you. Think of OTHERS. Freedom for OTHERS, not only you!
WEAR underwear! Wear shoes. Wear a seat belt. Wear a mask in a pandemic. Wear the shield of vaccine protection. A young maid taught doctors the vaccine idea. The poor had discovered a trick to avoid dying as often. Vaccines use that idea since 1800s. It HELPS po! SCIENCE is imperfect but better than the alternative po!

I'm not concerned about rfid in these snake oil vaccines.
Youve stated thats not likely based on the size of the rfid unit. There's a little bit more to this story.
The vaccine nano particles, as shown in the Japan studies, pre covid emergency use being enacted, do not sit locally at the site of injection as was the claim at time of submission. For what ever reason the Japan study was omitted during the submission.
Perhaps if people knew that within 4 Hours the nano particles reach peak saturation in area's not at the injection site.
These area's of saturation include the Ovaries and Bone marrow. With suggestions being that it also affects the glands so lymphatic system, further research reports pending confirming this.
So now you have nano particles in not only 1 wait 2 but now a 3rd with no doubt another variant or other threat to come.
So is there a possibility that using static electricity it would be enough to power such a device. that is low power and only needs to report to a phone or smart device.
The sum of the parts vax after vax being enough to gather in certain locations in the body to form a solid enough source to bounce back a ping to it from a local smart device or even wifi.
Or on another not if a nano bot at some later time arranges these nano particles into another structure.
Yes its all theory and crazy talk.
Try telling people of the 1890's what would be happening now.
Theyed reply - its Crazy talk and never happen their government would stop it. instead of instigate it.
. riiight.

The type of tag you showed, built into a card, operates at very low frequency, around 125 kHz. The maximum range of these tags is about 50mm. I know of no scenario where these can be read from a distance, even several inches, no matter what the transmitter does. If you attempted to trigger one of these with a high power beam, the tag is still only capable of transmitting a miniscule amount of power, which would quickly diminish to nothing just a short few inches from the tag. There is no conceivable situation where these tags could be read from hundreds of miles away. Anyway, they have a capacity of only a few bytes or tens of bytes, so the amount of information is pretty minimal.

Thank you sir!
You are correct that most of the population is oblivious to this technology or simply doesn-t care.
As you said I know New York licenses are RFID equipped (I do believe even the non enhanced ones)
I have always been concerned about how easily one could be tracked simply by walking through a doorway or store entrance, personal data being mined only to ultimately be sold for marketing purposes.
That said please make a video about what those cautious can do to protect their information.
do those RFID blocking sleeves really work?
Btw
I think there is even RFID technology in paper money, correct?

During the Second World War there were signs everywhere telling people, watch what you say, someone could be listening. Little did they know their children and children and their children-s children would live in a world where nowhere in your home or outside would be safe from prying eyes and big ears. Kids today really don-t realize that when they post videos on YouTube and TikTok it will be there waiting to expose what they did, even if your a proper grandmother now, those videos of you skinny dipping or extremely intoxicated will be there. What will your children and grandchildren think? My my my lol.

i enjoy taking the rfid tags from items that were not deactivated and placing them in my shoe or wallet. then the alarm goes off every time i walk through the doors of certain chain stores. if their security camera shows me entering a store and alarm going off, then if they try to search me when i exit the store they are going to have a large lawsuit! the purpose of using the tag to set off their alarms is to make them shut down the unit. as for my debit cards etc. i use a stainless steel money clip to block then from being read without my permission

Not just in theory, this technology has already been used for listening devices in the 50's, when the Russians used one to spy on the US embassy in Moscow. It was a passive device without a power source, which they were powering from a distance from outside the embassy, so it was impossible to detect when not in use. I think I now finally understand exactly what they did and how they did it, after seeing your video. Google for -The Thing- Wikipedia article. It is a well known case, far from a conspiracy theory.

IF you do not pay a toll, I am pretty sure they can tag the vehicle ID and flag you. Ahhh!
I can lock my vehicle by putting my fob to my chin and thus increasing range to lock it.
Alexa an tell the police what I was doing IF an investigation is in place.
Police can track everywhere my vehicle went.
There IS a song with lyrics. I think someone is watching me.
Can go on. Walmart puts RFID in shoes, underwear, shirts. So watch out you cross dressers LOL

Good day, thank you for your video. Would it be possible to develop a small, RFID tracker, the size of a rice of grain or slightly bigger, that can be inserted under a rhinos skin, and that can then be read from 50-100M away using a reader? To be able to identify a large mammal without having to use ear notching? What tech would you suggest for this type of setup?
