Where Did RFID Come From?

The great seal actually had 3 components: a resonant cavity, an antenna, and US personnel stupid enough to accept it as a gift and put it in the embassy.

Thank you for this video. My father, Alfred Koelle, was the first author of the paper shown in the video at 14:37 and went on to be a co-founder of AmTech, a company described in the video. My dad passed away ~10 years ago, but he would have loved this video.

13:48 "A cow is an animal we can get milk from. It moos."
This is the dialogue I came for.

>It's very important not to lose a bomb or two
fun fact: if I had a nickel for every time the US Federal Government "lost" a nuke, I'd have 32 nickels. Six are still missing. Which is not a very fun fact at all, and more of a morbidly fascinating fact.

A precursor to RFID is the grid dip oscillator, which goes back to the early radio days. An unpowered tuned circuit, will actually drain power, if placed near a similarly tuned oscillator, will actually draw measurable power from the oscillator.

I worked on an RFID project in the 1980s. It was passive circuit, that got power from an RF oscillator. The "tags" were employee ID badges, and they needed to be near the cash register, where the oscillator was located, to access the cash box. ID badges sent a serial data stream, that could be detected by the oscillator, as its power draw, matched the data stream. Otherwise, a great early microcontroller application.

Irony, is that I only worked on a barcode project, as part of an industrial control/monitoring system, in the early 2000s.

"A cow is an animal we can get milk from. It moos." I learn so much from this channel

"Returned to the Soviet Union in 1938". I'm not sure if anyone has ever had worse timing. At least he survived.

I met Lev Termen a.k.a Léon Théremin, at his London studio, Camden Town, shortly before his death. Having time to discuss his "Theremin" and it's creation, I leanred many significant things about the remarkable invention and the man behind it, who was learning music at the age of 9 and electricity by 7. It was a forunate moment, for which I am eternally grateful having had such an honour.

I appreciate not having to rewind your videos because the autoplay preview, that happens when scrolling through videos on the YouTube app, doesn't play audio, which can result in missing the first few sentences. Thanks for taking your time and not talking right away.

I gotta say while your productions are among the very best YouTube videos, the RFID story is among the best you have done. I was a teenager in the 70's, and first saw the Knogo tags in Leesburg, Florida at Belk-Lindsey tagging along a clothes shopping trip for my sisters. Of note the tags were installed and removed on clothing items with a machine that released a clip that held a push pin system. . Essentially the memory is that a small burr on the tag's pin had snagged on the garment when the cashier was removing it- damaging the garment and a no sale- happy brother, unhappy sister!. Over the years I have curiously watched the way these tags, very bulky, piled up at the cash registers in boxes and spilled out. Nice of you and your team to give a hard to learn about item and credit to the conceptual process as well as refinement. In the late 80's, I saw the tags on my uncle's dairy farms of 250 cattle. Personal computers even kinda of a new sight in homes, yet my aunt and uncle manage all of the items you mention. Uncles said they mainly compared food intake and milk output. The feeder, read the tag and dispensed varying food to each cow--- my technology awaking #2, #1 was a ATM in 1976 in a Sun bank in Eustis, Florida. As a late adopter, I was still a few years from my first Macintosh. Thanks again for a excellent vignette on RFID. I would like to hear more of the "invasion of Privacy" hurdles you mention about auto tags. Seems unimaginable in todays bio-marker populace.

Great job. Please cover NFC and SIM/smart cards in a future video.

Sadly, for me, Magellan tv shows take forever to impart relevant information. I cancelled my subscription I signed up for years ago. Just very frustrating to pick out small nuggets and have them repeated over and over. The polar opposite of Asianometry, which I love for being concise and pertinent.

As a child, our local public library was probably my first encounter with RFID. They had tags in all the books, to ensure any book leaving had been handled by a librarian who could drop the books over the readers and not set them off. But it was purely anti-theft. They still had to check out the books, using the first barcode wand I can recall seeing. Today, I use a machine with various chemicals that all come in relatively identical containers. The machine has readers for every chemical and every jug of chemical has an RFID tag. Theoretically this is supposed to prevent an operator from putting the wrong chemical in the wrong place. It mostly works. But people have still found ways around it, without even trying. Make a better system and you make a better idiot, as the saying goes.

RFID tags were used in the Netherlands years ago - to track blood bags in hospitals. It allows blood to be delivered to the right operating theatre using the 'just in time' approach (like modern car manufacturing). The system tracks each bag via RFID sensors in the walls to ensure none are wasted. I had a postgrad student who pioneered the methodology for this a couple of deacades ago.

Weekly dose of Asianometry does wonders to the human brain

Seen this at Decathlon a couple of years ago. Monobrand stores make it easier to adopt RFID checkout rather than multi-brand. Ikea next? )

In 1977, a company in Santa Cruz California named "Identronix" made an insertable RFID tag for cattle. This was sponsored by a leather tanning company that wanted to prevent cattle hides from being defaced by branding. This was an "active: chip that used power from the interrogator to activate a microprocessor-based logic circuit to send back a unique code.

Dude, your presentation is great. You took a dry-ass subject like RFID and made it interesting.

There's a guy local to me that developed a system that users embedded wires to measure internal temperature of items. I believe that system works by RF stimulation then detecting the magnetic field that varies with the temperature of the embedded wires. One apparent application is in manufacturing of composite materials which often need very accurate control of temperature during curing. I machined some insulators for him that went into magnetic "antennas".

My friend's dad was mentioned in this video and im beside myself. What a surprise haha. They even have a picture of him!

Amazon just recently started closing down their grab and go stores (which were apparently powered by oversees offices that had employees manually reviewing everything).
