- In this video, RFID (Radio Frequency Identification) Technology has been explained.
So, in this video, what is RFID, what is inside this RFID system, how RFID works, and the application of RFID have been explained.
What is RFID?
RFID is the technology that works on radio frequency and it is used for the auto-identification for the different object.
The RFID system mainly consists of two parts.
1) RFID Reader or Interrogator
2) RFID Tags
In this RFID system, this RFID reader continuously sends radio waves of a particular frequency. If the object, on which this RFID tag is attached is within the range of these radio waves then it sends the feedback back to this RFID reader.
And based on this feedback, the RFID reader identifies the object.
RFID tags:
Now, three different kinds of RFID tags are commercially available.
1) Passive tags
2) Active tags
3) Semi-passive tags
These passive tags do not have any power supply. They used to get their power from the incoming radio waves from the Readers.
While active tags have a power source for their internal circuitries. And for sending the response to the reader also, it uses its own power supply.
In the case of semi-passive tags, they have a power supply for internal circuitries, but for sending the response it relies on the radio waves received from the Reader.
Operating Frequency:
This RFID system is mainly operated in three frequency bands.
1) LF: Low-Frequency band
2) HF: High-Frequency band
3) UHF: Ultra High-Frequency band
The exact frequency of operation varies from country to country.
Operating Principles:
Most of the RFID systems operate on any of these two principles.
1) Load Modulation
2) Backscattered Modulations
Applications of RFID:
1. Institutions: Library, Hospitals, Schools, and Colleges
2. Transportation and Logistics
3. Access Control
4. Sports
5. Animal Tracking

If I hear a Indian accent I immediately know I'm about to learn something
Orhhh yaa
Lol not always especially the scam centers lol they may know the words, but not what they mean. Lol but if it's an Indian accent, like this guy he's spitting facts
When I hear an indian accent I immediately close the video
It's a bit hard on my ears. Not because i don't like the accent it just reminds me of the scammers all the time 🤦♂️ so annoying.
I immediately know I should turn closed captions on.
I specifically came here because no one really talks about how RFID does load modulation. You did. Thanks. Very informative.
Nice information. Haters are just gonna hate. We are here for the concepts not accents
Honestly I'm here for both. This guy's voice gives me thicc ASMR :)
Lol
I adore your accent.
Very true
You must be a Nigerian based on your comment.
We are working on an project in which we are required to use RFID but there's no proper videos explaining the concept....you explained it so nicely and it was really smooth to understand the concept...thanks for your efforts.👍🏼
Jesus loves you
I am curious about how the project is going ,because my work related to RFID too ,maybe one day we could cooperate with each other
@@halliehe202 surely ...i am an Commerce student but also interested in stuff related to technology.
@@shritej_mali My major is commerce too,haha
@@halliehe202 cool
I now better understand the how the tag (with its load) modulates the 13.56 MHz reader's magnetic field to send its data back to the reader. Thanks for clearing that up!
yes but many people do not know how to understand spoken English, there are about a million dialects the way English is spoken, this chap in the video may not understand you any better. I understood every word he said plus the fact is I work with RFID and could not find any faults in the technical aspect of what he said and his explanation was best ever .
Thank you very much, this was just great, and a super clear explanation! I’m not a native English speaker and I could understand it just fine. Your accent is amazing! I hope you do not get bothered by the fools who cannot appreciate the time and effort you put into this, and all they can talk about it how you speak. Here’s hoping they will enter the 21st century one day. Thank again for your effort.
I'm shocked at the responses of people here, I simply can not believe my eyes. Like you said we can only hope that they attempt to step into the 21st century era
@@lillymek3224 the end is near. :/ sad 18 yr old girl
Stick a d!Ck
JESUS LOVES YOU!!!!!
Perfectly explained just enough to completely understand the basics.
Jesus loves you
Thanks- this was a really good explanation! I was not understanding the difference in passive vs active tag until now. Passive tag is what a vet implants in a dog. Active tag is what we hook to dog's collar or child's clothes to track them on cell phone app
Active tags generally are self-powered relying on their own power to send a signal to the receiver, semi-passive rely on radio frequency of the receiver to send signal to the receiver & have limited range whereas passive tags have no power & entirely depend on the reader is what I've understood.
Great explanation of the basic principles underlying the RFID technology
Thanks for the informative video. I have a question: 5:24 I always thought that higher frequencies are more fragile to attenuation and therefore their range is smaller than low frequencies ? Is it wrong ?
thank you, really appreciated as a student who is gonna do something with RFID
Ur method of explanation is excellent. It is very easy to understand and u've covered every topic order wize. Its really impressive. Keep up the good work.
Thank you for concise and clear explanation. Excellent. Good if can make additional you tube videos for few related topics - 1. Material of the Tag ?? 2. Environment under which Tag and Reader are working including what to do and what not to do to increase the performance 3. Impact on the range /distance between Tag and Reader of the environment ??? 4. I am sure other readers can add to my list
This is a great video! Much clearer about what is happening on the card and also the reader.
thank you for gave me a great explaination of RFID
Great insightful introduction video for RFID.
This is precise and on point...nice work you can be a greater professor.
thank you really much for this video! Really clear! I have a question: Can we use the FFC RFID with high frequencies and detect how far or how short the RFID tag is from the reader based on the intensity of the signal?
FCC is just a regulatory body, you can detect the range of the RFID by using an Ultrasonic sensor with a preset distance calculation or microcontroller with RFID wave data for interpretation of signal parameters.
your effort on RFID information is appreciable.
Question: can you read an RFID tag and write it into an NFC format that an RF ID reader can communicate with?
Good entry level presentation. Accent was thick so I turned on closed caption which was video publisher generated and very thoroughly done.
As an American English user, I am always happy when people of other cultures take on our language. And visa versa, i.e., my son is teaching Science at a private academy in China and has become fluent in Mandarin to do so.
Languages are cool...
Ahhh yes, English is American.
@@TK_Orange ahahahhahahahahah
Superb ! Only important things covered and no blabbering ! great
Thank you for a very clear explanation. I wanted to understand this technology so that I would know how to block those who want to steal credit card information. This got me started with a basic understanding of the way RFID works.
I see the comments about your accent. It is rather different than mine. I live in the Central Valley of Californian. I am, of course, used to the accents I hear every day. It would be helpful if you slowed down when you speak. But I solved the problem by turning on the close captioning. It did an excellent job of translating your speech into text. I could also have slowed down the play back of the video. But that wasn't necessary.
Again thank you. I have subscribed and activated notifications. I look forward to your future offerings.
Thank you for the great video, what device you recommend to disrupt/jamming RFID signal?
Thanq brother,very well explained.
One of the Best Explanation on RFID....
Nice pic
Just wanted to know if a HF can be feasible to mark and monitor smaller plants to trees.
And how much does it costs?
Also, is there any better and cheaper way of tagging a plant?
Explained very well. Thanks for this wonderful video.
Couple questions:
1. Do all tags have the same ID that the reader recognizes or are there different ones programmed into the reader to detect?
2. How do tags get deactivated by rubbing on a black looking thing like in a library when signing a book out?
1. Each tag has a different ID and the reader is programmed with all the IDs it should detect.
2. Tags are not deactivated, the reading system is told not to act upon the particular IDs
@@MilanTharakaMusic For #2 what does rubbing on a black thing do exactly so the programmer doesn’t read it?
Awesome explanation..really helpfull
thanks for information
i have a question can we use passive rfid tags for any liquid level .
means if high level it works and when liquid level is low it expired.........
Very helpful! Curious about the tags found on commercial products, like a "smart" water filter for a refrigerator. If I buy a RFID sticker and copy the sticker on the filter with my phone. Can I simply write that to the new sticker with the app on my phone and expect it to work? Or is there more at play here than just using a new sticker?
Best video of RFID seen yet... the most detailed description....
Very well explained! Thank you.
Wow ! Very lucid explanation with sufficient graphics of RFID tag. Thanks a lot.
Next time some images of real RFID tags etc will help.
Great explanation. Thanks for sharing❣️
great work
congrats !!!!!!!
Hello AAE, thanks a lot, now I understand how rfid works. Just one comment/question on distance travel wrt frequency (ts 5:13). I thought one of the basics in radio waves is that lower frequency travels longer than higher frequency. So i'm wondering if you had it the other way around. Appreciate if you can clarify, I could be wrong.
Same doubt here
Really helpful. Thanks for the overview!
love your video and comments on the RFID signals, never know about this before i watch your video, was usefull to me !
thanks a lot, for a software developer like me, this is video is the best I hav seen about RFID intro!
Thanks
Superb Presentation
Hi! Can I tell if the rifds can contain frequencies (hz)? How long do they stay inside? Should you rewrite them how often? What is the writing mode for frequencies (hz)? Thanks
Thank you for the Best Video. It is very useful and the explanation of the RFID is nice and easily understandable.
I'm very grateful of your tottally clear explanation. I'm very very grateful! I'm not english native speaker either, but i understood everything. Thanx a lot!
How we can interlock this technology with Programmable Logic Controller ?
Nice video presentation, Sir, My question is,What are the most frequent causes of RFID interference problems and ways to avoid RFID interference problems. Thank you very much
Wonderful explanation, your videos are consistantly the best!
Question:
How easy is it to clone an rfid card?
Can you just read the ID and make a new tag with the same ID?
This seems very unlikely for acces batches etc.
we need a video on how to clone cards and what tech is the best to use for that specific cloning method
or does anybody know and can point me to the right video on how to?
Thank you very much for time saving. You explained super-easy and clear way. It really helped. Thanks!
I understood the entire video content. Thank you so much!!
Great explanation..Thank you so much...
Well done illustrations. Pretty well communicated also. Thanks for your effort.
Bless you brother
Great quality video. I appreciate the content very much and it has helped me alot. Your english is fluent and easy to understand. Thanks!
Thnks for uploading this video
Its help me to understand about rfid completely & no doubts
Excellent review and I am the owner of four electric locks with three RFID TAG at 13.56 MHz, I would like to use the same RFID tags to turn on and off the electricity through an RFID card reader (used in hotel rooms) always at 13.56 MHz? In your opinion, can the RFID tags be read by both devices?
Ooo so this is how the fastag on our cars works, finally understood 😂 👍
Very good teaching of RFID thank you so much
This is very useful thank you for making this
thanks a lot for the nice explanation, can you tell me how to use it in shops?
It was really helpful.. well explained great job..
Wonderful video. (Thanks)
@@juliusbrayden5101 💪👍✌
Jesus Loves you!!!!!!
Who wants a quick clear explanation regarding RFID working, classifications, application etc. , this might be a recommended video.
Thank you for the clear explanation.
*Superb explanation 🔥*
Hey! Nice video. However, there is one thing i was conserned about. Shouldn't the distance be higher for lower frequency and shorter for higher frequency? I am quite sure i learned it in that way
Jesus loves you
and that just helped me learn what is the difference between RFID and NFC, turns out to be one kind of RFID
Excellent video and very nicely explained. Its obvious you know the stuff and can teach well.
Nice Explanation..
nice presentation !
thank you for the the amazing opportunities first its advantages and the dis advantages for those who are marked with RFID .My question what will happen to the red blood cells ?
Great explanation!
MARK OF THE BEAST
Holy hell you got to be kidding me
Hahahah seriously?
True
Agree.
Well done !!!
thanks for the info. very good and clear explanation.
Nice explained, thank you
thanks
congratulations
I watch ads to support you financially. You deserve to watch ads.
NICE EXPLANATION,USEFUL.
Thank you very much Sir, good job.
The speech is simply too fast for a decent presentation. He needs to slow down, breathe, pause, wait for the listener to catch up.
The explanation is for big brained Indians and Chinese, not dumb ducks westerners
Thanks
Sir pls what kind of signals suits for Automatic Fare payment I think low frequency right ?
Great explaination
I found one of those rfid in my t-shirt
Guys help me
What does that mean !
Some stores use it to prevent theft!
No it's to wish Satan opon u because stores are evil 😂👌 jk I aint Christian it's just a anti theft device
A just ideal explanation, just please talk slowly!
It's a great explanation. One question ,
Will RFId cards for kids is harmful and if so which range is safe also is there any other card to suggest
Great video. Very explanative and easy to understand. You are dope man 🔥
good to know and many thanks
That's why we can not steal from mall
Thank you so much for explaining the RFID technology so well. I am working on a project where I have to use ultra high frequency to connect Apple Pay to a RFID reader. the distance is approximately 10 to 15 feet. Please let me know can it be possible if yes how. I live in US you could contact me.
Thank you for the thorough explanation. In my opinion, your English is excellent. However, if you slowed down just a little, it would be easier for me to comprehend. Regardless, I just replayed it until I got the gist of it. Well done, I'm now a subscriber!
A very good explanation, but please be more aware of the use of the word "so"...
Richard Jensen
We should understand the subject not his accent
This is only understandable at .75 playback speed lol
Jackson Cobb to be fair the accent is thicc 🍑 but his english is pretty spot on
Hello bro! Really nice video! Can you make a seperate video on "Load Modulation"?
How it sends back the signal..?
Nd how load get matched or mismatched in working on UHF... Can please explain this...??
Way too Fast dude!!!!
Do not put this in your body!
satan, 666
I agree DONT DO IT JESUS LOVES YOU
Why not?
Ima do it
Put it in bum
Amazing video. This was well explained. Thank you!
DONT TAKE THIS
@@littlesam6280 what do you mean? 😅
ikra ahmed it’s possibly the mark of the beast and Jesus does not want you to take that otherwise you will not have eternal life
Hi Thanks for your video. Can we use an UHF Reader to read HF tags or can HF tags work with UHF Readers?. i.e. can we use Omron V680 Series tags with Honeywell UHF Readers?
