- In this video, what is NFC, How NFC works and some useful applications of NFC have been explained. And at the latter part of the video, NFC has been compared with the other technologies like Bluetooth, RFID and QR code.
What is NFC?
NFC stands for Near Field Communication. It is short distance wireless communication technology. So. when two NFC enabled devices are very close to each other (roughly around 4 cm), then they can communicate with each other using radio waves.
How NFC Works?
NFC enabled devices communicates with each other using radio waves. And three modes of communication is supported by NFC technology.
1) Card Emulation mode
2) Peer-to-Peer Mode
3) Reader/Writer Mode
In peer-to-peer mode, both NFC enabled devices generates the radio wave alternatively and communicates with each other.
In reader/writer mode, devices communicate each other using the principle of electromagnetic induction. The active device transmits the radio wave and the passive device responds back using the load modulation technique.
In card emulation mode, the smartphone acts like the passive smart card and the working principle of this mode is similar to the reader /writer mode.
NFC Standards:
To establish the communication between the NFC enabled devices, certain standards have been defined. And these NFC standards are known as NFC-A, NFC-B, NFC-F, and NFC-V.
Applications of NFC:
1) Mobile Payments
2) Home Automation
3) As a Smartcard or Smart poster
4) Library System
5) Health Care
6) connecting/pairing devices
7) Personal usage

The best channel on TH-cam without any doubt!!!
Nice explanation
Found a Indian TH-cam channel which really provides some information 😂🔥😎😎😎...
Good work bro 🔥😎
Sir very clear explanation 👍, and it will be good if u provide a short pdf of whatever content ur teaching
Nice
Thank you sir, This really helped me especially during my presentation
Your technical information is great.
Can I be so forward and point out to you that; in English you should not pause your speech AFTER an article ('THE' or 'A')!!! It sounds so strange when you pause after saying "the", try pausing before the article. Keep up the good work.
Hahahaha
But that's just how we are taught in Indian schools. So, we can't help it. xD
Sparsh Mecwan that is not an excuse, when someone (a native speaker) offers advice to improve, you can try and modify your speech instead of saying you cannot help it. You can!!!
@@mrtracyut I meant it in a funny way I don't actually mean it, and yes, I definitely agree with you man. Sorry for the unclear phrasing of my comment :(
very irrelevant comment, you’re English is perfect and it was clear. Congrats for explaining such a complicated concept in another language! If @tevaproduction found it strange is more due to their closemindness and microagressivity, I would be curious to see them explain something in indian.
Well Sir its so Educative
This video had so much info. And it helped me a lot. Thansk
It was very useful for a my project, thank you very much.

Can any Android device scan NFC??
Great information. I get clear all my doubt on NFC in this video.
Can I write this information on my blog?
Yes, you can write. And if you don't mind please give the link of this video on your blog.
Ya of course! I'll definitely put your video link. I like your explaining style. Keep it up👍.
One of my little suggestion is that plz explain in simple word. So that an average student can understand better.
Thank you sir for this video.I really understand very well.
Hie, your videos are very helpful. Please make video on Wifi, LCD, RTC, 12C protocol if possible. Thank you.
If only IRS agents were this smart when they called you
Excellent
Great experience
Really great. Thank you.
nice video i want to know how nfc can be used in library
To count the Books...
First step you have to tag NFC ON EVERY BOOK..
SECOND STEP YOU HAVE TO REGISTER BOOK ON THIRD PARTY APP
THIRD STEP - NOW YOU CAN ALOT BOOK BY JUST TAP THE BOOK ...
SOFTWARE AUTOMATICALLY CONTACT PC AND UPDATE BOOK HISTORY...
IN REAL TIME LIBRARIAN CAN COUNT BOOKS EASILY...USING THIRD PARTY APP
Thank u so much.
Thanks alot.. it's very informative!
1 more question, what if nfc card is tapped facing opposite direction? I.e backwards, will the money in the card increase?
@@logithinkearthling3261 your mom's weight increased
Nice one!!
What information can be exchanged on NFC tag?
Just Awesome!!
Tq sir..
Excellent keep going 👍🏻
What is the total cost in India to have this system in Malls , Library ?
Is there a way to provide password protection to nfc. If there a way can you please provide that
Does it eat ur battery if its on all the time?
Yes, it does. But compared to previous versions the new version of android operating system consumes less battery power (if NFC is ON for all time). But still, as it is checking periodically, so if it kept open it will drain the battery.
A very beneficial video on the topic starter. Just a friendly piece of advice: since this video will be shared all over the world & not everyone fathoms the Indian accent, you could make use of reader bots the next time maybe (make it accent neutral). btw ..Did I say this was a helpful video? 👍
Hi. I have a question. What's the easiest way to program the NFC tags using a Mac? And how can I use this NFC to enable another microchipped device/machine?
Make video on Bluetooth architecture
Hi
Could you please help me how to decode the incoming ndef message from nfc device
Thank You
Thanks
Can NFC be integrated with USSD?
Informative video, but the way you place an accent on "the" is pretty distracting.
Aplicație NFC
Jose Rodriguez managed to make an app that can hack ATM's using this technology
if most of people kniw why someone will even search for NFC
Is nfc secured
Oppo f11 pro ma NFC link download

NFC linke send me please
Is NFC always “on” in iPhone ? The concern is that the NFC is always active, emitting 13 MHz radiation, and this electromagnetism or frequency might not be good for people. Many people carry their phones in their pants pockets; imagine constantly having this frequency radiating towards them
Can any Android device Scan NFC??
No, it has to have NFC chip.
Did anyone have the PPT of it
The pauses in the middle of your sentences are very annoying. Please take some lessons English. Cant listen to it
Kromme Zuidvrucht the pauses in the middle of......... YoUr SenTeNCes
Sftu
Engelse lessen nemen zal niet echt helpen omdat hun Engels goed is, maar het is het accent dat beetje naar de k#^ot is 😁
Please take some ENGLISH LESSONS. CAN'T listen to it.
Seems like you also need Lessons of English. 🤣🤣
kromme stfu, if it annoys you don't watch the video.
Pls kindly pronounce properly
Are you Indian?
Acaca
Why is every goddamn tech guide on youtube narrated by someone with a heavy Indian accent? I'm sorry, but for some reason I really have difficulty understanding that accent. Something about the isochrony just throws me off mid sentence, and then all I hear is gibberish for a few seconds, until I recognise a row of words and can follow along again, until I'm thrown off anew.
Why always Indian 🤣
Because unlike foreigners our moms give birth to knowledgeable person
Very good
Thank you.
