This is a really quality video . You deserve more subs. Keep it going
very straightforward and informative, thanks!
lekka video dude!! I've just gone into RFID sales and just got destroyed on a call.. All my training material is in abbreviations and not much description.., so this helps me a ton
Johann, I am so grateful that this video has helped you man. Truly am. I am looking to make some more videos soon as I get my studio back up and running. If you need any clarity on NFC Things. Let me know so I can put some contents together for others who might be asking similar questions! I hope you SMASH those RFID sales man!!!

Great presentation. Well done.
this was informative. Thanks!
Well explained, thanks alot
Awesome video!
Thank you is great to know what it is better to use
Great video
If you search RFID VS NFC this video is 2nd, first being one by blue bite.
I found this video much better. Cheers!
Thank you! Hope it helped.
Really informative 👏
Thank you awesome understanding
lovely video bro! Thanks!! 😀😀😀😀😀😀
So if i wanted to duplicate an already existing nfc tag with some information written on it i can simply do it by tapping my phone and using the app you mentioned? Please help @Bren
I found this extremely helpful. I have an NFC tag I need to scan and the droid I have (Galaxy A03S) is supposed to have a reader. But I can't find it nor does it give me an option to use an app. Am I missing something here? I thought NFC readers were on new phones only but people keep telling me it's been around a while. What phone are you using? Are there cheap phone options that have this ability? Thank you in advance.
the explanation was really great, but may be unexpected, but great
I have an app in ionic framework IOS and android app in which we create nfc read and write function. In Android NFC read and write function will be work but in IOS read and write function will not be work.how can you help you bro
Hello, Do NFC tags emit any kind of radiation that could be harmful when in close proximity?
Is there any way I can add an RFID card on my iPhone ??? Please help.
How do we clone a NFC or RFID card?
Make a detail video on it please..
Can hand held RFID readers read ID card or cards? Thank you. :)
is there any way to make them un-rewritable?
Bren, thank you for great video and detailed explanation! So you know by chance if there is a way to amplify the NFC chip slightly? So that my chip can be detected within a 1-2 meters of distance?
Hey there!
Its quite difficult to be able to amplify this signal. The limited range of NFC is actually a security feature. The only way you could do this is by using a larger antenna and a module powerful enough to output to this antenna (They do exist) but even at the maximum, you would only realistically get 20-30cm out of it.
If you're looking to do very far range with RFID, I suggest looking into UHF (Ultra-High Frequency) Tags. These are commonly used on livestock ear tags, warehousing and clothing stores, with a UHF Reader you could do up to 10 meters.
@@BrenMaartens for that kinda long-range should we have a special reader or can we still read those tags with our smartphones’ NFC abilities? If not what is the maximum range can we reach with general NFC modules with our daily phones? Can we increase this range with just changing the NFC tags type/frequency or It’s totally depends to reader? And thank you so much for this video👌🏻 It was really informative
@@premium2554 HI Kubilay!
Unfortunately you will need a special UHF reader to read UHF tags as they work in a much higher frequency. Our phones are only limited to 13.56Mhz (NFC).
That being said, since the antennas in our phones have a limited size, the range of the NFC transmission is limited to only a few cm from your phone. All tag types will respond with the same distance.
"All tag types will respond with the same distance"@@BrenMaartens simply not true at all. Bigger tags have a bigger read distance.
I have no idea if you can beef-up a reader, but what you said about tags is wrong.
@@MrRedstonefreedom Hey man! you're actually correct. Generally speaking if the tag is bigger, the antenna is also bigger resulting in a further reading range. However it's most effective if the transmitter antenna is larger (in this case the phone) but yes, bigger tags are bigger antennae and therefore slightly better read distance
I don't know if it is possible, but maybe you know:. Suppose I create an application on my phone , and I want the app to check an RFID (or any other tag) to check any rfid Is it possible that the app checks this without momentary permission (so automaticcly check when reading an RFID, if it has anything todo with the app), or do you always need the users permission in that moment? I assume that if this is possible you give the app permission to check all RFIDs that are offered to the phone, which sounds unsafe, but also sounds kinda handy. Does anyone know what the permissions logic is on andriod/Ios systems?
Hey Guys, Thanks for all the feedback. If you're looking for a quick video on how to make your own NFC Business Cards. Check out my latest video here:
ruclips.net/video/QBaoms_lkxc/видео.html&ab_channel=BrenMaartens
Which one does the hepatic feedback when transmission is complete?????
Hey there! The Haptic feedback when transmission is complete is app based. Depending on which app you use, it will make use of Haptic Feedback. I recommend the apps I used in this video as they are the most user friendly to start with.
In general (earth like conditions), high frequency waves travel less distance than low frequency waves
PLEASE HELP ME ANSWER THIS🥺
I am a programmer and my client wants to write fingerprint, image, and names of its staff into a card.
Is it possible to write the above details into a card?
What is the largest size a card has? (please mention the name of the card)
Nelson my man!
You won't be able to write that much data onto the card. You can tell your client to message me if he has a problem with that haha.
The only way you can do that is if you have an online data base that has all those staff details. Then have your card refer to a unique ID of each staff member in the database. So as you can the card, it's linked to the Staff information from the Database.
The biggest card you can get is an NTAG216 which is only around 800bytes
Can I clone my bank card with a nfc reader then write it onto a little chip that I can implant in hand ? Thanks
Do u know how someone can create an NFC reader in their own app?
I don't know much about iPhone but there are plenty of tutorials online for doing this in Android Studio for Android based apps. However you will need to know a thing or two about NFC Chip Types. It is worth Investigating.
Hello, may I ask what kind of chip is often used in residency permit card?
Hi Haung, Most likely its going to be a 125khz chip. So probably TK4001 Chip.
@@BrenMaartens Thank you. I know it is possibly RF high frequency one. Why it is not S50 milfare 1K?
Could I put these tags inside my work tools to identify them? If so could someone just write over them? Very interested in this product
U can download nfc tools app from play store, write the data u want, and then u can lock them (u cant rewrite them anymore) or lock it with a password which allows u to unlock the tag if u want to rewrite it.
Yes, this is what I have done. You can get them in a small sticker. Once you write your data, you can lock the tag, which can't be rewritten. I used a website with my contact info that tracks when people click the link.
There are NFC/RFID writer applications that can encrypt the data, same as credit cards with RFID, this then can also be locked to writing without decryption. It could be brute force overwritten with decent difficulty with basic encyption, up to 256 and advanced encryption such as HID uses in some instances. If you're asking for convenience of reusing, yes, you can re-write over most of them.
I tried using NXP app (with Latest Android Phone) to read multiple NFC building gate card and tags, the app doesn't read any code or anything. Not sure if I am doing something wrong or the card and tags I am using are not exactly NFC.
do both 13.56mhz nfc and 125khz rfid read credit cards ???
Unfortunately not. Bank Cards that support Tap-To-Pay are only 13.56mhz frequencies
Hi, is there any way to sync data with excel/GD?
Please 🙏 i have alot of questions for you how can i communicat with you ❤️❤️❤️
Hi Bren, Thanks for the info. Where did you find the 10mm NFC Sticker tag?
Hi Josh! - I got them from a place in South Africa called Netram Technologies but they don't ship internationally. You may need to ask local shops that sell RFID in your country if they can order them for you
if I use NFC for public ads (not personally holding), is it possible someone can access to the NFC and change the content I made originally ?
Hi Raouf,
After you've written to your tag with the content of your choosing, you can then lock the tag using the same software you used to write to it. Locking the tag prevents anyone from overwriting over your content.
It will then be permanent
Hi , can i copy rfid on phone to use my phone without card
Hi Moayad!
Good question, I know this is 100% possible with regards to hardware - Your phone is physically capable of doing this but I think the software that allows this is very hard to obtain because of security reasons. I am not aware of any software right now that will let you do this. If anyone finds software, please let me know :)
can NFC tags open and close a electrical contactor ?
Certainly, However you would just need to find an NFC compatible electrical contactor.
If you don't have one, you would need to just put together an NFC reader and a microcontroller like an Arduino.
When the NFC reader detects the tag, it tells the Arduino and the Arduino sends a small pulse to the coil side of the contactor to either open or close it. Quite an awesome use for it!
Are you talking only about passive RFID ? Because I've seen that RFID can have other frequencies other than mentioned in the video and has a wider distance
Hey Batman! :D
Yes of course you do get other frequencies in the RFID Range. Just in the passive range it can go from 3 - 30 Mhz for Low Frequencies and up to 300Khz for Ultra High Frequencies.
These frequencies can also be different when we start looking at active tags which have a more niche use case.

Can you use android smartphones to copy rfid key cards and use them with your phone?
Hey man, unfortunately it won't work with Android phones unless you have the phone rooted and using special apps that I can't endorse.
You can however so this with RFID card using a device called a Flipper 🐬
@@BrenMaartens what android app?
What kind of watch are you wearing
Hey Mike, It's the Samsung Gear S3 Classic I think. I got it many years ago but it's still my go to :)
So the phones are NFC readers, not transmitters. So there’s no way to use NFC on your phone to send information to and Arduino with an NFC reader?
Hey Terje!,
Actually the Phones are both NFC Read/Writers. They can do both.
You can actually send information from one Android device to another device. Very long ago Samsung hand a feature where you could put phones back to back and send files. They called it "S Beam" - There are newer version of that protocol now. Maybe search "Send Data via NFC Android Phones" - I am sure there is someone who knows a little more than me about the Data Transfer part
@@BrenMaartens, Thanks. I’ll try to find it.
Hi, can we add RFID to iphone ?
Yes you can use the iPhone for NFC but it works best with Mifare Classic Cards.
Bren can you get the nfc in the form of small chip?
Maybe like how the nfc chip looks by itself when not on anything
Hey Roberto, I mean I've never tried but I'm sure you can get them. I know personally my supplier of chips sells them but you need to have a compatible antenna built for it to actually receive power.
Hey where can i buy NFC stickers in South Africa
Hey Gadi! - Have a look at www.netram.co.za under the Communication Category
Why does NFC card stops information transfer from other credit cards?
Hi Harsh, do you mean the transfer between credit cards? Or how do the NFC blocking cards work?
@@BrenMaartens Hi Bren, I want to know how blocking of cards works. Thank you in advance 😊
@@harshpatel11094 I’m also wondering about it, did you get any information???
Which iPhone does support NFC
iPhone supports NFC from iPhone 6 onwards. However iPhone 6 only has partial Support. It can do NFC payments but cannot read and write custom cards as shown in the video. The models after the iPhone 6 will do it all. Lastly, iPhone only supports certain makes of NFC Cards. (ntag or Mifare) so just double check with your model before you buy.
@@BrenMaartens I have an iPhone Xʀ
THANK YOU for your help
do they work on androids as well?
Hey my man, Yes- This exact video was filmed and done on an Android phone
@@BrenMaartens hello bro, i use OnePlus 7. And getting around 50 RFID tags( either in card or keychain) for USD 5 on Amazon. Should I get it. I may use a few with Tasker integration.
Will the RFID tags work with my phone??
@@VinaySPujari Hey man,
Yeah you can use Tasker with those cards.
But just be aware of the difference. Make sure the cards that you buy are specifically NFC Cards. Preferably NTAG version.
RFID Cards (125khz) will not work with your phone.
Is NFC is inside gsm card?
Do you mean like a cell phone SIM card? There is no NFC chips Inside those cards
@@BrenMaartens yes
@@BrenMaartens is nfc inside ATM card sir?
@@adiflorense1477 Yes that's correct. They use an encrypted NFC protocol for Tap to Pay feature on ATM cards

You're the MVP. Thanks so much man! 😁
Thanks for the information. Less music will be better
Which Android does support NFC?
Yes
all of recent updates
Cool huawei p10
I have an nfc in the back of my hand with a tattoo of the nfc
That's amazing Joe! 😅 what do you program it for?
@BrenMaartens it has multiple bits of data but the first 2 banks store youtube links to "Rick Ashley never gonna give you up" aka rick-roll. The 2nd is a link to a private RUclips video of me walking through my medical records it's extensive as a 2x cancer survivor
@@ZoeyR86 What a legend!!!
How do people read it, via phone? How do you switch between which video link the phone reads when you bring it near? - Like how do you not accidentally rick-roll your doctor?
I just wanto to open my door thru my phone without me using the physical card
Good question Luis, It is a little trickier than it seems. Because the reader on your phone is an NFC read/writer. You might need to use special software that makes the phone act as a Card and only output a UID number. But this is quite tedious because every time you want to open the door you need to open an app on your phone.
If you're okay with that -
You would also need to use an NFC Reader on your door which is connected to a magnetic door lock. Every time the NFC Reader detects the correct UID. It disengages the Magnetic Lock for 3 seconds - Enough time to open the door and walk.
@@BrenMaartens thank you I was looking for this resume
Totally wrong...
RFID 125Khz has a longer read range than 13.5Mhz.
NFC is also RFID
You forgot nfc implants.
Hello, thanks for video. What is the relation between NFC and Mifare? If there is one....
Thanks!
Hey! Good Question! Mifare is a brand of NFC Chips made by NXP. You get Mifare and NTAG both owned by NXP. They can both used for the same purpose. One type may be suitable for certain applications than others such as high security or ISO certifications
@@BrenMaartens Thank you again! Now it starts to getting clear in my mind ... Newcomer on topic! 😀
