RFID Roundup!

[@offendingshadows9118]

Your timing is psychic. Am about to do an RFID project and needed this!

[@PlayfulTechnology]

Oh cool, well hope you find it useful! Please do ask if I can be of any help :)

[@Kaasgeelheid]

I started the video not knowing anything about implementing RFID with Arduino and you basically shared all the basic knowledge in a very structured manner to get started. Thanks & kudos!!!

[@thespencerowen]

Thanks for the information. The PN532 has further issues with I2C where it uses clock queuing and makes it very unreliable. I spent days on it before I went back to SPI

[@hudsonsoares6752]

Thanks a lot for all the information in a so clear and concise manner!

[@scythascytha2849]

Thank you so much for explaining RFID to me. This was exactly what I was looking for. Also, the idea of using RFID as sort of puzzles is a great one. I'd like to try that as a 5th grade teacher.

[@EmmaMaryTaylor]

Thanks very much for this, got the RC522 set up very easily to my Arduino Mega, was struggling with the RDM6300, now happily will leave that part! Will definately pick up one of the PN5180 to give it a go! :)

[@miguelangelplazaluna5092]

Wow !!! es justamente lo que necesitaba... Excelente video y muy claros.. Muchas Gracias desde Chile !!!

[@TheDevilOnLine7]

FYI, the MFRC522 arduino library has a function to boost the antenna power so you can read cards from about 10 cm's from the reader, so no need to solder!

[@PlayfulTechnology]

In previous versions of the library, the SetAntennaStrength function had no effect, but I will go back and try it again - thanks!

[@latestsolutions837]

From where to buy PN5180 in India?

[@bibel2k]

As always, great video. Very informative and well explained. Cheers!

[@harshbenahalkar4815]

Can I use a PN5180 scanner to detect multiple RFID tags?

[@friedmule5403]

4:30 I have just, by luck, heard of a unit, called a CAN BUS it may be the perfect solution, it can be made to talk to Adriano via only two wire but can handle insanely many inputs, like many RFID tags at once.

[@latestsolutions837]

I want to connect an external antenna to the PN5180. Could you please help me achieve this? I'm having trouble with it.

We used the RDM6300 in a 4 RFID prop and we had a lot of problems. Finally we only got to recognize the RFID one by one and we could not know if the tag had been removed

[@mytechlearning]

Çok bilgilendirici bir video olmuş. Çok teşekkürler. Mfrc 522 kart ile bazı kartları okumada zorlanmıştık. Bulabilirsem ben de Pn5180 kartı deneyeceğim.

[@mjyanimations1062]

the first module has its own uart and so does the usb to serial chip on the arduino. so you don't really need to emulate a serial with the microcontroller. just flash the arduino with a blank sketch so the serial port is unused by the microcontroller. then you can connect the serial pins to the rfid module and the module will speak directly to the usb to serial chip. no microcontroller involved.

[@jackt3603]

Thank you for posting the video, it made it easy to understand the differences between various readers out there. I need to place a number of readers in a grid, let's say 10x10. Each of the 100 readers needs to have the ability to read a tag that will be brought close to it. What would be be best solution for my project? Can I make smaller atnennas like you did with the RDM6300, and then connect them to their respective board? The issue I'm having is that the readers will be pretty close to each other (around 1.5 - 2cm apart), and thereore I'm not sure what would be the best solution to solve this issue. On a separate note, is there a way to check if the tag is still in the proximity to the reader? You mentioned that the reader only sends data once, when the tag is near the reader. Is there a way to ping the tag with the reader let's say every 10 seconds, to check if the tag is still in close proximity? One last question, do electromagnetic fields affect the ability to read the RFID tags? Any input would be much appreciated.

[@btechstuff]

Can these read multiple tags in the area?

[@zeca1471]

Hi, Could you give me the code used in the PN5180, I'm looking for a simple code like the one used in the video ? 😃

[@Andrew-ps9zp]

I read that the the logic pins are 5-volt tolerant for the RC522

[@PlayfulTechnology]

Not according to the MFRC522 datasheet they're not. www.nxp.com/docs/en/data-sheet/MFRC522.pdf

Great vid Paula I’m putting a rfid reader/writer onto a drone and want to read long range tag read and relay that info back to myself how do I extend the read range sir ?

[@MrLuis9916]

Very good video, it helped me so much for my graduation project. I have a question tho, mounting points on the PN5180 are the same as RC522? I need to 3D print a case for it but i can't get to find the datasheet for the PN5180 module, would appreciate if you could help me with that.

[@felipevalles3831]

Cuántas tarjetas puede leer al mismo tiempo??

[@ytfp]

*edit*Perhaps the below might not work if the sensor does not constantly output the card number if held to the device and I am misunderstanding so adding this edit in in case the module does not constanly spam the number while being held** think your RDM6300 issue can be solved in software, if a tag is detected simply start a timer and poll at every x, another solution is while( card number=true) do this else, go back to polling, another solution start action 1 ONLY when card number=true for at least x seconds or minutes. For the more complicated array of readers don't read card 2 unless card one is true, or card 1 is true for x seconds. The whole idea is just like a flag system works only your flag is time, essentially the difference between a short press or a long press on button to produce two or more funtions with only one button, time duration pressed=what function to fire. Off to watch the rest of the video...

[@ukirfan]

is it possible to modify a "passive" rfid tag to detect moisture , humidity, possibly shorting some pins soldered externally to the rfid chip ?

[@lutzmuller5703]

@PlayfulTechnology, which system would you recommend to me if I wanted to use it for a model railway? I'm just interested in identifying a locomotive. It should only allow small distances. Would you use the MFR C522?

[@ap_channel4090]

Sir, is RC522 can read 125khz rfid??

[@fifofinho1]

Hy friend , i need to read a tag in 2 meters from the rrader its it possible?

[@joshuaolakanla3993]

Please I successfully built it using the pn5180, but my range is only 10cm and I need about 20cm

[@محمدبنماضي-ث7غ]

Ok, if the reader is behind a plate of iron about 5mm thickness, can it detect the card ??!

[@thevoice4758]

Hi, I am using the 125khz HID INDALA card. Can I connect one of these card readers to my arduino to perform this action ?

[@CamChadDoIt]

Do you have any schematics or suggestions on how to wire the PN5180? I am using an Arduino MKR WiFi 1010 - any help would be hugely appreciated!!

[@mumbles1justin]

Great video! I noticed most of the readers appear to be mounted using screws. Doesn’t the metal from the screws cause some interference with the magnetic flux in the coil antenna, shortening/ influencing the read distance?

[@ismail_aydemir_youtube]

Thank you very much for your explanation. I have the rc522. Reading range is not very important. But; I can try l1 and l2 you just described. I want to ask and if I beg; Do you have a connection method to ensure stable operation of 10 out of rc522? (connecting resistor to sda and sck that I see on the internet. I haven't tried yet. my material will come today) 2-2 comments; When I want to work with multiple readers, is there a serial number or device name or address path indicating which address I read from? how do i get thanks

[@pinqizhu5761]

Thanks for the tutorial ! I have a PN5180 and I wanna the board to tell when I removed the card just like what you did in this video, but I have problem finding the source code for this function, could you tell me where I can find it? Thanks !

[@harshkumar-so6xr]

Sir, Can we use external antenna in "PN5180" Module to increase its reading range upto "1 Meter" & Is there any RFID Read/Write Module for "EPCglobal Gen2 and ISO/IEC 18000-6c" available in market under $20. thank you.

[@krishan8785]

thank you sir , i'm asking if there is an uhf module reader for arduino ?? i have a project , i need to read tags about 5 meters away please help me ! thank you

[@N1ghtR1der666]

can you connect a better antenna to any of these?

[@daniellewis1511]

Has this area improved over the past 5 years? Is PN5180 still your preferred, or are their newer options?

[@PlayfulTechnology]

PN5180 is still my general-puspose RFID of choice, yes. If you want something with _significantly_ longer read range, check out EPC Gen2 RFID, as demonstrated in kzbin.info/www/bejne/paDIg4l3oJd5f5Y

[@arianaescalantemarcillo4322]

Hey! I would like to know If I can use RFID RC 522 with avoidance collision. I want to read several tags at the same time and I would like to watch this collisions. It's for a college project.

[@PlayfulTechnology]

No, I think you'll need a better (more expensive) chip for that - the RC522 only provides pretty basic read/write functionality and I don't think handles collisions.

[@charlieji8781]

WoW this is extremely helpful!

[@dangooch5267]

I think the long range detector is what I need for my project. What I need are small chips without any card. I once saw a man who had RFID chips in a dime sized plastic laminate. Anyone have a source compatible with that reader?

[@rachelking2371]

Hello, is there any way to directly contact you? I have a project for school that I really want to use the PN1580 sensor in. Unfortunately, even now, getting my hands on one will take a long time because all of the one's I found online are being sold from China. Is there any way I could perhaps one from from you, if you live in the US? I'd assume it would be faster to get it from US instead of China. I'm willing to pay up to $35. Any thoughts? So sorry to solicit you, but I'm desperate because this project is due by the 30th.

[@korosha]

Thank you for this video. Very useful. Any recommendation on easiest way to program a reader to read multiple passive RFID tags, e.g. multiple books on a shelf? looking for the best capable RFID reader + python SDK, preferably using Raspberry PI, else Arduino ?

[@AaronMayes]

I've been trying for a few days to make this work with RC522's, I've followed the wiring diagram in the video description which includes two logic level controllers, and I can get all of the RFID chips to each work independently if I remove power from the others, but as soon as I try and have two or more RFID readers running concurrently then only one is recognized in the serial monitor and the others always produce "WARNING: Communication failure, is the MFRC522 properly connected?" I thought it might have been an issue of bad connections so swapped to solder, that didn't help. Tried providing each reader with its own independent 3.3v power supply, that didn't help. When turned on, all of the RFID readers have their power light on, and they never go out, I read that they should be flicking on and off as the controller selects between them, does this provide any insight as to what the problem might be? Thanks for your help strangers :)

[@PlayfulTechnology]

The most common problem is poor connections, so double-check them all. The next is power supply issues, but it sounds like you've already addressed that. The next is caused by capacitance on the SPI bus, which is generally caused by having too long wire runs to the readers. What distance are you running? Can you try making the leads to the readers shorter, and using high quality twisted-pair cables (like the ethernet cables I use)? One other thing you can try when you have problems with a big network is to lower the speed of the SPI interface, to ensure that even the farthest reader has time to respond within the clock cycle. To do this, try adding #define MFRC522_SPICLOCK (100000u) to the very top of your Arduino code. This will initialise the SPI bus at 100kHz, rather than the default 4MHz, and might solve the problem.

[@syedmuhammadumer4693]

thankyou very much for this tutorial. Can you please let me know how can I connect PN-5180 NFC with NodeMCU board?

[@jumbo999614]

Can rdm6300 read 125 mhz 40bit card?

[@PAPARoastDuck]

Hi Alastair. Comparing to RC522 which uses shared reset signal, PN5180 uses unique reset signal and additional unique busy signal. Does that mean if we are to connect 4 PN5180, it would use 7 more GPIO than to connect 4 RC522? I am using a Wemos D1 board which has fewer GPIO, is there a walkaround to use less GPIO? Or a ESP-32 is necessary to have more PN5180 readers. Thanks.

[@geofixated]

Thanks for the video. I purchased the PN5180 and I have it detecting the white card but not with the blue tag. Does anyone know if this is possible and if so how? Thanks.

[@francescoceraso9881]

I had the same problem, PN5180 detect only one white card. U solved?

[@Redbipen]

Holy shit, I finally understand why my mfrc522 captors don't work.

[@gustavohoffmeister5228]

@MyPageMike Caldwell nop

[@SantaDragon]

The sad is, that now after over 18 month the libraries for PN5180 still looks very rare ...

[@roastduck2611]

Thank you! Really helpful information. I have a question, how do you prevent tags being interfered by each other when you try to put an array of PN5180 close to each other?

[@PlayfulTechnology]

If you want to place a lot of RFID readers in close proximity to each other, I'd suggest that the MFRC522 reader might still be the best choice for you. It's inevitable that using a reader with a longer read range like the PN5180 will be more likely to get interference and collision from other nearby tags, so I think you'll want to space them out by at least 30cm or more between each. I am aware that anti-collision systems do exist that enable multiple tags to be simulataneously detected, but I'm not sure if that's supported by any of this hardware.

[@roastduck2611]

Playful Technology thanks for the answer! What about the distance between the Arduino and the module should be like for multiple rfid module? Is there difference between RC522 and PN5180.

[@PlayfulTechnology]

SPI was designed primarily as an interface between components *within* the same device, not *between* devices. So you should place your Arduino close to the readers to keep the SPI wires as short as possible - there are several internet sources that claim 10ft to be the theoretical maximum distance for an SPI interface, but I'd keep it much shorter than this - no more than around 1m.

[@MacGomez]

New subscriber ... Been into locksports for years and I just got into playing around with RFID fobs. I needed one for my hid fob and had no problem. I notice after trying to copy a friend fob I had an issue with his Keri series fob but the 22 key digital smart card rfid reader writer machine with HD display from Amazon wouldn't read or write it. Could you if possible do a video on the best handheld machine for fobs and the type of fob. Can I use a chameleon proxmark on a smart phone or tablet ? Appreciate the channel and info... 😎🤘🏼✌🏼 From NYC-USA🗽🇵🇷

[@yusufsheikh1]

Can RFID Readers read credit card information/credentials?

[@PlayfulTechnology]

No. They can read (unencrypted) data from things like library cards, some travel cards, but they will not read any credentials from a credit card.

[@udik1]

I need cheap rfid tags and handheld reader, for locating inventory items.. any ideas?

[@williamroberts5716]

You don't want to use a barcode label and a scanner? Or is the rfid tag hidden inside?

[@mustafakucukturkmen2363]

I need a long range rfid sensor and also a cheap one thank you for test pn5180 I definetely bought a pn5180 :)

[@dubbeligascheisshausmugg6304]

you can have multiple I2C buses, uses only one additional data line per added reader. less then SPI

[@amircool2529]

They all read and write ???

[@lamboking8able]

I know the mfrc522 writes and the pn5180 has code that writes but still trying to get passed it

[@roastduck2611]

I have encountered some issues where the readers would stop working during an object placement puzzle and I would have to restart Arduino to have it running again. I suspect that the reader would stop working if there is vibration caused by players when they try to place the object with greater force. Is it normal? Maybe I shouldn't fix the reader directly underneath the wooden piece on where the players are placing the object.

[@PlayfulTechnology]

Vibration in itself shouldn't affect the reader unless there's a loose connection somewhere - I'd suggest you check all the cables going to the pins - have you soldered these? Or usong a harness?

[@roastduck2611]

Playful Technology if it is loose connection, it shouldn’t be working again after restart the micro-controller. I soldered a RJ45 jack to the RFID module and connect a cat6 cable to it.

[@illyushen9856]

i want to detect multiple rfids simultaneously which one would you recommend?

[@PlayfulTechnology]

On a single reader? That requires a specialist protocol (normally the RF patterns from multiple tags presented at the same time interfere with each other). With multiple readers, it's trivial - just cycle through them.

[@RajnishDubey1988]

Great tutorial. Thank you

[@ziomalZparafii]

I would guess 15cm is far too long distance for escape room prop. I've seen several RFID riddles and all of them required precision. 15cm is easily exploitable by just moving the card around. Well, that's of course mostly up to a particular riddle to choose the range.

[@PlayfulTechnology]

Generally speaking, the acceptable tolerance of what is regarded as the "correct" position for the tag relative to the sensor should depend on the physical size of the item being placed. If you're placing small items like playing cards or books then I agree 15cm might be considered too generous a margin of error (although also remember that's 15cm straight line-of-sight distance through air - it will diminish once the tag/reader are actually embedded in a prop). However, if you're placing larger artefacts - 60cm high statues on the correct plinths, for example, then 15cm would be perfectly appropriate read range.

[@johannesleno881]
