I also liked the joke!

i love the jokes in every episode , its like searching for easter-eggs ...

Went right over my head... I heard him say it, but never twigged to it being a joke. I was thinking there is no S there.

I bet the S-RFID cards have either DES or AES cryptosystem on board possibly even both.

@@DAVIDGREGORYKERR DES??? lol. Not much better than double ROT13

You are welcome. This is one intention of this channel.

Thank you!

The Americans could probably say the same thing if you look at Los Alamos or Saturn V. Some leading names there also sounded quite German ;-)

You will get most probably two of them: One about cloning and one for UHF tags.

I think the wallets have a similar foil built in as I showed. So I would assume the effect is the same.

You are welcome!

Sounds like a useful application. And when your kids grow up, you can log, when they came home ;-)

So the next part could be interesting for you ;-)

You are welcome. It is easy to get the information on the internet if you ask the right questions ;-)

You are welcome!

So I have to assume your shed is finished by now?

Let's say it's the never ending story. Well, it's almost ready. I'm now looking into finishing the floor. I haven't made a final decision, but I would like to pour an epoxy floor. After that is finished, I'll bring in the furniture. Smaller details are to be carried out in the next month, but at the same time I'll start using the shed. Here's a picture of the work in progress.... photos.app.goo.gl/udfSVFbrR6uUyUr39

Looks nice!

Welcome aboard the channel!

Thank you!

It will take a while :-(

Andreas Spiess no problem. I am sure it is worth waiting for:-)

Have fun!

It should already be there

Yikes. I did not realize it was a year old video. If it was the attempt with the yaggi antenna then I have seen it. A newbie here and really enjoy your content. Great production

You are welcome!

Hopefully. The protocol is standardized on 125kHz. On 13 MHz it is a little trickier...

Thank you!

Thank you for your feedback. So you found a good way to live with this insecure technology.

As long as you are using the tags in a predictable environment we can say it's fairly secure. Anything other than that, you need to use your phone's NFC capabilities. We also collect the wristbands for reuse when the customer is leaving. Trying to be a little greener here and there :)

Alfredo Rivera As I said in my comment above...when it comes to payments, I have the user enter a 4 digit (or more) pin and then scan their tag. This makes it something they know and something they have. That increases the security in the right environments.

Dan Hoover We have made runs of this mode, but given that we are focused in festivals and concerts is a little troublesome. We are now trying scanning and then presenting two colors in the screen of the terminal and having the customer choose their color to confirm the transaction.

The research was also interesting for me. Especially the history...

Funny how we hated history in school, but now its very good! :D

You're welcome!

Never heard of them. But I will order a few to check them out... Thanks for the tip.

I assume you are the expert (not clear in your post). I am certainly not an expert as I did not know anything about RFID one week ago ;-) From what I read, for a long time, you get much better cards. But the old ones are still used, especially by Makers. Maybe also because they are easy to understand and use. The next generations will no more be very interesting for a video. No hacking possible :-(

@@AndreasSpiess I have some experience with this technology. :-) My point is that you have done VERY well understanding how the technology works and its use today. Your ATC analogy is a good one. A modern super fast equivalent is smartphones with NFC that combines connectivity, identification, authentication and payload. We may see RFID card / fob readers adapted to interface to NFC devices using a hybrid Secured Element Identifier (SEID) Chipset. However, it currently uses only the lower frequency band in the ISM space. Years ago, I developed a early Android App using NFC that added an additional security layer, by including biometric scan as part of a two step authorization process on the smartphone device, which, once authenticated, allows the NFC Chipset to send an authentication code to an RFID reader. If the phone was lost or stolen, it would not work unless the finger was... The goal was to reduce the number of pass cards a user might be required to have access multiple platforms and systems while maintaining two step security protocol. This is particularly true of loyalty rewards cards when they were first introduced. Now barcodes are used to easily display on any smartphone screen eliminating any demand. We will probably see in most markets, a continuous decline of legacy RFID card readers with updated scanners taking their place except where extreme environmental conditions and long connectivity distances exist. Real-time Encryption using one time transaction codes are becoming highly desirable. Blockchain has been touted as one approach which has significant issues including payload size along with latency issues. RFID still has life and is accepted in low security environments and has potential to be significantly upgraded. For tracking and monitoring applications, it remains an excellent low cost solution. As I have mentioned before, the potential in the agricultural and forestry sector is an interesting opportunity. I know you have asked for some additional information, which I will get you later this week. The problem is that some of the documents are in PDF files only and links are not easily posted.

Fortunately these modules do not cost an arm and a leg ;-)

Thank you for your feedback. Maybe you check now once if you can read it. But pay attention with the magnetic strip and 125 kHz. Maybe it is erased afterward...

Andreas Spiess thanks for your warning, but fortunately the magnetic strip works correctly: the entrance to the building is rfid but the entry and exit stamping is magnetic stripe. the anti-theft-car reader is very small 2-3 cm in height by 8-10 in width ... I do not know if there is an RFid HF coil. bye

Thank you for your support! Much appreciated.

You are welcome!

:-)

Welcome aboard the channel!

You are welcome!

And I learned to fly in Florida. And we discovered that my transponder did not work when I wanted to land in Palm Springs with a nearly empty tank. I never forget that.

Thank you!

So you probably also have a few grey hairs ;-) It is sometimes astonishing what was achieved in the old days with only a few technical possibilities. E.g. the flight to the moon and back...

Andreas Spiess: fizeau-foucault apparatus is a prime example of that, with just clockwork and mirrors, measure the speed of light! In 1845 with in 5%. Videos like yours and other are showing off the "clockwork an mirrors" of the future. Thank you.

In open land, LoRa might be another possibility. I know of a guy who can predict when cows can become pregnant by checking their movement and send it via LoRa. I do not know if it is directly sent to the bull ;-)

The sleeve part was too sexy for UKposts without being age-restricted.

Obviously a production error. Sorry for that!

Vonries: Andreas realized that he had showed us his bank account number :-)))

And you even could implant an RFID chip in your hand. Then you for sure would never forget it ;-)

I did not check the modulation. They also use PSK.

@@AndreasSpiess Pulse shift key very cool indeed.

You are right. Some of the modern chips support anti-collision. But the one I used not. If you combine only one which does not support it, your spectrum is "closed" as it always transmits.

1. Wiegand readers have two data lines (D0 and D1) 2. The buzzer and the LED was controlled by the reader itself 3. You cannot write cards with this device (at least I do not know how)

Thank you!

Andreas Spiess I’m so tempted to buy the Proxmark3 module🤔 it looks a lovely piece of kit. What do I do? Oh these conundrums confuse me 😀🏴󠁧󠁢󠁥󠁮󠁧󠁿

Unfortunately, it is also made for the "not so lovely" people ;-)

I will try. But I think UHF will win.

I think so, if the module offers RS232.

That is for sure a much better security than the card alone!

Glad you enjoyed it!

Too long. Because I had to learn everything about RFID and also a little about the Proxmark3. The production itself takes about 10 hours for a 15 minutes video

So far I have no Smartphone with NFC, so I cannot check. But they seem to be on 13 MHz, like the other Tags. But they are more secure.

I do no more remember. Maybe it has a built-in voltage regulator

Thanks for the info. Do you have links to such readers?

Hmm, actually we build our own readers. Looks like they are not so popular so Chinese folks didn't really built any. I'll try to look something u for you. There are definitely some evaluation boards on farnell, etc.

What?! 90 cm?! I'll have to check it out if it isn't too expensive! Even the PN532 has a range of maximum 10 cm. Also, 633 what? I've tried RC633 and MFRC633, but neither give relevant results on Google.

So I have some real pilots amongst my viewers ;-) Unfortunately I learned to fly in a hijacker‘s flight school in Venice, Florida:-(

You are welcome! This channel is not intended for beginners, or only for ambitious beginners.

I have a colleague which has an escape room and he also uses a few of them. Interesting! I only recently heard of these escape rooms.

First time I was in one, I recognized all the parts from maker sites/videos and my own collection and tried to figure out how everything works. Must be a nice project if you have the space.

Justin Richards scape rooms? Like a mans cave?

Andreas Spiess escape rooms, like the panic rooms you see in the movies?

Like this one: www.roomescape.ch/?lang=en (built by my friend)

Thank you!

They use UHF tags and quite strong transmitters. I have UHF tags and a reader here to experiment and will cover it in a video. But I do not have an (expensive) high power device.

Thankfully, your key is encrypted. Otherwise, everybody could enter you home ;-)

@@AndreasSpiess haha yes i figured. But I still want to duplicate the key. Do you have any suggestions?

10:55: A production error. Sorry for that!

its a deleted scene , we got for free

That is a good idea. Also I’d be interested in trying to make an alarm card for my wallet which would be triggered by someone attempting a scam scan.

@@CTCTraining1 i think it would be a device rather than a card but good idea

Thank you!

Unfortunately I cannot do remote debugging :-(

Wasn't so much hoping for debugging advice, but how you wired yours when you were testing. But thank you for replying.

This is longtime ago and I am na old man :-(

Not so old I think :) But I certainly understand and respect your response. I continue to look forward to your informative videos.

Maybe with a special antenna design. And maybe you also have to amplify the signal of the transmitter to provide enough energy to the chip in the card.

You should not rig the pokertable...

Thank you!

Are you sure you do not read the bytes described here: www.priority1design.com.au/em4100_protocol.html ?

I have actually written a little "essay" about my findings...sites.google.com/view/experiences-with-em-rfid-tags/home

I saw that the Mifare can have 7 byte UID. But all the cards I purchased were only 4 bytes. Where did you get the 7 byte ones? In the next video I will clone both types of cards.

@@AndreasSpiess eg UL, DesFire or Plus. Some new classic have 7 bytes too. Probably hour UL card have 7bytes, but configuration od reader returns only 4? Another question - MF have strong coding of transmision. I You like, we can talk more about RFID - please priv message or email

I did not want to go more in the details of RFID since these cards are not commonly used by Makers and I do not want to become a specialist. I wanted to concentrate on the ones still widely used and the basic understanding.

Unfortunately, I only have an old Android phone without NFC chip. So somebody else has to do that video :-(

I do not have knowledge about these topics :-(

I do not know how the cards in shops work. I only read that they have one bit which is flipped when you pay. Maybe the scanners are very primitive? Concerning Robo Tank. Good idea!

I answer all comments. But I have no advice here

And what about you combine a Hitag and a normal one? It seems both have to support anti collision to work?

www.nxp.com/products/identification-and-security/smart-label-and-tag-ics/hitag:MC_42027

Generaly EM4xxx does not support anti collision but Hitag 1 and S yes. Anyway they should not work sticked together (EM + Hitag)

For security in Mifare I suggest to use Desfire. Also Plus are quite safe - Debit card are Mifare Plus. Cheapest way is to take Mifare classic, use own authentication keys combined with data ciphering (f.e. AES).

NFC: 13.56 Mhz

I hope it is not necessary to protect it as it should be safe.

Radio waves in general do not easily travel through metal.

I do not know :-(

Car RFIDs work differently and I do not know how.

So enjoy your breakfast now!

The two "professional" readers I have do not provide information about their capabilities. The two boards should be able to write, too. But I did not investigate. I assume you also need software to do it.

Well the software I can write for myself, as long as there is some kind of documentation on how these devices should work.

I talked and said, that it will be covered in a later video.

Similar. It is only a simple example without some of the original features

I do not think so. I plan to read the Dishka‘s chip, but with the proxmark3

hmm. Ok, I couldn't find a reasonably cheap reader module on AliExpress for 134.2 KHz. To build something like this would be super cool - www.surepetcare.com/en-gb/pet-doors/microchip-cat-flap-connect

As the animal ID system is standarized, check out products for ISO11785 or ISO 14223

Runners are usually tracked with UHF RFIDs. There is also a video about that on this channel.

Andreas Spiess Thank you. I have a Concept for a Next level Event, that will benifit from various RDIF systems. #FLUXXIX #2020Vision

I do not know as I have no transmitter for this frequency, and if I had one, it would probably not appear on UKposts as it would be highly illegal ;-)

You say transmitter (sounds like HV) and I meant an industrial induction heater (more current) for metal parts/heat treatment. Would you say, it only works ("kill") with higher voltages, and not with big current? Would (theoretically) a induction charger (5W) be able to kill, the card, or are the frequencies legally attributed for these chargers.

You mentioned "the right frequency" in your post. This triggered my response.

A few seconds in a microwave would probably do the trick... ;o)

This means that you have to be able to read over distance and the tags need to have a "collision detection" mechanism. AFAIK this is only possible with UHF tags.

I did not investigate long and used a coil.

I do not see a feedback nor a question

Andreas Spiess well, the feedback is that the reader works crappy for me on one frequency. This might interest people who plan to order this part. Question is whether somebody can confirm such behavior.

Bow I got it. Thanks for the clarification!

Andreas Spiess 👍

The link is in the video description. But I do not think it is a 4.0

I am not sure what driver you need for that. The „coil“ is quite large and the distances, too.

i once mounted a large antenna behind the door, it was only powerfull an read only in the corner of the antenna. maybe something for a next video? -- see here, to see more antennas and the large one. interesstingly they build it with ribbon cable for hardisks... www.rss-systems.de/shop/rfid-systeme/rfid-systeme-125khz/antennen-lf/ulr190-u-long-range-190x85cm.php

спасибо

:)

If I remember right it just outputs the number on Serial. There you can read it. No big deal.

Andreas Spiess Yes, thanks. I was a bit confused with the LED and buzzer pins. The device is not widely used nor documented but I found this info which looks helpful at smartpoker dot jimdo.

I will try that in the next video.

Unfortunately, I cannot do remote debugging.

@@AndreasSpiess If i power chinees arduino with usb can it give me 200 milliamper from5 volt pin or less

You are welcome!

Thank you!

@@AndreasSpiess welcome sir

They seem to be on 134 kHz. I will try it for the next video as we have Dishka with a chip...

The chip is usually injected into the skin near the left shoulder. I guess any stationary scanner would have to have some range. Or the animal has to be trained to rub against it until the device beeps. Different solution would be a down-powered BLE fob in the collar.

Just wait until cats learn to change their UID so they can get double the food.

I have the AlieExpress reader and keyfobs installed on the doorbell system of the main access door of a commercial building. This is not very safe, but the door is secured by a shutter at night anyway. I'm planning on using the same thing on the toilets because tenants and their visitors often make a very big mess there. I'll give every tenant their own key to the toilet that they can share with their visitors. I suspect that then their visitors will be more careful because people are more responsible when they're not anonymous.

+ Ruben: Concerning responsibility: You are right. But tracking people like that would probably be illegal in many countries ;-)

I only made a video about animal tags on 134.2KHz.

We will (hopefully) see this topic in the next video (crack hotel card)

When will be next video ?

I do not know yet.

???

Das kommt auf die Anwendung an (was der Reader ausliest). Ich denke, für normale Anwendungen ist das nicht möglich.

@@AndreasSpiess Danke für die schnelle Antwort.....👍

I do not think so :-( RFIDs in keys are only short-range

@@AndreasSpiess yeah, thanks for the response, figured that out, there's chip in my second car key, ATA5702, which sends out a continuous signal, and I guess, at a certain distance, my car recognizes it, Now, all I need to build is a way to detect a rf frequency if that's nearby. The frequency I could figure out with my alternate key... Any suggestions on this sir, any comment would be a great value...

Thank you for your feedback! :-)

Usually not because they are encrypted.

I do not think such specialized topics would fit this channel. I just wanted to show the „state of the art“. That people know what they everyday use.

Andreas Spiess Oh, I like your video, it explains a lot. Am merely expressing that we live in the stone-age of digital security.

Exactly!
