    I built a Dalek once using RFID to identify it's master and guests. It had an airsoft cannon to pelt those who didn't "Identify" properly. It used a Raspberry Pi SBC for a main brain, an old Xbox Kinect for it's eyes and ears, and a bunch of micro-controllers for it's peripheral control systems.

    The Dutch people who cracked it actually cracked the public transit card system by overwriting the cards with information about credit for public transit.

      better find where a controller is in your appartment. determine the model, find the manual, reset it to factory defaults, and program your own cards into it. you will end up with a master card which can be used to teach our own cards as regular entry keys. the master card or any teached in regular cards of your landlord will no longer work :) no extra hardware is required besides a couple of extra compatible cards. do not forget to give your new master card to your landlord after you end the rent.

    Thanks for this Julian. This is helping me write a security system for my home where a person would scan an RFID tag to turn off the security features... while it is still all in the future: alarm, facial recognition and video documentation. This is all a hobby at this point, I'm just loving coming up with solutions for problems I want to crack.

  • @GaNgStAlBeRt

    can you actually Write on cards that have a RFID code on it? example: i have a RFID card with a LOGIN NUMBER on it, and you hold it to a machine and then you need to give the password. but the problem is i lost a card which i know the LOGIN NUMBER, but if i wanna get a new card, because i lost my old one, i need to pay 30$...so i wanna know CAN I TAKE A RFID CARD, delete the internal LOGIN NUMBER and PUT a other one on it with this device? thx

      @sunhuatom 8 років тому +3

      that's totally depends. you also need to know where to store your data, and the original data might be encrypted in some form. And for some applications, people dont really write the actual data to the cards. Instead, they only use the tag id(UID), and then link the tag id to the data which has been placed in a more secured database.

    I have one of those inexpensive RC-522 readers. While it reads the card and the keychain thingy that came with the package just fine, I can't really get it to work with other mifare cards (both 1k and 4k cards, and yes I'm sure they're mifare). I've done a lot of experimentation with the library from miguelbalboa, like trying to change the receiver gain registers and the pmos and nmos conductance, but no success yet.
    Perhaps the supporting electronics to connect the RC-522 chip to the reader/writer coil is not up to specification, or perhaps even the RC-522 chip is fake?
    So, I guess you get what you pay for...

  • @GregWoodsLancs
    @GregWoodsLancs 9 років тому +2

    Another really useful video. I too had a play with various cheap RFID, including the RC522. But in the end I settled on a PN532 based card, which is little more expensive, as it has compatibility with a greater range of tags, including NFC. Need more time to play with it though.

  • @vistron888
    @vistron888 8 років тому +1

    I bought a bunch of those blue RFID tags for my alarm system. Originally they were fine but over time they become very weak. You have to touch the alarm receiver in a very exact spot and with the flat side of the tag, otherwise it just won't work. Meanwhile the original tag (grey block) supplied with the alarm works fine. There's something definitely iffy about these blue ones.

    This RC522 module seems to be pretty inconsistent. The more expensive PN532 based modules seem to read all sorts of cards/keychains/stickers just fine, including a card that was originally included in the RC522 package, but which the RC522 itself couldn't read...

  • @micromachine7954
    @micromachine7954 9 років тому +1

    I would love a video that explains how to install one these say in a vehicle. Like the new cars that have the chip in the key. You could set the reader near the keys and only allow the car to start if the chip is in proximity. It sounds like a fun project and it could potentially keep your car a little safer from theft. If you really wanted to get clever you could install it on the power supply for the fuel pump rather then the ignition and place the reader under a cup holder or something so if you were parking your car in a bad area all you have to do is grab the chip outta the cup holder to disable the fuel pump. Just thinking out loud here but I could think of all kinds of fun things to do with rfid if it wasn't so complicated to set-up.

    Uses of RFID ( i dont know how many of are implemented), If you got any ideas feel free to add them as replys.
    1. Package tracking.
    2. Access control.
    3. To store product info in package replacing barcode
    4. Store indoor/outdoor location information such as lobby, stairs, elevator which can be used by blind and other disabled people. Put the cards/tags in location and a reader in cane/wheelchair will read it.
    5. Pet control, get some RFID tags and install RFID reader in kitchen door to keep them away from kitchen, If you dont like pets in kitchen.

      @YeOldeSpellbooke 9 років тому

    • @SproutyPottedPlant
      @SproutyPottedPlant 9 років тому

      Björn Camitz Oyster cards used in London once used the chips mentioned, they had to change them quick I think!! I guess the magic really is in the encryption as you can still buy the chips the new cards use or so I understood although it is hard for me to figure out.

    • @sivalley
      @sivalley 9 років тому

      Knuckles the Echidna The difference has become a sort of segregation of what operating frequency the card uses. 125kHz is used in older RFID/HID cards whereas the 13.56MHz MFC/MIFARE cards are the standard being used for NFC/Google Wallet/Apple Pay/Eurocards. Otherwise they are one and the same; contactless card reading/writing systems.

    Well you can offer services to "disable" RFID" chips on Paranoid American's.
    I got a couple RFid reader/writers because you really need to make sure you have one with the right freq.
    And to disable those implant ones, you can simply spam/write it with random generated numbers, which
    in effect makes them useless..
    Other than that,, not much use..

    Julian, there are hundreds of uses for RFID tags, like for instance, chipping pets, (these are tiny glass capsules which are placed in the neck of a dog or a cat or other animals, and the chip ID can be read and pets are registered on a data base, so when lost and found they can be reunited with their owners, you could use them on cat flaps that reads the chip of your pet and only allows it the access to come into the house and other animals are denied access. You could mark your property, etc etc, I understand that such technology will be implemented on supermarket items such that a reader will read all the items in your trolley and produce a bill that you simply pay and walk out without having to take items out of your trolley on to a supermarket conveyor belt for scanning individual product.

    Perhaps even automatically pick up the phone and dock itself, if you simply put the phone nearby (it'd trigger a search routine). Sortof like a robot comically trying to reattach it's own severed head.
    One cool thing i've seen is people using RFID tags with cutting edge prosthetic arms. They put sticker-tags all around their house and the reader is in the arm, it tells the arm what context it's in. ie: There's a tag on the fridge door which automatically sets the fingers to "open the fridge" mode, one in the bathroom to set it to "hold toothbrush" mode. Handy stuff like that.

    @marinehm 8 років тому +1

    You seem to know quite a bit about RFID and such. At work we have an door with a key pad. I'm pretty sure it reads RFID as well. I think my question is about the frequency of these things. They are not al on the same RF freq. Will these readers be able to get the frequency from the door and be able to write the access pin onto the card? do they make separate cards for each frequency? I don't know enough to even formulate the proper question. I would probably need to have the frequency the door keypads receives before I would go out and purchase a reader/writer, cards/chips?

    @jamesaddyman5506 7 років тому

    spent ages trying to get one of these working in conjunction with a data logging RTC/SD shield on a nano, both communicating over SPI. Turns out it doesn't have tri-state IO. When CS is high (chip disabled), it won't let any other device use the MISO line.
    Took hours to fault find this!! You'd expect an implementation of SPI to be able to share lines. Surely that's the whole point of SPI!
    Can't spare anymore IO on the Nano so going to have to try multiplexing the MISO line with a dedicated chip.

    I found I could make several 'broken' cards usable by writing data to them with my Nokia Lumia and "NFC Interactor" app. Once done, I could read and write them with the RC522

    We have started to use them on our project: Automated Library Management System, wherein we would be using the tags for identifying book, tracking, security checks, smooth technical processing of the books, easy to locate books in library and also certain membership management techniques for library users.

    Funny that they published the paper of de encryption (hack) study done in Holland.
    When everything transportation went digital in Holland, it automatically became a target for hackers.
    It was published in a computer magazine how it was done as well.

    my RFID/NFC project is for Scalextric Digital slot car racing. The Race Management Software needed a faster way to assign a car to a 'lane' and a driver to a lane. With an RFID sticker tag in the inside of every car and hand throttle, and each driver having an RFID card, the race setup process can be made a lot faster. Scalextric... it was never really for kids!

    Hello good afternoon,
    I really need your help, how do I write numbers with decimal places in the memory card. I write whole numbers 1,2,3,4,5 type using mfrc522.MIFARE_Decrement (valueBlockA, value), but record with decimal places no type 1:50, 2:50, 3:50 can not. I am very grateful if you can help me.

    • @sunhuatom
      @sunhuatom 8 років тому

      you can replace the decimal char by some hex number and do the opposite when you read it.

    Where can I download the library files?
    I tried with rfidmaster, it works but i can't find any info on it so i used example sketches and the miguelbalboa/rfid library looks better.
    I also noticed that the module must be powered via 3.3v but it accepts 5V SPI signals and the SS pin is labeled SDA on certain modules because the RC522 chip can be used with an I2C interface.
