Pages:  2. Topic: RFID instant cloner dangerous project y? RFID instant cloner dangerous project y? I am interested in showing how useless these are Rfid chips really are.
I have found some information about people building cloners but the design that I have found looks like it could be ported to Arduino. However I can assure you that I'm not searching for such. I may go missing in the night! If anybody is up for working on such a project please let me know. I have seen a video of someone using a Arduino to do magnetic cards using a ipod, but such technology is so generic.
Basically the more heads on board the better! I look forward to hearing from anybody interested. Snipez White hat. Re: RFID instant cloner dangerous project y? I know this thread was posting some time ago but is anyone still interested in this project. Let me know if your interested on working on this project. It shouldn't be that hard, there is already many rfid projects and this would just be incorporating them all into one. I would take a look at these pages. This is becoming more interesting the more i read.
If anyone needs it. RFID tags in a given frequency have many protocols, let it be encryption or something. This is a software issue you can get the data from them but seeing what it says it a different matter. Its like speaking, in the audio range we hear x to x Hz but the language protocol is different That is ss far as my understanding of this goes.
The reason I started back on this topic is to learn how to perform the different modulations needed to emulate the different tags. I sort of understand the different modulation schemes but I don't really yet know how to perform FSK modulation using the Arduino board.
I am hoping to spark conversation so I can work with the group to understand how to perform modulation and better understand the technology as a whole. Sorry, this really smells like BS to me. Why is it that people join the forum with their first goal as being able to record a mag stripe or cloning RFID cards? I can give a lot of credence to obscure goals, but I can't understand someone going to all this trouble just to show how RFID cards can be hacked.
Wanting a better 'understanding of the technology' is a bit more plausible, but it still just doesn't ring true. Provide help if you want. This seems more benign than helping someone make a card skimmer. You can almost justify it in that any good monetary system that uses RFID cards should provide strong encryption to protect against fraud.
Obviously IMO. Wow I thought these forums where to help people learn about Arduino, electronics and programming. I think it is great that when I try to reach out to the forum to learn about something I get smacked down.With this project, you can let people to unlock apartment's door without a key, or modify the code for something else to do. Simply, this project gives you an opportunity to build what you want with this particular RFID reader. I would like to thank dronmarket for sponsoring me about RFID usage on drones.
You define a Master Card which acts as a Programmer then you can able to choose card holders who can able to unlock the door or not. Or you can use both, of course. No Information lost if power lost. You can modify the code and use a Servo motor instead of a relay.
I am new to coding, and know how it is hard to understand whole code as a newbie, I tried to create fully commented code for newbies like me. Maybe its not complete but there are many comments. To keep it simple we are going to use Tag's Unique IDs.
Arduino RC522 RFID Door Unlock
It's simple, a bit secure, but not hacker proof. Master Card can be defined when first use, just scan a card and it will become the Master Card. While holding wipe button, power up your Arduino and wait 10 second without releasing the button, everything will be erased Careful: this process can not be undone.

I suggest build everything on breadboard then tweak for your exact needs, since we don't know how every door unlocks you need to modify the setup.
When your Arduino first run it will flash Blue Led and wait you to scan a card in order to set this card as Master Card. Which will be act as programmer for users' tag. Question 3 days ago. I want to add an card uid in the code, known as 'specialCard', as whenever this card will be scanned the permission will be granted, but this card will not be able to remove and delete from master card.
Reply 4 years ago on Introduction. There are several ways to increase number of tags to be stored. Reply 1 year ago. Hello, and many thanks Omersiar! I have connected FM24wG to my Arduino Leonardo I2C port, and succeeded to make it communicate with Arduino, i was able to write the the card id's in my eeprom. When i try to write after address the IDs are stored starting with address 6 and the first IDs are corrupted.
In my Arduino Leonardo can store up to 60 cards, i do not know why. Can you help me with a solution? This is the code that i adapted to the FM24WG memory.
Usa este deschisa! Nu aveti acces!This is one of my fav topics ever. For this project you must have the understanding of the SPI interface. The card reader and the tags communicate using a The tags that we will use are the ISO A type. We will use the SPI library which is included in the Arduino software. Did you use this instructable in your classroom?

Build a RFID reader/capturer/cloner
You can either use an Arduino Uno or Nano. I use Nano here. MFRC Module 2. Arduino 3. N number of tags 4. Breadboard 5. This is standard SPI connection. Arduino pin no. Once we have the connections up its time to write the code. There are many variations of the code available. Some allow you to dump the UID of the card directly to the serial monitor. The AccessControl example included in the library is a really good code but it is a bit overkill if you are new to the RC so i decided to write a simpler version of the code.
In my version of the code you define the UIDs of the Authorized cards in the code. So once you burn the code into the arduino you cannot add new cards, however from a beginners perspective you can learn a lot from this example. Reply 1 year ago. Question 1 year ago.

Block 0 is the most important block for a card and it's a more efficient approach to write it separately.
If a user happens to move the card and if that happens at the time when the code is trying to write into the block 0, an error at that moment might leave the card useless. Skip to content.

Upon purchasing the module, you will have the RFID reader board, an RFID card and tag and two eight-pin headers: one straight and one bent to 90 degrees. Obviously, you need to solder any one of those pins into the eight holes on the reader board.
The choice as to which header to use depends on your project. The module runs on 3. Fortunately, even though the module is powered through 3. This means, we can just connect the RC module directly to an Arduino like this:.
If you want to use I2C, you need to modify the module to make the chip go to I2C mode. This is discussed in the last part of this article. You can download it in his repository.
The 1 KB of space is divided into 16 sectors. The sectors are further divided into 4 blocks each with 2 bytes of data. You can use the UID of the card to identify it! We can use that memory to write data into the card. To enable I2C, we must cut the connection of the trace on the board to pin 1 on the IC.

RFID is useful to identify people, to make transactions, etc…. You can use an RFID system to open a door. For example, only the person with the right information on his card is allowed to enter. An RFID system uses:. Approximate the RFID card or the keychain to the reader.
Let the reader and the tag closer until all the information is displayed. This is the information that you can read from the card, including the card UID that is highlighted in yellow.
The information is stored in the memory that is divided into segments and blocks as you can see in the previous picture. You have bytes of data storage divided into 16 sectors and each sector is protected by two different keys, A and B. View raw code. In the piece of code above you need to change the if content.

I have all the components needed in this tutorial. Let me implement this. Not bad. Using an Arduino Uno is a little bit overkill.
The Uno and Nano are almost identical when talking about hardware performance. Only real difference is size and nano has 2 extra analog inputs.Today I want to show you how to copy a Mifare classic card with the arduino mega and the rfid-rc module.
Let’s make a simple Arduino RFID reader using the RC522 Module
Note: We have to read a 1K card and keep this in memory. For accessing there exists a lot of arduino libraries in the net. I do not know which library I used exactly, think it was from here. In my example I used an existing Mifare Classic 1K card. This piece of code gives you info about your card. Any new card. The UID number of an new card is normally read only, and programmed by the manufactory of the cards.
In general I am a little bit lazy to give you a big explanation about the code. So this is my first version. Du kommentierst mit Deinem WordPress.
