The simplest way to get one is to get a reader/writer from the HID OMNIKEY line. Either the HID OMNIKEY 5321 or 6321 will work and both are fairly cheap at around $50. The model number does not matter very much, contrary to what you may think. I used an HID OMNIKEY 6321 CLi and an HID OMNIKEY 5321 v2 CLi. It is unverified but you may need to use Windows XP in order to use the drivers. I used Windows XP. \n\nTo build the software you want to start off by downloading the [MinGW installer assistant](https://sourceforge.net/projects/mingw/files/Installer/mingw-get-setup.exe/download). Install it and select:\n\n* mingw-developer-toolkit\n* mingw32-gcc-g++\n* msys-base\n\nIt should look something like this:\n\n![mingw](https://cloud.githubusercontent.com/assets/166333/15988849/91724b5c-302d-11e6-994c-33d24211e87e.png)\n\nThen go to `Installation \u003e Apply Changes` on the menu bar to install part of your build environment. \n\nNow go to `C:\\MinGW\\msys\\1.0` and copy everything over to `C:\\MinGW`. \n\n![copying](https://cloud.githubusercontent.com/assets/166333/15988850/98ea89a8-302d-11e6-9620-c5b45406ff87.png)\n\nOpen the `msys.bat` file to get a small shell environment. Clone the provided source code into the home folder, go into the `iclassified` directory, and run `make`.\n\nIf everything runs well you should get `iclass.exe` and `iclassified.o`\n\nAt this point you should plug in your OMNIKEY reader and follow the instructions provided alongside [the drivers](http://www.proxmark.org/files/Various%20Hardware/OMNIKEY%205x21/OMNIKESY5x21_V1_2_0_14.exe) to get the reader setup. \n\nIf all goes well you should be able to execute `iclass.exe read` to read a card and `iclass.exe write` to write to a card.\n\n![writing](https://cloud.githubusercontent.com/assets/166333/15988852/a08fa5d0-302d-11e6-99c5-3b80d4a7d195.png)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcoldheat%2Ficlass","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcoldheat%2Ficlass","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcoldheat%2Ficlass/lists"}
