RFID NFC and Mifare programming – Visual C# (Windows) source code examples Advanced for uFRCoder


A source code example of the application for Mifare card encoding done in Visual C# (Windows) – uFRCoderAdvanced . Advanced application has functions for card sector and block address reading and writing, block value entering and block data value incrementing and decrementing. This software also contains the function for defining the Mifare card keys and key index. Source code of the software is made for use with uFR reader/writer made by D-Logic

This application example is meant to provide the base for further development of the various RFID coding applications and it is considered as a good start for users with complex projects.

  7. Greetings, I have downloaded uFRCoder C++.NET1.0. There are 3 projects: advanced,simple and simplest. I have built the first 2 solutions successfully, however when I run the .exe both from MS VS environment and both from hard disk I get next error: Unable to load DLL 'uFCoder1x.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E), both in release and in debug modes for simple and advanced versions. Please help how to resolve this issue…

  8. Although ultralight has smaller memory capacity, it uses 3DES encryption which is more secure than CRYPTO1 that Mifare Classic 1K uses.

  9. We are using Mifare Classic 1K cards.
    Our Reader does not currently support Mifare ultralight C but we are releasing a new version of the Reader/Writer in the near future that will support ultralight C cards.
