Arduino FDX-B Reader DIY ISO 11784/11785 FDX-B RFID Reader The goal of this project is to create hardware/software capable of reading RFID tags implanted in animals. Only tags that use the FDX-B protocol are supported since they appear to be the most common. Support for HDX protocol based tags would require a significant hardware redesign that I'm unwilling to do at the moment. The EM4100 protocol, that is commonly used by RFID fobs/cards, could be supported with minor changes but that's outside...
