FDX-A (also known as ISO 11784/5) and FDX-B (also known as ISO 11784/5) are standards for animal identification using radio frequency identification (RFID) technology.

FDX-A operates at a frequency of 134.2 kHz and uses amplitude modulation (AM) to transmit data. It employs a 64-bit code structure and offers a shorter transmission range compared to FDX-B. FDX-A tags typically have a lower memory capacity.

FDX-B also operates at a frequency of 134.2 kHz but uses frequency shift keying (FSK) modulation for data transmission. It employs a 128-bit code structure and provides a longer transmission range compared to FDX-A. FDX-B tags generally have a higher memory capacity.

In terms of compatibility, FDX-B readers can read both FDX-A and FDX-B tags, while FDX-A readers can only read FDX-A tags. This makes FDX-B more versatile and suitable for applications that require compatibility with both FDX-A and FDX-B tags.

Overall, the choice between FDX-A and FDX-B depends on specific application requirements, such as transmission range, memory capacity, and compatibility needs.
