ID Innovations FDX-B Decoder Tool
Decode / encode ISO 11784/11785 FDX-B data for ID-3HP-ISO / ID-3LA-ISO modules
(Secure Cloudflare backend，no data stored, server-side processing only)
Secure cloud processing for ISO 11784/11785 FDX-B decode & encode
Why secure processing?
All decode and encode operations are executed on a protected Cloudflare Worker
API endpoint. No FDX-B frames, country codes, or animal IDs are stored or logged.
All communication is encrypted (HTTPS), and the FDX-B decoding/encoding logic
runs server-side to prevent extraction of proprietary algorithms from the webpage
source.
Input FDX-B data in hexadecimal, one frame per line.
Accepted formats:
• 8-byte ID (16 hex chars), e.g.
• Full frame (26 hex chars), e.g.
Accepted formats:
• 8-byte ID (16 hex chars), e.g.
7D1E45845B780001• Full frame (26 hex chars), e.g.
7D1E45845B7800016BF0000000
Reverse encode (Country + Animal ID → 8-byte hex)
Enter country code (decimal, 0–1023) and animal ID (decimal, 0–274877906943),
then encode to the 8-byte FDX-B block as read from the module.
