FlockFinder FDX Reader – Everything You Need to Know
We built the FlockFinder FDX Reader to work seamlessly with the FlockFinder app. Whether you’re logging treatments, weights, or movements, scanning tags makes everything faster, easier, and more accurate.
🔖 Tag Compatibility
The FlockFinder FDX Reader works with FDX (Full Duplex) EID tags, the most common type used on UK sheep farms.
It will work with any livestock, including sheep, cattle, and goats, as long as they are fitted with FDX tags.
Not sure which tags you use?
Ask your tag supplier. They will confirm whether your tags are FDX or HDX.
⚠️ The FlockFinder reader does not support HDX (Half Duplex) tags.
If you are using HDX tags, see compatible reader options below.
Please note: we cannot guarantee compatibility with Shearwell tags, as they may contain a mix of FDX and HDX chips.
📟 Compatible EID Readers
FlockFinder works with EID stick and panel readers that use Bluetooth Low Energy (BLE).
