I have a hobby project where I am using UHF tags for counting poultry. The advantage that it gives me is long range (few meters) compared to LF / HF tags. QR code also wouldn't work due to size and distance.

Here's a video.

This looks immensely useful

I've been thinking about ways to count my chickens, making sure they return to the coop and don't get locked out at night. Most of the time all tge birds get in, but occasionally some will dawdle and wind up sitting outside a locked coop door.

You mention this can read for a couple meters. Can it read all the members of a flock, so I could mount a single transmitter in the ceiling if the coop, or is it one at a time, so something that should live above the door

I haven’t played with any stationary antennas but I think it’s possible.

The scanner that is used in the video has configuration for transmit power. At its maximum setting, the range is 15 feet with clear line of sight.

Tags with larger antennas, generally speaking, have longer range but might be too big for younger chickens.

So overall there are a lot of variables.
