Hi.
I am looking for a solution that will help to track unit presence in the store. Basically small tag that could be attached to the unit and the reader that can be placed somewhere in the store that will see if tag in or our range.
-tag should stay alive for at least a year
-ideally if range will be 30-50 ft
-reader should support up to 100 tags at the same time (can be less if there any other options)
From what I see there could be different protocols solutions starting from bluetooth/zigbee/lora
Does anyone have any experience with something similar?
Thank you.
