When you say BLE Tag, what exactly are you referring to? Could you link me to an example of what you are looking at? I would really appreciate it, as I'm still fairly new to all of this!deepo wrote: ↑Mon Nov 11, 2019 9:40 amThe latter RFID reader is handy, and acts as a USB HID keyboard device, so it should be easy to interface with it, as the ID of the RFID tag read is being sent as keyboard key presses.PiGraham wrote: ↑Mon Nov 11, 2019 8:08 amNothing specific that might suit this application?
There are things like this:

which claim 3 to 5 metres reading range but would that give useful proximity range info under 3m?
It large for handheld use (20cm) and it's £150.
Then there is this one:

Similar price, range 10 to 150 cm which may be more appropriate 120 x 85 x 23 mm
But using RS232 as the first device does is not that hard to do either.
But for scavenger hunt a smart phone with a Bluetooth LE app, and either BLE tags or RPi Zero W's acting as BLE tags can get the OP most of what he needs, except for the feedback part. And it's cheap.
