💡 Multiple RFID Readers

[Franzformator]

Feature Description

Multiple RFID Readers for parallel Card and "Figure" function.

What functionality would you like to see in your phoniebox?

Control the Phoniebox by placing a “Figure” on the top or alternatively by placing a card in a separate “Card-Slot”. Both functions should have a separate RFID Reader to ensure a good wireless reception.

How do you envision the feature to work from a users perspective?

It should be possible to control the Phoniebox with RFID Figures and Cards. Set a Figure on one reader would start play. Removing the figure will stop playing. Same function for Cards.
If a figure and a card is on a reader simultaneously the last placed RFID chip should be followed.

Further information that might help

In the moment I’m using a Phoniebox with a Neuftech RFID reader and it only plays if a RFID chip is on the reader (#62)
This feature is elementary for me!
I already have a card slot and a position for figures on my Phoniebox. For now, I have realized this with two RFID coils on one reader. This works under most conditions. But sometimes the RFID chip in a card is to bad, so no card is detected.
It would be nice to get the possibility to connect multiple readers (2+). If it is not possible with the Neuftech reader, maybe it ist possible with RC522

Looking at the reader code, this could be possible.
But I don't know, if it's possible to differentiate 2 reader devices.

Does somebody have two readers and can check how list devices works?

#665 is somehow related although it's a different use case.

I have thought of this feature from a different angle. I have some bluetooth headphones which I pair over RFID (just glued an chip on them).
I think it would be neat, if they had their own spot to hold onto.
According to https://www.raspberrypi.org/forums/viewtopic.php?t=195628, from the hardware side this could be done easily at least for the RC522 I'm using. From what i red there, they just show up at /dev/spidev0.0 and /dev/spidev0.1.

I did not dig into all of this too much though, because my use case just don't justifies the time i could be listening to audiobooks with my little ones otherwise :D.
