Description from @Toqqi:
I used the signal python library to detect when a RC522 RFID reader stops reading in a card ID for one second.
This then triggers the playerpauseforce action in playout_controls.sh.

I then configured the second swipe action to be "resume playback" to achieve the play/pause effect when moving an RFID card to/from the reader.
