As my second paper RFID tag, I used a standard potentiometer for being able to adjust read distance of the RFID tag. In order to get a comparable result, this RFID tag has got six windings like the RFID tag with the slider switch.

Unfortunately already a tiny change of the resitance by the potentiometer made the RFID tag inoperable. In order to choose read distance by adjusting the resistance of the circiut, one could try it with a really precise potentiometer in the future.
