HoneyGuardian feeder's RFID tag

For people with experience with RFID tags - I got the HoneyGuardian feeder and the collar is very noisy and shaky. I would like to replace it with a tag that sits on the collar. Does anyone know if these circle RFID tags used by different feeders are interchangeable? Otherwise I'd need to buy new collars from HoneyGuardian (Which are expensive) and break the plastic.

Thanks!
