EMI shielding sheets films rfid absorber
rongly reflective to electromagnetic waves, so it will be accompanied by the signal weakening, the card distance will become closer, serious interference will appear card failure phenomenon. The current common solution is to put a layer of wave-absorbing material on the back of the electronic label.
