I think what he is saying is that the rfid was installed prior to the tint. So if ever he was to sell the car and remove the rfid, he has to cut the tint first to remove the rfid beneath it.
I had 3 vehicles in one account. when we sold one I just surrendered the card to the autosweep personnel and filled out a short form removing the sold vehicle from my account. easy enough.
in hindsight dapat pala tinanggal ko nadin yun rfid sticker bago nabenta
