The disc is otherwise printed like a “normal” Bluray, but there is this metallic quadruple ring on top. The image is from the “proof” of a scene release, so it might have something to do with being an early release.
RFID type circuit. Would need to calculate the antennas length to find the operation frequency. The barbell shaped thing at the top is just a bridge, the thing on the right is the circuit.
It looks like an NFC antenna. But I can’t explain why would one be on a disc.
Does it provide some additional data to a player? Or helps the publisher track it somehow?Unfortunately all I have is this image and an ISO of the disc 🤷
My library does this for checkouts, and to make sure you arnt taking an un-checked out movie
Some kind of anti-removal or tracking measure, except applied directly to the disc instead of the sleeve or case?
It could be an alarm badge like in stores but to set off alarms if the disc passes the doors of the movie studio screening facilities.
