RC (Region Code): A digital rights management technique designed to allow film studios to control aspects of a release, including content, release date, and price, according to the region. Almost all Blu-ray discs are encoded with a region code restricting the area of the world in which they can be played.

Blu-ray has 3 regions as A, B, and C:
A: North America, Central America, South America, Korea, Japan, Southeast Asia
B: Europe, Middle East, Africa, Australia, New Zealand
C: Russia, India, China, Rest of World

Passkey for Blu-ray can remove Blu-ray Region Code to let you view Blu-ray with no region limit. It's very simple to operate.

Just run Passkey for Blu-ray, insert your source BD, and you'll see that Passkey is opening it. During the process, RC and other protections are being removed.

Seconds later, this window will disappear and everything will be done. You can check back in the Info page of Passkey to see that RC has been removed. OK, that's all there is to it.
