This security vulnerability is an access control lock trick. The master key is AIR. We can say it stands for Anti Infra-Red, but it really is just air. Guess what, it can open card-key protected doors in many commercial buildings.

Security is important to any business or government organization. Even though an organization has taken all the security measures possible, corporate spies know how to bypass many of them.

The first line of defense for any secure building or office is the door. Many of these are controlled by card-key access controlled locks.

All it takes is one blast of compressed air on the sensor – the door opens and they are in.
