The Eye Scan 3000 was one of Gary's inventions. It was used as a security system for the Gadget Room, the centre of Gary's inventions. It was located in the HQ. When you put your eyes on the Eye Scan 3000, it would scan your eyes, but it would only grant access to Gary. However, in Club Penguin: Elite Penguin Force, the player could pass the eye scan by wearing an old pair of Gary's glasses, hinting that there may be a minor defect with the invention.
It was lost in Club Penguin after the PSA HQ was destroyed, but was still in the video games.
