The Retinal Simulator BioChip (aka BioChip - Retinal) is a biochip found in The Journeyman Project Turbo! and earlier versions.

This BioChip is used solely for the purpose of deceiving retinal scan activated locks. By projecting an image of a retina with an acceptable vein structure, the BioChip is able to open any door with a retinal scan activated lock.

In Pegasus Prime this is known as the Retinal Biochip but more or less functions the same way.
