This system can tell if workers are lying by looking at their eyes

The system revolves around an SMI-made camera that monitors pupil dilation as well as the positions of the eyes and head. If you look shifty when answering questions, your supervisors will likely know within minutes. It's not a perfect system; Converus claims 85 percent accuracy, which could allow for occasional false positives.

Imagine the future Google glasses (or contact lenses) that constantly run in the background analyzing someone's face, eyes, and body language and can tell you instantly if someone is being untruthful.  Even with only 85% accuracy that is crazy cool (and scary).  I think a lot of the imaginary sci-fi stuff we see in movies is just waiting for chips and batteries to get small enough.
