The Wrist Computer improved upon the 2-Way Wrist TV by adding a variety of additional functions, including a long-range wireless datalink that allowed the wearer to have easy access to various databases for fingerprints, license plates, firearms registries, etc. Furthermore, the device had a lie detector function and a wired stylus-like probe for on-scene chemical analysis of evidence. The Wrist Computer was later upgraded to the Wrist Geenee.
