The Wristlink is a miniature communication device that the wearer can use to visually or auditorily connect with other members of the Public Safety Bureau in real time. It is especially useful in the field, when technical expertise is needed as the Inspectors can contact the Analysts housed at headquarters and their powerful computers. In Sinners of the System Case.1 - Crime and Punishment, Akane Tsunemori is seen wearing a wristlink on both wrists in order to speak to more than one person at a time. The PSB uses special holo-devices called Wristlinks with multiple functions: phone calling and receiving, projecting a hologram keyboard, sending information and mail, connecting to the department's system, controlling drones, dealing with fundamental analysis on case evidence, storing information, etc. The wristlinks for Enforcers are more difficult to take off to prevent them from running away.
