Created specifically for the unique demands of the prison services, Tephra’s Movements solution provides high level security and safety whilst supporting a less institutional living environment.

Tephra Movements is a multimode access device developed to accurately confirm the identity and control the movement of prisoners within the facilities. For increased security, two-factor authentication is used to verify identities applying a combination of biometric, RFID and / or PIN, to create a strong multifactor authentication system.

By enabling choice and giving prisoners greater controlled physical movement holds the potential for prisoners to adopt positive behavioural traits which provides them with a greater sense of well-being and independence.


Monitoring prisoner movement is a constant challenge. Generally, prison environments are designed to limit prisoners’ ability to move around and this can reinforce feelings of helplessness, frustration, and despair.

Significant effort and attention by prison staff is required to control internal prisoner movement including manually issuing paper passes, accurately performing visual identifications, delivering appropriate supervision and physically recording when prisoners have left one area and entered another.

Giving prisoners greater controlled physical movement and responsibility provides opportunities for more meaningful interaction with staff therefore facilitating positive behaviour change.
