PADD

A PADD, short for Personal Access Display Device, was a handheld computer interface. PADDs were used by multiple alien cultures and societies, including the United Federation of Planets, and Romulans.

In 2339, an away team from the USS Tempest (NCC-10535) discovered a Romulan PADD in a hidden outpost abandoned by the Romulans, which had escaped destruction. This PADD provided valuable information on the Romulans' purpose and own efforts investigating the same temporal anomalies the Tempest had come to investigate.
