"PADD" is an acronym for Personal Access Display
Device, a hand-held computer interface, used as early
as the 22nd century and well into the 24th century.
Consisting of a large touchscreen display and minimalistic
manual interface or control panel, the typical PADD is
used for a variety of functions including logging manifests,
compiling duty rosters or diagnostic reports, entering personal
data, and/or accessing library computer systems. These are
fan made props, and from Roddenberry Productions.
