"'''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]].
PADDs were used by such [[space]]-faring organizations as [[Earth Starfleet]] and the later [[Federation Starfleet]], as well as by the [[Andorian Imperial Guard]], [[Bajoran Militia]], [[Cardassian Union]], [[Klingon Empire]], [[Romulan Star Empire]], and [[Vulcan High Command]]. They were common to cultures even as distant as the [[Delta Quadrant]].
==General Specifications==
[[Image:Insidepadd.jpg|thumb|Inside a Starfleet PADD]]
Consisting of a large touchscreen display and minimalistic manual interface or control panel (generally only one or two buttons), 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.
Varying in size, shape and specification, PADDs are often distinguished by the species of their manufacturer or user, [[Earth]] and [[United Federation of Planets|Federation]] Starfleet PADDs generally flat and rectangular in shape, [[Klingon]] and [[Cardassian]] PADDs often more angular.
:''The internal circuitry of the Starfleet issue PADD circa [[2360s]] was revealed only once, in the [[TNG]] episode {{e|A Fistful of Datas}}. While the ''[[Star Trek: Deep Space Nine Technical Manual]]'' indicated [[isolinear]] internal components, the aforementioned episode portrayed a PADD utilizing printed circuit boards just like present-day computers, and only partially made of isolinear circuits''
:''The ''[[Star Trek: The Next Generation Technical Manual]]'' states that Starfleet PADDs are powered by [[krellide power cell|sarium krellide power cells]], and have an outer casing of [[boronite]] whisker epoxy, which would allow the PADD to sustain a 35-meter drop without damage.''
==Earth Starfleet==
[[Image:PADD 2150s.jpg|thumb|A typical PADD, [[2151]]]]
Standard issue during the [[22nd century]], PADDs utilized by Earth Starfleet were rectangular in shape, dominated by a large display screen taking up much of the surface area of the device. Small buttons were located just below the screen, most often grouped in two, at the lower right-hand side of the interface. Varying control button arrangements were also in use. ({{ENT|Vox Sola|Dead Stop}})
These PADDs were often used to display schematics, or [[subspace communications|subspace transmissions]] and were capable of wireless computer networking as well as playing movies, recording [[log]]s and audio playback. ({{ENT|Breaking the Ice|Dawn|Twilight}})
At some point between [[2144]] and [[2154]], [[Arik Soong]] was able to open all the locks in the [[San Francisco]] prison he was being held at using just a PADD. After this incident, he was only allowed to use paper when sketching and writing his ideas. ({{ENT|Borderland}})
While under the effects of [[trellium-D]] in [[2154]], [[T'Pol]] shattered a PADD on [[Captain]] [[Jonathan Archer|Archer's]] desk. ({{ENT|Damage}})
:''The prop used throughout the run of ''[[Star Trek: Enterprise|Enterprise]]'' was not referred to by name until the [[ENT Season 3|third season]] episode {{e|Zero Hour}}. It was created from a Cabin Light Box (Cabin Pocket-Vue CL-5000P Pocket Light Box), a device used to view transparencies or undeveloped film, augmented with 3M Rubber "Bumpons" for buttons, and a rubber "bumper" for what has been presumed to be a camera. A tutorial for a homemade version can be found online.'' [http://www.mattmunson.com/props/star_trek/enterprise_padd_tutorial/index.html]
:''One of these PADDs is currently located in the ''[[Star Trek: The Experience]]'' museum in Las Vegas, Nevada, while another traveled with the ''[[Star Trek: The Adventure]]'' exhibit.''
==Federation Starfleet==
[[Image:TOS PADD 1.jpg|thumb|A Federation PADD, [[2260s]]]]
[[Image:PADD 2370s.jpg|thumb|A Federation PADD, [[2373]]]]
[[Image:Hansens final log.jpg|thumb|A horizontally held PADD]]
One of the most often used devices employed by personnel serving in the Federation Starfleet, PADDs were common aboard Federation [[starship]]s, [[space station]]s, and [[planet]]ary facilities during the [[23rd century|23rd]] and [[24th century|24th centuries]].
First appearing as late as [[2266]] aboard such starship types as the {{ShipClass|Constitution}} vessel, PADDs of the [[2260s]] were large, wedge-shaped devices, operated almost exclusively through the use of a stylus. These data PADDs were often carried by [[yeoman|yeomen]] aboard starships, but appeared in other locations including Starfleet's [[Starbase 11]]. ({{TOS|The Man Trap|The Menagerie, Part I|The Menagerie, Part II}}; {{DS9|Trials and Tribble-ations}})
:''While it has never been explicitly referred to as a PADD in any of the ''[[Star Trek]]'' series or [[Star Trek films|films]], the ''[[Star Trek Encyclopedia]]'' uses this device, as well as the clear, PADD-like device carried by [[Pavel Chekov|Chekov]] in {{film|6}} to illustrate its small section on PADDs. Before the first appearance of the [[TOS]] PADD in the first aired episode, a clipboard was used for the same task in {{e|The Cage}}. Several [[Star Trek: The Original Series (Pocket)|TOS novels]] use the term "data slate".''
By [[2364]], PADDs had taken on a smaller profile and, while some models would include one, the stylus was replaced by simple, touch-sensitive controls, generally located beneath a small, square-shaped display screen. Generally small and light-weight, the PADDs of the [[2360s]] and [[2370s]] were basically rectangular in shape, but varied in size, proportion, and even color – ranging from gray and muted blue colors, to red. Some PADDs, like the one used by [[Doctor|Dr.]] [[Lewis Zimmerman]] aboard [[Jupiter Station]] in [[2376]], were translucent. ({{TNG|Encounter at Farpoint}}; {{DS9|Emissary}}; {{VOY|Caretaker|Life Line}}, et al.)
While the common function of these Federation PADDs was most often straight forward data entry or data retrieval, some PADDs were capable of more artistic tasks. Some PADDs, often larger in size than most of their counterparts, were used to draw up schematics or to create composite images or artwork. PADDs were also capable of predictive text functions, allowing users to enter a small amount of data to achieve full words or even sentences. ({{DS9|Babel|The House of Quark|Image in the Sand}})
:''PADDs as they were seen in the spin-off series were designed during the pre-production stage of ''[[Star Trek: The Next Generation]]'', at least in part by [[Rick Sternbach]]. An early drawing (bearing a strong resemblance to the prop used well into ''[[Star Trek: Voyager]]'') can be seen in the book, ''[[Star Trek: The Next Generation - The Continuing Mission]]'', dated {{d|17|March|1987}}.
:''Such 24th century PADDs first appeared in the episode {{e|Lonely Among Us}}, where they are still called ''P.A.D.D.'' in the script. The device was also called P.A.D.D. in the script of {{e|Too Short a Season}}, Beginning with {{e|Loud As A Whisper}}, they were called PADDs or padds in the scripts. They were first mentioned by name in the episode {{e|A Fistful of Datas}}.
Not long after their debut in [[TNG]], PADDs became a real-life technology with the introduction of the Apple Newton; Palm Pilots being a similar device common in the world of the present.''
:''Unlike their real world counterparts, most PADDs on [[TNG]], [[DS9]] and ''Voyager'' were nonfunctional, rarely even incorporating lighted display screens, but rather printed "[[okudagram]]s". This might suggest that some PADDs incorporate [[Wikipedia:electronic paper|electronic paper]] technology. Lighted PADDs did eventually make their way to screens for {{film|9}}, with custom and store-bought devices like the Cabin Light Box, being used through {{film|8}} and into ''Enterprise''.''
:''According to frequent background performer [[Guy Vardaman]], [[TNG]] extras often referred to the PADD props they carried down [[corridor]]s as "hall passes".''

==Andorian Imperial Guard==
[[Image:Andorian PADD.jpg|thumb|An Andorian PADD, [[2154]]]]
Roughly the same size as their Earth Starfleet counterparts, PADDs used by officers in the service of the [[Andorian Imperial Guard]] were rectangular in shape, highlighted by several square-shaped pieces at the sides and top which itself was rounded.
Unlike the Starfleet version, no obvious buttons or control panels were visible on the device, suggesting that the large, center-mounted display screen was touch-sensitive. ({{ENT|United}})
:''Likely a redress of an existing PADD from ''Enterprise'', the Andorian PADD from {{e|United}} was a functional light box, likely of the same make as those used to construct the Starfleet versions.''

==Bajoran Militia==
[[Image:Bajoran PADD.jpg|thumb|A Bajoran PADD, [[2375]]]]
In use during the 24th century aboard [[Bajoran]] spacecraft and stations (including [[New Bajor]] and starbase [[Deep Space 9]]), Bajoran PADDs were small, roughly oval-shaped devices, nearly the same size as (though slimmer than) the small Federation PADD variant.
Capable of the same general function as their alien counterparts, Bajoran PADDs could be used to download information from primary computer sources, including text documents as large as [[novel]]s. They were also able to display information in Bajoran as well as other languages. ({{DS9|Emissary|The Jem'Hadar|Shadows and Symbols}})
<br clear=all>
==Cardassian Union==
[[Image:Cardassian PADD.jpg|thumb|A Cardassian PADD, [[2369]]]]
Used by both civilians and military personnel, the typical PADD used throughout the [[Cardassian Union]] could be found aboard {{ShipClass|Galor}} warships and on [[Cardassia Prime]] itself.
Consisting of a brown and gold-colored unit, the Cardassian PADD was angular and irregularly shaped, featuring an oval-shaped display screen and a number of trapezoidal and irregularly shaped buttons.
The Cardassian PADD was capable of a variety of functions, from displaying visual recordings to operating door mechanisms. ({{TNG|Chain of Command, Part II}}; {{DS9|Emissary|Second Skin}})
:''According to an in-depth article on PADDs in ''[[Star Trek: The Magazine]]'', several of the distinctly alien Cardassian PADDs were repainted Federation standard colors and used in the [[Star Trek films|movie]] {{film|8}}.
:''The Cardassian PADD was also fitted with a larger, lit display screen for use as scanners in ''Enterprise'', as an [[Earth]] device in {{e|Regeneration}} and [[Klingon]] device in {{e|Bounty}}.''
<br clear=all>
==Ferengi Alliance==
[[Image:Ferengi PADD.jpg|thumb|A common Ferengi PADD, [[2374]]]]
[[Image:Ferengi auction PADD.jpg|thumb|A PADD used at auction]]
A mainstay in business dealings involving [[Ferengi]] in and outside of the [[Ferengi Alliance]], Ferengi PADDs were often elongated-hexagonally-shaped units. Muted gold in color, these PADDs featured a number of button controls and a hexagon-shaped viewscreen often displaying the familiar circular Ferengi interface layout.
Capable of cataloging inventory, inputting vouchers, or drawing up business plans, Ferengi PADDs were most often geared toward business and profit. Chief amongst their capabilities was currency transfer, allowing transactions to take place with simple thumb print verification. These PADDs were utilized by [[Ferengi Commerce Authority]] [[liquidator]]s and could be found at the [[Tower of Commerce]] on [[Ferenginar]], as well as aboard Ferengi vessels like [[Nunk's Marauder]] and at [[Quark's]] on Deep Space 9. ({{TNG|Firstborn}}; {{DS9|The Wire|Family Business|The Begotten|Profit and Lace}}; {{VOY|Inside Man}})
Other Ferengi PADD variants included a flat, black and green device with an angular display screen. This PADD variant could be used to view [[auction]] catalogs. ({{DS9|In the Cards}})
:''The Ferengi PADD seen throughout [[DS9]] was reused in the ''Enterprise'' episode {{e|Acquisition}} as a Ferengi [[scanner]], revamped with a lighted display screen.''

==Klingon Empire==
[[Image:Klingon PADD small variant.jpg|thumb|A small Klingon PADD in [[2373]]]]
[[Image:Klingon PADD.jpg|thumb|A larger Klingon PADD variant]]
At least two models of data PADDs were used by warriors in the service of the [[Klingon Defense Force]] during the 24th century.
Both harshly angular compared to their Federation counterparts, Klingon PADDs came in hand-held and larger, landscape-style varieties. Both displaying information in [[Klingonese]], these PADDs could be found in the chambers of the [[Klingon High Council]] on [[Qo'noS]] as well as aboard Klingon vessels such as the [[IKS Rotarran|IKS ''Rotarran'']].
The smaller model was dark green in color and featured several button controls running up the center of the device to a rectangular-shaped display screen capable of recorded-video playback. The larger model was brown and was held horizontally with a handle attached to the left of an angular, touch screen display. ({{DS9|The House of Quark|Blaze of Glory|Soldiers of the Empire|Tacking Into the Wind}})
:''Detailed photographs of both Klingon PADDs have surfaced online, notably at one prop manufacturer's website.'' [http://moviepropking.com/klingonpadd.htm] [http://moviepropking.com/klingonpaddlarge.htm]
<br clear=all>
[[Image:Quarren PADD.jpg|thumb|A Quarren PADD, [[2377]]]]
An example of PADDs appearing as distant as the [[Delta Quadrant]], similar devices were utilized by the slavers of the planet [[Quarra]] in [[2377]].
Golden-brown in color, these PADDs were roughly the same size as their [[Alpha Quadrant|Alpha]]/[[Beta Quadrant]] counterparts, but featured circular display screens with several button controls below. Among their functions, they were used to display missing persons reports. ({{VOY|Workforce|Workforce, Part II}})
:''The Quarren PADD was later repainted and appeared on ''Enterprise'' as at least two alien PADDs: a [[Xindi]] model in {{e|Zero Hour}} and as an alien bargainer's PADD in {{e|Borderland}}. It also appeared in the episode {{e|Stigma}} as the [[Denobulan]] neutron [[microscope]] controller.''
<br clear=all>
[[Image:Vulcan PADD 2152.jpg|thumb|A Vulcan PADD, [[2152]]]]
In service as early as the [[22nd century]], [[Vulcan]] PADDs came in a variety of builds and sizes, from angular to oval-shaped devices.
These PADDs were used by Vulcans stationed on distant planets, including Vulcans serving in the [[Interspecies Medical Exchange]] on [[Dekendi III]]. ({{ENT|Stigma}})
:''The Vulcan PADD featured most prominently in {{e|Stigma}} was in fact a repaint of the Bajoran PADD seen throughout ''[[Star Trek: Deep Space Nine]]''. This was the only episode in which Vulcan PADDs were featured.''
