The is a belt that gives Tsukasa Kadoya the ability to become Kamen Rider Decade, based around the Rider Cards. It was created alongside the Ride Booker, as well as Diend's Diendriver, by scientists of Dai-Shocker, which included Joji Yuki.
==NeoDecadriver==
Decade returns in Kamen Rider Zi-O with an upgraded version of the Decadriver called the ​, which is colored solid magenta and bears the symbols of all 20 Heisei Riders minus Decade and Zi-O. This version can use the powers of all Heisei Riders up to Zi-O.
==Design==
When Decade transform into Complete Form, a special attachment part will materialize on Decadriver's right slot. This attachment holds the card-reading unit when replaced by the K-Touch.
==Functionality==
By inserting a card into the Decadriver, Decade can invoke the cards' abilities. In Complete Form, the Decadriver is moved to the right side of his belt where Decade inserts his Final Attack Ride Cards and activates them by touching the Decadriver's window.
As seen in , along with Blade's Blay Rouzer and Ryuki's Dragvisor, the Decadriver is also compatible with at least some of the used by the . This is shown when he is given the Reflecloud card by to counter Kani Lazer's beam attack.
The NeoDecadriver gives Decade the ability to transform into his successors from Double to Zi-O, as well as letting him access all of a Rider's abilities without requiring a Form Ride, as seen when he uses Agito's Flame Saber while in Ground Form  and Wizard's water magic while in Flame Style.

===Form Changes===
When Kamen Rider Decade transforms into the previous Nine Heisei Riders using the Kamen Ride Cards, he still appears sporting the Decadriver in the place of their respective belts, to use his various Attack Ride cards. However when he disguised himself as Kamen Rider 1, the Decadriver took on the appearance of Rider 1's Typhoon belt, unlike other Kamen Rides where the Decadriver is still present. It changed back when the Decadriver/Typhoon was struck by as . It is unknown if this is a property of the card itself or a yet-undemonstrated ability of Decade's. 
==History==
The Decadriver and Ride Booker were created for Tsukasa's use, having been the Great Leader of Dai-Shocker before losing his memory. However, both items were abandoned and left to corrode before they were found by Natsumi Hikari amongst rubble during the destruction of the worlds. Recognizing them from her dream of Decade, she gave them to Tsukasa who was trapped in another dimension, with the items being restored as they passed through the dimensional wall. Taking the Kamen Ride: Decade card from the Ride Booker, Tsukasa inserted it into the Decadriver, transforming for the first time to defeat the rampaging monsters. 
==Jumbo Decadriver==
In the summer film, Decade is transformed by a Final FormRide Card into the , a larger version of the Decadriver which is worn by a Kamen Ride Card-summoned Kamen Rider J to transform into Decade Complete Form . This form is identical to the usual Complete Form, apart from the fact that Decade is now many times larger, and wears the Decadriver on the front of his belt, with no K-Touch.
The name of the Decadriver is misspelt as "Decaderiver" on this card.

==Behind the Scenes==
===Portrayal===
The voice of the Decadriver (and Neo), as well as the Diendriver, K-Touch, and Rider Battle tournament announcer in All Riders vs. Dai-Shocker, is provided by .
===DX Decadriver's unused sound===
The DX Decadriver has "FINAL RIDE", and "RIDE" announcements, none of the Rider Cards released can activate these sounds.
===Complete Selection Modification Decadriver's unused sounds===
Released in March 2015, the CSM Decadriver contains newly-recorded transformation sounds for Double, OOO, Fourze, Wizard, Gaim and Drive, as well as some of Diend's Rider Cards. While the Diend Cards foreshadowed the eventual release of the CSM Diendriver, the sounds for the later Heisei Riders could only be accessed by "hacking" the belt (such as creating fake "cards" by drawing or printing the barcodes onto a blank slip of paper) since proper Rider Cards were never released, until the eventual reveal of the official Rider Cards of Heisei Phase 2 Riders from Double to Zi-O, in which were included in the release of the DX version of NeoDecadriver. It is also possible to use the NeoDecadriver version of Kamen Ride cards from Double to Drive on the CSM Decadriver.
==Notes==
*If the Showa Riders' cards, as well as the Kamen Rider Skull card from the CSM Decadriver is used on the DX NeoDecadriver, the transformation announcement is still retained. However, the transformation SFX of each Showa Rider of their respective cards (i.e., the Typhoon noises from 1 & 2), as well as Skull's, are omitted. https://www.youtube.com/watch?v=Cs8Iknv8k64
*If the final form cards are inserted in the DX NeoDecadriver, the belt will say the full name of the form "(name of final form)!" with the corresponding sounds and voice clips of Heisei Riders' final forms, unlike the CSM version where it only said the name of the final form.
*If the Form Ride and Attack Ride cards from CSM are inserted in the DX NeoDecadriver, the belt will say the corresponding Riders' name instead of the names of attacks and names of their forms.
*When inserting Diend's Kamen Ride card from the CSM Diendriver into the DX NeoDecadriver, it will play Diend's transformation sound from the CSM Diendriver.
*If the Secondary, Tertiary and Extra Riders' cards from the CSM Diendriver are inserted into the DX NeoDecadriver, the announcement will only say "Kamen Rider" instead of their corresponding Riders' names.
*While the original Decadriver would only play sound effects during a Kamen Ride transformation, the NeoDecadriver includes unique voice clips such as Kamen Rider Build's "Hagane no Moonsault!" voiced by KORBY. The DX NeoDecadriver demonstrates that this is a retroactive change, with the original nine Heisei Riders having extended transformation sounds that sometimes gain voice clips such as Faiz's "Complete!" voiced by Takehiko Kano or Kabuto's "Change: Beetle!" voiced by Surage Gajria.
*Ever since Decade, all Rider belts have been officially referred to as "Drivers". The only exception was the Mage's Belt in Wizard and some secondary belts in Zero-One like the A.I.M.S. Shotriser, the MetsubouJinrai Forceriser and the ZAIA Slashriser.
**However, Faiz was the first Rider to use the term of "Driver". In this case, the SB-555B Faiz Driver.
**This trend would be broken in 2024 by Kamen Rider Gavv's Henshin Belt Gavv, being the first main transformation device since to not have Driver in the name.
*There are no sounds added for the NeoDecadriver influencing Kamen Rider Zero-One and its Rider Cards.
