Ghost Driver

The Ghost Driver (ゴーストドライバー) is the transformation belt used by Kamen Riders Ghost and Specter. They transform by using the Ghost Eyecons.

Chikara Saionji carries an unfinished Ghost Driver connected to electronics inside his briefcase to create Ghost Eyecons from unsealed Parka Ghosts. It presumably is incapable of being used for transformation due to its incomplete state, as it lacks a trigger mechanism.

According to Sennin, one needs to have a functioning Ghost Driver in order to make a wish with the 15 Heroic Eyecons.

Functionality
To transform, the user opens the Ghost Driver, presses the button on a Ghost Eyecon to its Standby Time setting, and inserts it into the belt's buckle before closing it to secure the Eyecon in place. Afterwards, the user pulls the lever out and then pushes it back in place to open the "eye" of the belt, which activates the Eyecon's Transformation Time setting to summon its respective Parka Ghost and fuse with the user's body, thus completing their transformation into either Kamen Rider Ghost or Kamen Rider Specter.

To initiate a Ghost Eyecon's finisher, the user must pull and push the lever a second time to activate the Eyecon's Move Invocation Time setting. Alternatively, the Ghost Driver can activate the finishers of either Ghost's Gan Gun Saber or Specter's Gan Gun Hand by scanning the eyeball-like insignia found on the weapons' hilt with the Eyecon currently placed within the Ghost Driver.

By pulling and pushing the lever four times, the user can activate the Ghost Driver's Oomedama (オオメダマ) function where it manifests a giant construct of a Ghost Eyecon for the user to kick and destroy any giant-sized Ganma Holes before they have a chance to bring more Ganma into the world.

In order to have the Ghost Driver cancel the transformation, the user must remove the Ghost Eyecon currently placed in its buckle and then close it back up.
