Also known as: ライダーカード
The collectable item of Kamen Rider DCD, used with the Decadriver (and NeoDecadriver), the Diendriver, and the Zein Driver in their one-time use Zein Card iteration. They are cards which contain the powers of past (or post-series) Kamen Riders, allowing one to transform into the Rider in question. When paired with the K-Touch (and K-Touch21), the cards can be used to access stronger forms.
