Carddass (カードダス Kādodasu) is a name of Bandai's card vending machines and a generic term given to the cards sold by these machines. The name comes from AMeDAS (Automated Meterological Data Acquisition System), a system in Japan used for gathering weather data. The aim behind this naming is to make Carddass an information source for kids.
The first Carddass, released in 1988, is based on the Saint Seiya anime series. In the past, Carddass was for trading and collection only. But since trading card games like Magic: The Gathering have become popular in Japan, more and more Carddass were made in the form of trading cards that can be played in a game.
Apart from Saint Seiya, many popular anime, manga, tokusatsu and video game series have been made into Carddass, including Bleach, Chrono Trigger, Code Geass, Digimon, Dr. Slump, Dragon Ball, Dragon Quest, Final Fantasy, Fullmetal Alchemist, Gin Tama, Gundam, Hunter x Hunter, InuYasha, Kamen Rider, Kinnikuman, Mario, Mega Man, Nadia: The Secret of Blue Water, Naruto, Neon Genesis Evangelion, One Piece, Pokémon, Ranma ½, Revolutionary Girl Utena, Rurouni Kenshin, Sailor Moon, Slam Dunk, Soul Eater, Street Fighter, Toriko, Ultraman, YuYu Hakusho, Yu-Gi-Oh!, and Zatch Bell!.
A digital version of the game, Data Carddass, was introduced in 2005. This series revolves around arcade machines that can read specially designed cards to access in-game content, such as weapons, characters or clothes. Later AR Carddass was introduced, which uses augmented reality features in smartphones, and the Net Carddass that contains online functionality.
