Carddas(カードダスKādodasu) is a name given to Bandai's card vending machines and, thus, 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 Carddas an information source for kids. Carddas is a registered trademark of Bandai. In 2006, a Super Sentai-based trading card game, Rangers Strike, was released in commemoration of the Super Sentai Series' 30th Anniversary. In 2007, Carddas started to sell Top Trumps in Japan.
