You thought Carddas were the only type of cards? Well, apparently, there's a whole slew of different types of cards.

Carddass (Bandai, 20 yen ea.)

These cards were sold in vending machines that looked like gum ball machines. There were 2 types of machines, a Carddas 20 that spit out 1 card, and a Carddas 100 that dispensed a 5-card pack for a 100 yen coin.

Bandai produced Carddas for other anime, but DB appeared to be by far the most popular. Carddas could be used in a game of war with opponents, or collected on its own. The first DB cards came out in 1988.

Whaddaheck does "Carddas" mean? Well, there's the overt pun that combines "card" and "dasu," the Japanese word for "dispense" (among other meanings). The DB Daizenshuu appendix also states that at the time the idea for Carddas was conceived, the Japanese weather satellite, "Amedasu" was in the news. Since the satellite was an information source for weather, the new cards were to be an information source for kids. There is also a popular Japanese information book / encyclopedia called "Imidas" (dispense meaning).

Jumbo Carddas (Bandai, 100 yen ea.)
Larger cards (almost shitajiki size) meant more for collecting than playing games.

Super Battle Cards (Bandai, 20 yen ea.)
Another type of Carddas, these were specially made for battle games.

Visual Adventure Cards (Bandai)
Yet another type of Carddass, these cards sport art by Toriyama Akira that have been rendered as cells.

Character Collection Cards (Bandai)
As you can guess, they portray most of the characters from DB and is also a type of Carddass.

PP Cards, DBZ & DBGT (Amada, 20 yen ea. / also comes in packs of 34)
These cards, similar to Carddas, portrayed characters and scenes from the anime, but are made by a different company.
DBZ Pocket Case Original Collection (Amada, 280 yen)
This is a set that comes with 6 PP cards, 1 "holographic" card, and a plastic container to hold the cards in.

Laminated Cards / "Idol Cards", DBZ & DBGT (Amada, 100 yen ea.)
These are cards are somewhat larger than Carddas, and in essence appear to be a miniature shitajiki (pencil board).
Many pirated laminated cards exist. If the back of your card says "AGFA" or "Fuji" instead of "Dragon Ball," oops.

DBZ Hero Cards (Amada, 200 yen / 10 per pack, 100 cards in a series)
These cards were sold in sealed packs and were meant solely for collecting. There appears to have been at least 4 series

DBZ Trading Collection (Amada, 300 yen / 12 per pack, 114 cards in a series) These were also sold in sealed pack, and again, were meant more for collecting than playing games.

DBGT Trading Collection (Amada, 300 yen / 12 per pack, 101 cards in a series)

DBGT Trading Collection: Chromium Cards (Amada, 300 yen / 5 per pack, 45 total)
Appears to be a deluxe version of the above.

Telephone Cards (NTT)
Appears as though only a limited number of "official" DB telecas (telephone cards) were issued. I have seen a number of telephone card look-a-likes that are not real phone cards.

Carddas System File, Carddas Station (Bandai)
A binder to keep all of your Carddas.

Carddas Refill Pockets (Bandai, 380 yen per package)
Extra pages for the System File or Station.

Card Star (Amada, 2,700 yen)
This is a "rotary card showcase" that holds 100 cards. Can store any type of card that Amada has released.
