Nintendo e-Reader

The e-Reader is a device made by Nintendo. When plugged into a Game Boy Advance, it can scan cards, which have specially encoded data printed on them, to perform various functions, such as play a game or interact with another game.

Use in Animal Crossing
When the e-Reader and Game Boy Advance are connected to a Nintendo GameCube playing, cards from the Animal Crossing-e series can be used to affect gameplay, including unlocking rare NES games. This does not work in the P.A.L version.

Cards
There are 4 different card sets. Once scanned, they can give the following items:


 * The two NES cards can give players the game shown on the card.
 * K.K cards that gives music.
 * A promotional card that comes with the e-reader gives a surprise item.
 * In the Japanese version of Animal Crossing, the player can scan 'Character Cards' that makes the designated character move into the player's town.
