ZZZ(notgame):E-reader

The e-Reader is a discontinued device made by Nintendo for its Game Boy Advance portable video game system. It was first released in Japan in December 2001, with a North American release following in September 2002. It has a LED scanner that reads "e-Reader cards", paper cards with specially encoded data printed on them.

Depending on the card and associated game, the e-cards are typically used in a key-like function to unlock secret items, levels, or play mini-games when swiped through the reader. See below for a comprehensive list of cards and their functions. The cards themselves contain data, as opposed to unlocking data already on the device itself.

The e-Reader is not a console, but an add-on device, like the Game Boy Camera or the Game Gear TV Tuner.
