Source-derived summary

The Nintendo e-Reader, commonly abbreviated as e-Reader, is an add-on manufactured by Nintendo for its Game Boy Advance handheld video game console. It has an LED scanner that reads "e-Reader cards" — paper cards with specially encoded data printed on them as dot codes. It was released in Japan in December 2001 and in North America in September 2002.

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. The cards themselves contain data, as opposed to unlocking data already on the device itself.

Usage and versions

Two versions were released in Japan: the original Card-e-Reader (カードeリーダー, Kādo-Ī-Rīdā) without a link cable port (released on December 1, 2001), which could read cards to display the data stored on those cards; and the Card-e-Reader+ (カードeリーダー+, Kādo-Ī-Rīdā Purasu) (released on June 27, 2003) which came with a link cable port to connect with GameCube and Game Boy Advance games. Outside of Japan, only a single version was released, the e-Reader, which has the same functionality as the Card-e-Reader+ and was released in North America on September 16, 2002. In Japan, the Card-e-Reader+ was bundled with Animal Forest e+, the enhanced re-release of the GameCube version of Animal Crossing.

The e-Reader can connect via Game Link cable to GameCube games such as Animal Crossing, and Game Boy Advance games such as Pokémon Ruby and Sapphire and Super Mario Advance 4: Super Mario Bros. 3.

Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Nintendo e-Reader”, the useful work is to connect “add-on manufactured by Nintendo” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 7, 2026. The linked authority identifier is Q1993197. 1 of 2 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 2001, 2002 and 2003.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
