Super Mario Advance 4: Super Mario Bros. 3 e-Reader cards

Super Mario Advance 4: Super Mario Bros. 3 features e-Reader compatibility, in that it can link up to a second Game Boy Advance with an e-Reader. Upon scanning in one of three types of cards, something will then be triggered in the game. This feature is normally absent in the European version of the game, but it can be enabled using a cheat device. These are the types of cards that were released:
 * Power-Up Cards upload an item (or a set of items) into either Mario or Luigi's inventory. There is no limit as to how many times an item card can be used. A variant type of Power-Up Cards are Switch Cards, which will trigger something in the game upon being scanned.
 * Demo Cards play a movie of Mario speedrunning through a level, collecting enough coins in a certain level to trigger a White Mushroom House, or racking up numerous 1-Up Mushrooms via a special trick.
 * Level Cards upload a brand-new level into the game, which can be played in World-e. Note that only 32 levels can be saved on the game at a time, and up to 73 levels can be listed.

Cards
The majority of the cards were released in two series (sets) of cards. However, a few cards were included with brand new copies of the game. While most copies only came with two cards, copies purchased at Wal-Mart early on came with an additional five cards.

In Japan, while most cards were still released within two series, things worked differently. Instead of each pack containing every card for that series, the cards were released in a format similar to trading cards, where each pack had five random cards. The cards had a uniformity to their arrangement within the packs, though it changed between Series 1 and 2. In Series 1, it went one level, one demo, three power-ups. In Series 2, it went two levels, two demos, one power-up. In both series, however, an extra level was included if the pack contained a classic level. This deducted a power-up from the pack. Excluding promotional cards and Switch Cards, Japanese power-up cards do not depict or mention what item the player will get, leaving it a surprise until the card is scanned.

All North American cards (excluding promotional cards) were released in Series 1 in Japan.

While 106 cards existed in Japan, only 43 cards were made available to foreign markets. Therefore, there are over twenty levels that remain unavailable to non-Japanese players. Other missing cards include various Switch Cards and Boomerangs. However, all versions of the game on the Wii U Virtual Console support all the e-Reader levels by default including levels formerly exclusive to Japan.

Note: Due to the discontinuation of the e-Reader, newer copies of the game do not come with cards, although the game itself is still compatible with the e-Reader. When ported to the Wii U in 2016, largely because of it lacking e-Reader compatibility, the level cards are pre-included into the world-e section (also marking the first time the Japanese-exclusive cards were made playable and localized outside Japan). However, the player cannot use any item or demo cards.
