The e-Reader is a gaming peripheral developed by Nintendo. When paired with a compatible portable gaming device (e.g.Game Boy Advance), it can be used to scan e-cards which have specially encoded data printed on them, to perform various functions such as uploading data or unlocking game features. Some cards may also contain game data to play mini-games or even retro titles such as the ports of NES titles, for play on the GBA.
e-Reader cards work using Dot Code Technology developed by with Olympus Optical Co., Ltd. Each card can hold up to two code strips, one long strip holding up to 2.2 kilobytes of information and a shorter strip containing 1.4 kilobytes. The e-Reader peripheral itself uses 64 Mb mask ROM and 1 Mb flash memory.
