E Reader for Nintendo Game Boy Advance
The e-Reader is an accessory for use with the Game Boy Advance that reads information from collectible trading cards and translates it on the GBA into standalone games or enhancements to some traditional games. The e Reader connects into the GBA cartridge slot and can also connect to another GBA or even a GameCube. Players simply slide the paper cards through the e-Reader much as you slide a credit card through a point-of-purchase machine at a grocery store. When you do this, the unit scans the codes imprinted on the card and stores the information in its 1-megabit flash ROM for as long as the power is on.
