Barcode Battler Senki: Super Senshi Shutsugeki Seyo!
The original Barcode Battler game was a handheld LCD where you scanned barcodes to see what happened. You were encouraged to try it with barcodes everywhere. It was popular enough in Japan to warrant a sequel, and that sequel came out with a new device for the Super Famicom, along with a game. This isn’t the device, but it is the game for it! One of the most unique game releases we can think of.
