In 2006 the Mattel HyperScan was a short lived console with an interesting concept: Enhance a classic videogame with collectible RFID cards. A concept that was picked up in a similar form by the Skylanders games and maybe someday will be used in Nintendo’s new Wii U console.
Playing the games (and scanning cards) can be described as interesting but not as fun. The games seem unfinished and buggy. And then there are the long loading times, a problem already the NeoGeo CD suffered from back in the days.
There were even some first steps with homebrew programs here and here.
