This is really a clone of the Fidelity Chess Chard and has the very same features. The chess program is the same, not really a strong program. You can fit the card and the board with the magnetic pieces in your pocket. Interesting concept.
It has some nice features such as: set up positions, warning about threats, allows player to change sides and you can get up to 65 hours of play with a battery (3-volt, lithium, type 2032)
