EFO strikes again with an even smaller Bluetooth keyboard that is compatible with the iPhone and iPad. The Mini Bluetooth Wireless Keyboard has the footprint of a credit card, but manages to fit in F1 – F12 function keys, Tab, Cltr+Alt+Del keys and Multi-Media Key (Play, Pause, Next, Previous, Mute, Volume Up, Volume Down). It’s even back lit. This keyboard is available for pre-order through EFO for $32.00. The price will jump up to $40.00 in September when the devices start to ship.
