The Apple Wireless Keyboard works with the Bluetooth option in your Mac to provide a cable-free way to interact with your system at a distance of up to 10 meters (33 feet).
A robust 128-bit over-the-air encryption keeps sensitive information safe as it is being typed. Apple is the first to deliver intelligent software to prevent interference with Airport wireless networks without any performance degradation. The full-size, yet compact wireless keyboard takes up very little space on the desktop and easily fits on a user's lap.
