Microsoft Wireless Desktop 900 Keyboard and mouse view

Wireless without worry

This slim and stylish mouse and keyboard are built for comfort. The keyboard actually helps protect your information with Advanced Encryption Standard (AES), which encrypts your keystrokes so you can go wireless while staying secure. Each keyboard is permanently paired with its receiver at the factory, so nothing is ever shared over the air. Combine that with an average battery life of two years, and you've got a wireless desktop that's perfect for using with your USB-enabled tablet, laptop, or PC.
