From Geek.com: The Vioguard anti-bacterial keyboard has received U.S. FDA approval for use in healthcare, meaning that hospitals and other such sterile environments can use the keyboards.
The keyboard works by extending for use and retracting when it’s out of use. When it retracts into its housing, two germicidal 25-watt ultraviolet lights bake bacteria, viruses, and mold in seconds. The technology kills at least 99.99% of bugs like flu, MRSA, and other contagions. The fact that the Vioguard does it automatically makes it convenient for hospitals that would normally have to resort to manual cleaning.f
