Microsoft is introducing a new line of keyboards and mice this week, including some with fingerprint readers that lets users scan a finger instead of having to enter a log-in name and password when accessing online services or logging on to the PC.

A keyboard, mouse, and a stand-alone fingerprint reader were added to Microsoft's hardware lineup. The products are aimed at consumers and are meant for convenience use only. Strong, or hard-to-guess passwords are still recommended for sensitive data such as financial information or for access to corporate networks, Microsoft says.

The Optical Desktop with Fingerprint Reader is expected to retail for $109, while the Wireless IntelliMouse Explorer with Fingerprint Reader will sell for $85. The Fingerprint Reader by itself is expected to retail for $55.
