Microsoft has quietly unveiled a new “Modern Keyboard” with an integrated fingerprint reader. The Modern Keyboard is the successor to the Surface Keyboard, and looks identical. The only changes are a new fingerprint reader and the ability to use a cable for a wired connection instead of wireless.
Microsoft has integrated the fingerprint reader into the second Windows key on the right-hand side of the keyboard, and it can be used to log into Windows 10 or websites using Windows Hello. The new Modern Keyboard will work with Windows 10, MacOS, and the latest versions of Android.
