A company called A1Pro has released limited details on a new type of keyboard they claim can read your handwriting as an added security feature. As of now it seems that it can only read your handwriting in a gatekeeper role, allowing you access to your computer, no word on whether you can write on a MS Word instead of typing.
Based on the picture, we can tell that it uses USB, features a touchscreen to the right, and a stylus in which to write with. It can also be used to read foreign language letters, characters, or symbols. It currently sells for $25.48, in black.
Since it’s pretty cheap, it may be worth to buy it if you need a new keyboard and to test out its security features.
