Re^2: problem related to project key counter

[psini]

Hire a keyboard company to make keyboards that emit small radio signals for every key typed (along with a keyboard id), and have a central collecting receiver.

Wireless keyboards sell at about $10.

They are safe just about as a cardboard armor, so it shouldn't be so difficult to build a centralized receiver.

This is the main reason why I never used and will never use them...

I read a report once, that in general, you don't even need radio waves. Each keyboard key emits square waves on the cable, which can be picked up within a few feet, OR each key makes a distinct sound when pressed, which can be picked up by a microphone.

Although they are not as widely available as audio bugs, I'm convinced that there are computer bugs, that someone can place under your desk, and pickup your keyboard cable.
