In my day, if I wanted to cheat on a test I had to look over to what the smart girl was working on, or keep answers in my pocket to check in the bathroom.
This fancy pen has a small mic and a tiny earpiece, letting it function as a mobile phone that's difficult to detect in class. Of course, you need to whisper in it, which is inherently risky, but not impossible to pull off. What's really going to be foolproof is the next generation of these things, a pen that streams live video from whatever the pen is looking at over the web. Combine that with that tiny earpiece and you've got a pretty foolproof way to stay in touch with someone with a Wikipedia connection and a vested interest in you passing that stupid class.
