This is technology at work. The pen clipped on a pocket shirt or a court could actually be a camera recording every move that you make. The pen can record up to 3 hours of video footage which can later be transferred to a computer with the help of a USB.
The pen has a gloss black finish with a rubber finger grip with a built in microphone. It could pass for just a mere pen when in actual sense it is a serious recording tool capable of recording all that information as you may want it.
If not put to bad use, it could be a perfect replacement for taking minutes during meetings to avoid mixing up issues arising from the person taking minutes. It could be a fall back position in case of mixed messages minuted wrongly.
