It’s not exactly the most honourable of accessories, but definitely one of the more ingenious I’ve seen in awhile. This pen takes call through your cell phone via Bluetooth, and allows you to speak into the rear while listening to answers from a small headset. Don’t worry about proctors spotting the earpiece – it’s about half the size of a paper clip, and an even smaller nano earpiece is also available. Cheating isn’t cheap, though: the set will cost you €239, €349 if you want the nano earpiece.
