Bluetooth headsets are expensive. Especially stereo Bluetooth headsets. Yet they all use the same factory default passcodes (more often than not "0000") to pair with them. And there is no way to change it! What this means is that anyone can steal your expensive prized accessory and pair it with their own phone. WTF!? No effing wonder they're such a high-theft item!
In case you haven't figured out where I'm going with this by now, my idea is for Bluetooth accessories to have changeable passcodes, like the security code on a cellphone.
This can be easily implemented in a number of ways. The easiest would be store programmed at the point of sale. My preferred method, however, would be a downloadable phone app that provides an interface for the owner to set it up and change it at his/her leisure.-- 21 Quest, Feb 14 2010 Or the numbers could be set up on the phone and the headset at time of manufacture and unchangeable thereafter, so you'd have to buy a headset with the same code as your phone. Some numbers could be made really rare and expensive, but their rarity would make them correspondingly less rewarding to steal.-- hippo, Feb 15 2010 random, halfbakery
