Once again I can’t give secu4 the credit for being the first to come up with this idea, but I like the fact they’ve managed to get their BlueWatchDog security ‘dongle’ almost as thin as a credit card, making it less of an inconvenience to actually use. The idea is you stash one of these cards inside something you don’t want to go missing, and then connect it to your cellphone over Bluetooth.
Everything is hunky-dory until you and said article are separated by a preset distance, anywhere between 1 and 30 meters. At that point an alarm on your cellphone will sound letting you know the protected item has been forgotten or taken, and the BlueWatchDog itself will emit a 100db alarm serving as a reminder and/or a deterrent. The system is compatible with a wide variety of phones, though oddly enough not the iPhone which was supposed to be supported sometime this year. And while ~$95 (€69.99) isn’t chump change by any means, it could be cheaper than having to replace a laptop or other more expensive device.
