Thieves suck. You should be able to track down the people who steal your stuff and kick them repeatedly in the gonads. A new antitheft device that uses Bluetooth called Nio is now available in the US for purchase through Amazon.
The Nio tags can be used to protect all sorts of electronic devices like mobile phones, laptops and the data on the devices. The tags can be set with a security zone of up to 80 feet and when the devices move more than the set distance apart both the tag and the device it is protecting produce an audible alarm.
