Digital Leash

Travelers who worry about leaving their phone in a hotel room or airport will like this small Bluetooth device designed to be worn on a keychain. The Zomm monitors the signal strength of a Bluetooth connection to your phone and sounds an alert if you get more than a few yards away. It can also be used as a speakerphone and as a panic button to call 911.
