Meet the iTraq: a global location tracker almost as small as a credit card that relies on cellular towers to report its location. That means you will be able to track your valuable items almost anywhere. iTraq uses Cell-ID technology and lets you adjust how often iTraq should report its location, which means the battery can last up to 3 years.
The device may be not as accurate as an advanced GPS but it does report the location of your valuable items. Geofencing is also available. The companion app lets you manage all your iTraqs conveniently. You can find this project on Indiegogo.
