BiKN's thumb-size tags help you keep track of valuables using your iPhone. Attach them to any object and snap your phone into the BiKN case, which communicates with the tags via a radio signal. Using the myBiKN app, you can view a map on your iPhone of tagged items within a distance of several hundred feet, page them so they beep, or set an alarm to go off if a tag leaves a preset perimeter. The tags worked perfectly during testing, sounding an alarm even when our iPhone was off. cost: Starting at $100 for one tag and an iPhone case
