Parents of the 21st century must be exceptionally bad at keeping track of their kids, given that we've seen a small handful of devices trying to achieve what parents somehow have been able to do for millennia without the benefit of such gadgetry. The latest addition to the party is Tranwo's Digital Wireless Child Tracker, which comes with a parent and child unit, allowing each to call for the other via a series of beeps. Basically, when one person signals for the other, the buzzers in each device will sound, and will get faster and faster as parent and child get closer together. No word on how much nor when this ridiculous invention will hit the streets, but the five-language manual indicates that Tranwo is probably aiming for a global release.
