We don't know about you, but we're pretty prone to losing stuff -- everything from our precious phones, to our keys to, occasionally, our fellow bloggers. BiKN is a hardware and software-based solution that allows you to track you loved ones and things using simple 802.15.4 radio tech instead of battery-sucking GPS. The two hardware components that will be shipping later this month are an iPhone case, which connects through the 30-pin connector and tags which you can attach to keys, bags, or the belts of wandering children. You can leash items to you using the free app so that an alarm will sound -- on both ends if the person or item wanders out of a particular range. You can also simply ping them if you've misplaced them. It even simply measures how far away another phone or tag is. And, since it's a two way system with a battery integrated in the case, if you lose your iPhone and the battery is dead you can still find it using one of the tags. A package containing the case and one tag will be available for $100, while a kit with two tags will retail for $120. Additional tags can be purchased in packs of two for $50.
