The hipKey is a handy little device that syncs with iPhones and iPads to ensure that belongings are not lost or misplaced. Shaped like a mini crescent moon, the hipKey can be attached to just about anything including zippers, bags, belt loops and more. The hipKey is lightweight enough not to be a bother. Instead, people will praise their hipKey for helping them not lose important things, including their children.

Essentially, when a person wearing the hipKey strays too far from specific people or items, it alerts them immediately. The hipKey also has a motion mode that triggers the alarm if anyone so much as moves the key. It was designed by Hippih, a studio based in Copenhagen.
