A new device called the HipKey can help to keep track of ones belongings. HipKey, shaped like a crescent moon, uses Bluetooth 4.0 technology to reach a range of up to 50 meters. The battery life is up to three or four weeks and can be re-charged by micro-USB. HipKey is compatible with iOS devices. The distance triggered alarm system issues a warning when your iPhone and hipKey get separated. The Motion mode sounds an alert if someone moves your belongings which are attached to the hipKey. It can also assist with keeping pets or children within reach by using the Child mode feature, while the Find me mode allows you to quickly find an iPhone or iPad.
