Keeping track of your stuff can be easier than you think thanks to a new device that keeps an eye on your belongings. Just stick a special tag to anything you don’t want to lose—keys, tablet, purse, luggage, passport, phone—and add an app to your IPhone or IPad. Like magic, pixie dust appears so you can quickly find things, even through walls and under cushions. Easy-to-use augmented reality technology links the app with what you value most. To find what’s yours with Pixie, go to Amazon or getpixie-.com.
