【18 U.S.C 2257】

Amazon8 U.S.C 2257giving its app a new feature to help holiday shoppers keep track of what's in their packages.

The company updated its iPhone app with a new feature that uses the phone's camera to help detect what's inside your packages without opening them.

Dubbed, "Package X-Ray," the feature uses your iPhone's camera to scan the barcode on the package. Once scanned, the app will show which of your orders are inside.

You can try it for yourself if you have the latest version of Amazon's iOS app (no word yet on Android availability) by tapping the camera icon next to the search bar and selecting "Package X-Ray."

While admittedly not as cool as actual x-ray vision, the feature should be particularly useful to for holiday shopping -- especially if you're trying to keep a particular shipment away from prying eyes. Even if you order multiple orders at once, Amazon doesn't always ship items together, so you could have multiple packages show up simultaneously.

Amazon, of course, is already gearing up for Black Friday with sales on Echo, Kindle and Fire TV devices, as well as televisions and other electronics. Now you can order as much as you want without worrying about keeping track of when they all show up at your door.
