Amazon Key will be able to unlock your front door Photo: YouTube
Amazon.com is rolling out the future. Amazon Key will begin in 37 cities in the U.S.
Amazon Key lets people into your house, and there's a camera you can use to watch them, Amazon Cloud Cam. This service is being offered for between $US6 and $20, depending on how good you want the video, and how many cameras. You can have up to 10.
Plus you need to pay for the cameras, and pay for a new lock on your front door, $250.
