The latest innovation from Amazon is the "Amazon Key", a device which gives their delivery people access to inside your home. No more worrying about your courier package being stolen from outside your front door!

As more and more people embrace ordering online, this innovation will surely be embraced by some. It includes a camera so you can see the delivery live if you wish.
