In a press release today, Amazon is introducing "Amazon Key" a service that lets couriers unlock your front door to deliver your packages. The new service exclusively for Prime members requires the Amazon Cloud Cam, and a smart lock for your front door. Amazon states "Each time a delivery driver requests access to a customer's home, Amazon verifies that the correct driver is at the right address, at the intended time, through an encrypted authentication process. Once this process is successfully completed, Amazon Cloud Cam starts recording and the door is then unlocked." Prime members can pre-order the Amazon Key In-Home Kit for $249.99 if you're in one of the 37 launch cities.
