Amazon is exploring ways to deliver items to your car trunk and the inside of your home

Amazon  is working to make sure your packages get inside the front door, or even into your car. The company is in advanced talks to forge a partnership with Phrame, a maker of smart license plates that allow items to be delivered to a car's trunk. Phrame's product fits around a license plate and contains a secure box that holds the keys to the car.

Users unlock the box with their smartphone, and can grant access to others — such as delivery drivers — remotely. At the same time, Amazon is developing a smart doorbell device that would give delivery drivers one-time access to a person's home to drop off items.
