Interesting. Thank you for your reply. Have you heard of Amazon Key( electronic lock so that owner's door can be opened for delivery driver. [https://www.amazon.com/b?&node=17285120011] https://www.amazon.com/b?&node=17285120011]) Do you have any thoughts on that such as why Amazon would do that and if UPS would do something similar?
