Walmart tests smart lock delivery service

Why the future could mean delivery straight into your fridge — Walmart — “Here’s how the test will work: I place an order on Walmart.com for several items, even groceries. When my order is ready, a Deliv driver will retrieve my items and bring them to my home. If no one answers the doorbell, he or she will have a one-time passcode that I’ve pre-authorized which will open my home’s smart lock.”
