In the parcel storage box in front of the front door, which can prevent the loss of delivery, no design has yet emerged to fix the eyes or dominate the market. Demand is steadily increasing, but such products are rampant. However, it is expected that the city will soon see new items that will be standard designs in the suburbs. Walmart, which enjoyed a boom in food delivery services during the Pandemic period, faced the fact that consumers' inconvenience, which is difficult to meet delivery times, is the limit of service growth.

In response, Wal-Mart decided to introduce Smart Box, an IoT device, in partnership with HomeValet, a shipping logistics company.
