trailer lockers
Some of the locker cabinets might be swing (or slide) out to maximize the number of lockers.
These would be opened by like a Greyhound luggage locker is by the customer using a code.
All the lockers would have to be accessible. The stuff for wheelchair customers would be loaded in lockers accessible by a person in a wheelchair.
The trailers might be parked on site for two or three days before being brought back to the warehouse for restocking. A storage fee might be charged after so many days if the locker isn’t opened.
The system could allow for returns using an emptied locker.
No code, it would require you to tap your cellphone to the screen, or scan a QR code that the Amazon website would then cause to open the locker door.
