A wall of doors does not, by itself, tell staff where an order is, who owns a failed collection, or whether the aisle still works at busy hour. Separate the metal cabinet from the order path.
Count doors you can see, write the failed-pickup rule, and measure the aisle on the premises. Take width, height, and parcels per hour from the manufacturer sheet for that bank, and keep the aisle measurement with the date you visited.

What to write next to the cabinet
- How many doors are in the bank you are considering, counted on a drawing or on site, with the date of the count?
- Which system tells a customer which door to open, and what they do if the code fails?
- How long an uncollected parcel stays, and who returns it?
- Is the standing space clear of the loose mats and wet patches that slip guidance is written to address?
The UK Health and Safety Executive slips index is the pointer for that last question. It covers causes, roles, and the cost of slip and trip accidents. Use it for the floor, and use the manufacturer sheet for the hardware.
The picture shows a plain grey cabinet, with no logo and no on-screen payment brand.
Staffed self-service, where a person still finishes a failed payment, is the neighbouring list: checklist before self-service. When a cabinet authorizes payment and dispenses live inventory instead of holding prepaid parcels, use smart vending machines: retail footprint, power, ADA, and network site prep. All three sit in retail technology, while the two-step scan-to-bin staging rack workflow, Little’s Law bin sizing, 2010 ADA pickup signage, and expired-order return-to-stock rules sit in BOPIS retail: in-store pickup staging racks, workflow, and ADA signage.
Measure the aisle with a tape on the day you visit the premises, and write that number in your own note beside the door count and the failed-pickup rule. That measurement belongs to the premises you visited.
