01 / Selection mapping
Show that the selected product or reference opens the intended compartment. Repeat after refill and after a position is unavailable. Wrong mapping creates a customer issue even if payment and a lock command work.
02 / Highest-row reach
Use a top position in the test and consider realistic customer reach and destination access requirements. No compartment height or accessibility certificate was supplied.
03 / Clear opening
Measure usable clearance including the hinge, fittings and door movement. Test at the intended inflation state. A panel dimension is not the same as the opening a ball must pass through.
04 / Ball removal
Retrieve the actual retail ball without forcing the door or scraping it. Use any included packaging. A large round item should not need to fall into the public approach to be collected.
05 / Door closing
Demonstrate normal closing and the response to a door left open. Identify any installed state sensor. A lock command is not evidence that a door has physically latched.
06 / One sale unit
Confirm whether a position carries one ball or another approved unit, and test that exact loading. One illustrated ball does not establish capacity for other formats.
07 / Stock update
Trace a completed purchase and ask when stock decreases. Explain access without collection where supported. Door opening and product removal need not mean the same thing in the counter.
08 / Empty handling
Make a test position unavailable and try to select it. Demonstrate how refill restores availability. A known-empty position should follow the configured sale-blocking rule.
09 / Pending selections
Test an abandoned selection and a pending payment. Ask how long a position is reserved. Avoid assigning one stocked ball to conflicting transactions.
10 / Payment decline
Run a decline with the fitted provider and observe screen instructions and access behaviour. A decline should be distinguishable from an authorised charge or machine fault.
11 / Paid but closed
Use the agreed safe test for payment without access. Trace the event and support procedure. Define retry, assistance and refund responsibility instead of assuming automatic recovery.
12 / Open but uncollected
Ask how the actual hardware represents opening without removal, if it can distinguish that state. Lighting and transparent panels do not prove ball-presence detection.
13 / Staff access
Show authorised service access to the compartment and lock. Keep it separate from customer access. The public door layout is not a maintenance drawing.
14 / Known refill
Load a known quantity through the normal account process and check the availability change. Physical loading and software records should use the same sold unit.
15 / Variant change
Update an approved ball variant, product image and price at the correct position. Retest fit where needed. Similar appearance does not establish the same size, cost or offer.
16 / Price consistency
Publish a supported price change and compare the display, charge and sale record. Remote pricing helps only when customer information agrees with the amount charged.
17 / Network loss
Ask for the supported offline sequence and supplier-approved connection interruption test. Offline payments and cached access are configuration-dependent.
18 / Restart recovery
Agree a safe interruption and restart test, then check pending payment, access and stock state. Do not assume a restart resolves every interrupted purchase.
19 / Staff permissions
Test included operator and administrator roles for stock, pricing and access changes. Enough permission to work does not require sharing every owner credential.
20 / Remote commands
Ask whether remote access commands exist, are restricted and are logged. Quote them separately. Management reports do not automatically include remote unlocking.
21 / Status meaning
Review actual fault and online events and identify the source controller or sensor. An online unit can still have a payment problem or unusable position.
22 / Operator contact
Test the contact displayed on the cabinet and find the customer transaction reference. A practical contact route reduces time spent reconstructing an issue.
23 / Panels and seals
Inspect edges, transparent fronts, hinges and fitted seals. Request material and environmental data. The renderings do not establish impact strength or salt-air protection.
24 / Cleaning procedure
Show approved cleaning around the display, terminal, doors and electrical areas. Sand and moisture need the equipment instructions rather than guessed treatment.
25 / Canopy envelope
Measure overhang, installed height and service space, including separately shipped components. Cabinet footprint alone does not describe the canopy clearance.
26 / Base stability
Check castor rating, brakes, levelling or anchoring and the final approved surface. Wheels do not establish road-transport suitability or wind resistance.
27 / Test reconciliation
Correct test purchases and manual removals, then record remaining usable stock. Unrecorded test access can distort the first public trading count.
28 / Written acceptance
Keep the configuration, sample-test result, account scope and service contacts with the unit. A repeatable acceptance record is more useful than assuming every illustrated feature is included.
