How an AI Vending Machine Works
WEIMI operation guide
From product setup to a checked shopping basket
A WEIMI vision-based vending fridge connects access, item recognition, payment and operator records. Successful operation depends on an approved product library and a tested shelf layout—not simply putting products behind a camera.
Confirm the hardware, software and payment configuration for the machine you order.
This page focuses on WEIMI product setup, shopping sessions and operator checks. For the broader technology explanation and transaction architecture, read how AI vending machines work.
01 | SHOPPING SESSION
How the WEIMI shopping session works
A customer uses an enabled payment or access method, opens the door, selects registered products and closes the door. The system determines the basket for checkout. The available methods and exception handling depend on the deployed terminal, acquiring service and software configuration.
Authorize access
Follow the on-screen instructions for the supported card, wallet or other enabled method. Where preauthorization is used, a temporary authorization is different from the final purchase charge.
Select products
Take the products you want and follow the machine's instructions for returning an item. Keep packaging visible and avoid obstructing the camera view.
Close the door
Allow the session to finish. Closing the door triggers the next processing stage; it does not mean every payment has already settled.
Check the basket
Review the available transaction record or receipt. If an item or amount is wrong, contact the operator using the support details displayed on the machine.
Shopping duration varies with browsing, basket size, connectivity and processing. A short demonstration is not a guaranteed checkout time for every session.
02 | MULTI-ITEM RECOGNITION
Can AI vending machines recognize multiple items at once?
Vision-based vending can support several products in one shopping session. That does not guarantee that every combination of simultaneous hand movements, overlapping packages or look-alike items will be recognized correctly. Validate the actual products and picking patterns on the intended WEIMI configuration.
One basket, several products
Test different products together, repeated units of the same SKU, and taking an item before putting it back. Compare the final charged quantities with what actually left the cabinet.
Several items in one hand
Ask for a demonstration with the intended packaging. A successful single-item test does not establish performance when labels are hidden, products overlap or several items move together.
Record missed items, extra items, incorrect quantities, unresolved sessions and manual corrections separately. An accuracy percentage is only useful when its test set, measurement unit and operating conditions are stated.
03 | PRODUCT SETUP
Register products before putting them on sale
The product library connects visual packaging to a SKU and selling price. Follow the current WEIMI onboarding instructions for the required images and approval steps; image requirements can depend on the product and software version.
- Use the actual packaging: include the sizes, flavors and label versions you plan to stock.
- Check the product record: verify the SKU, price and enabled status before a paid test.
- Validate placement: confirm spacing, camera visibility and the approved layout. Open shelves do not mean every position or stack is suitable.
- Retest changes: new packaging, a changed shelf arrangement or an added product can change recognition conditions.
For refrigerated goods, follow product storage requirements and verify the cabinet's configured operating range. Visual recognition does not establish food safety or shelf life.
04 | DAILY OPERATION
Reconcile the dashboard with the cabinet
Remote records support replenishment and incident review, but they do not replace every physical check. Confirm which sales, inventory and alert functions are enabled in your software package and how updates behave during a connection interruption.
Before replenishment
Review product sales, stock records and unresolved transactions. Prepare the correct SKUs and packaging versions; inspect temperature and expiry conditions where relevant.
After replenishment
Follow the authorized refill workflow, confirm the cabinet count against the recorded inventory and run a sample purchase after meaningful product or layout changes.
Keep cameras and door areas unobstructed, check closing and locking behavior, and assign responsibility for refunds and service. The operating savings depend on the route and service workload; they are not automatic.
05 | ACCEPTANCE CHECKS
What to verify in a WEIMI demonstration
Use your proposed products and request the result of each test, including exceptions. This is an acceptance checklist, not a claim that every configuration has the same features.
| Test | What to compare | Evidence to retain |
|---|---|---|
| Mixed basket | Actual SKUs and quantities versus the final transaction | Itemized record and observed basket |
| Take and return | Items left in the cabinet versus items charged | Final quantities and exception outcome |
| Similar packaging | Flavors, sizes and near-identical labels | Correct SKU and price for each sample |
| Payment exception | Declined access, interrupted processing and incorrect charge handling | Customer message, operator procedure and refund path |
| Refill or layout change | Physical count versus recorded inventory after the approved workflow | Reconciled stock and sample transaction |
Check the current WEIMI AI vending machine configuration and request written confirmation of supported payments, product onboarding, connectivity requirements and after-sales responsibilities.
06 | PRACTICAL QUESTIONS
WEIMI operation questions
Can I put a registered product anywhere?
Use the approved shelf layout and keep products visible to the recognition system. Test placement changes; registration alone does not prove that every position, stack or orientation will work.
Is preauthorization the same as the final charge?
No. Where the payment integration uses preauthorization, it reserves an amount before the final basket is processed. The final charge and release of an unused hold depend on the payment provider and issuer. Check the deployed configuration and customer instructions.
Does computer vision remove the need for all sensors?
No. Item recognition and cabinet control are different functions. A vending fridge still needs the controls appropriate to its design, such as door and refrigeration controls. Confirm the actual hardware specification.
How should I assess recognition accuracy?
Use representative products, basket combinations and return actions. Compare each final record with the observed basket and document errors and manual intervention. Ask how the supplier defines and measures its quoted accuracy.
