Item Recognition by Camera

If the function is configured and a camera is connected, the Welcome screen is displayed and the customer is prompted to put an item on the scale.

The display language can be changed by pressing the language button on the top right corner of the Welcome screen.

• The customer puts the item on the scale.

Once a stable weight is detected, the POS uses the connected camera to take a picture of the item. This process takes place in the background (not visible to the customer).

The POS then sends the image to the KanduAI service. The response from the KanduAI service contains the item description (e.g. tomato) and a match rate (e.g. 80).

The POS maps the item description from KanduAI to the configured PLU (e.g. the description = "tomato" is mapped to the PLU = 1392).

The POS displays the recognized items. The results are sorted by match rate (from the highest match rate on the left to the lowest match rate on the right).

• If the item has been correctly recognized by the scale, the customer taps the item button.

  The receipt is printed and the Welcome screen is displayed again for the next item to be weighed.

• If the scale displays an incorrect item, the customer presses "Show All".

  The tableau screen for manual selection of the item is displayed.

  The customer proceeds as described in the section "Item Entry via Tableau Screen".

• If the scale could not identify the item or find a mapped PLU, an error screen is displayed.

• The tableau screen for manual selection of the item is displayed.

  The customer proceeds as described in the section "Item Entry via Tableau Screen".

Entering the Quantity of Piece Items

Certain items may be calculated by quantity rather than weight.

1. The customer enters the PLU or presses the item button and confirms this with the corresponding button.

   The Self Service Scale processes the item search.

2. If an item is found and marked as a piece item, the mask for entering the quantity is displayed.

   

3. If the customer cancels the mask, the item is voided. The mask is also canceled after a defined timeout.
4. If the customer confirms the mask with the entered quantity, receipt printing starts.

   A waiting dialog is displayed until the print process is finished.
