- Number of items in receipt and number of already controlled items (so far) are shown in header on left / right hand side of the screen
- Items may be controlled by scanning, or by being chosen via a 'PLU list' button, or by pressing an 'OK' button.
- Shopping bags are listed last in the top section, along with other items with an 'OK' button.
- Controlled items that trigger deviation (not scanned by customer) are marked. This information may / should lead to staff scanning all customer's items, in case of possible more deviations in customer's basket.
- Controlled items that trigger deviation by accident, e.g. was unintentionally scanned twice by staff, may be deleted by clicking the item line.
- When control is confirmed by staff it will either pass or show a deviation message, where all items that triggered deviation are listed. These items will be added to receipt and paid by customer when deviation is confirmed by staff.
