System Context
The UI looks like a normal costumer app and can be used intuitively. All applications have a responsive design: The UI adapts the screen size of the appropriate platform on the smartphone or tablet device and can therefore be used on all systems without screen adaptions.
Internally, the Self-Scanning solution utilizes the Self-Scanning services of the GK/Retail Business Suite. The GK/Retail OmniPOS service also provides the central functions and web services for the Self-Scanning Client. A layer between the Self-Scanning Client and the mobile operating system secures the communication with the hardware device.
To use Self-Scanning, customers have to sign up to a customer program with a customer card. Therefore, it is absolutely necessary to have a customer database to assign the customer number to an open shopping basket.
The customer can only connect their customer card/customer number to one store at a time. However, customer-specific deviations from these rules are possible. Once the customer is in possession of a customer card from a retailer, they can use their customer card in the retailer's stores in other locations without needing to sign up for each individual store again.
- Typically, customers scan the barcode of an item. If items do not have a barcode (e.g. bread), there must be a barcode that can be scanned in the shelf.
- The customer usually weighs fruits or vegetables on a scale in the appropriate shop area. The scale receipt must contain a barcode for the customer to scan.
