Our task was to create to our dedicated partner (K9-Sport Kft.) a mobile application that uses various functions of Business Central on a phone environment, including: Warehouse/Inventory – Picking/Movements/Storage. With the application and the new extension for Business Central, we have also solved the possibility of assigning different tasks to users, so it is not necessary to purchase different licenses for Business Central. The system uses the phone's camera to read a QR code and also barcode. The year of the development of this project was 2022. The challenges were here to create an interface between Business Central and our Blazor web app with the integration of the Javascript QR and barcode reader.
