We need a simple software for stock management. We have different type of components and for each type of components several traceability Number. Each time we took a component from our stock, we need to write by hand: - Components number - Components name - Components traceability Number - Quantity added / removed We would like to have software that allows us to, using a barcode reader, automatically fill the: - Components number - Components name - Components traceability Number So we will only have to enter manually: - Quantity added / removed 1) The Software will allow us to fill a data base with the informations of our different components (code, name, traceability Number, ...) with a corresponding barcode. 2) The software will be run on a Raspberry Pi 3 with a touchscreen 3) The software should recognize a barcode reader and the barcode Writing font. 4) The software must have a function that allows us to export all the data of chosen components into Excel sheet. 5) The software should automatically add the date of stock transfer (in or out) The software should have a home page with links to: - Components data base (where we handle the components list, traceability Number, ...) - Stock (where we can see the remaining stock + extract the data into Excel file) - Transfer (were, using the barcode reader, we can add or remove components quantity)
