Scanning QR codes with a smartphone or a webcam
As of autumn 2022, invoices received from your swiss suppliers are normally accompanied by a QR-code containing all the information required for payment. Depending on the number of invoices you receive, it may be worth scanning the QR-code to save time and avoid input errors.
QR code readers come in a variety of models. But you can save on their purchase by using your smartphone, provided you install ad hoc software such as Barcode To PC. This technical note (french | german) tells you more about this solution.
Another solution is to use your webcam. It takes a little time getting used to, to find the right reading distance.
