Thanks to the QR code function, your terminal will be able to read these codes. For example, if you issue invoices with a QR code to your customers, they can pay them at your terminal by scanning the code from the invoice.
This is an extension of the function Sale. After selecting the function Sale, just select the QR code, a camera will turn on on the terminal, which allows you to scan the code. The amount to be paid is then displayed on the terminal screen, the rest of the transaction proceeds as a standard sale. The Variable symbol is printed on the receipt.
