The supermarket scanner might not be able to read QR codes; most supermarkets use UPC and similar 1 dimensional bar codes. You can encode any text you want into a QR code and save it as a PNG with the qrencode package. If you want other barcode formats, the zint package handles almost all of them, including QR. You can display the QR code in a terminal with the qrterminal package -- no X11 or Wayland required. If you want an X11 program to create and display QR codes, the qreator package does all of that. -dsr-
