I don’t have a barcode
Would you like to have a barcode ? If yes please let me know what you would want to do with your barcode ? If you are trying to setup Alfred then,fear not, no barcode is required, just two devices, one set as viewer and one as camera and login to both with the same gmail.com account. But make sure both devices have internet access be it via WiFi or mobile data.
yes please i have internet
Delete your email from your post before you get flooded with spam emails. You do not need a barcode for Alfred
