Great feature to have a QR code..
But when the customer scans the QR code from the receipt, it requires login to show the tax invoice, how to allow viewing the receipt when scanning the QR without having to login?
It was supposed to open the sale but as admin are don't have the customer login feature, so it was left behind.
I will check about this in future update and improve this to use has instead id.
Thank you dear, how long do you expect this feature to be released?
