This is how we do it. We initially were encouraging all ordering to be done through the QR code (we're a board game cafe, so table turn times are much lower so tables aren't checked on as often) but found our staff to be too relient on them and obviously a lot of upselling was lost. So now we take orders on the tablets, but folks can also scan in and add to the same order- it goes on the same check (this has only been the case for a few weeks) which is a huge help for us.
