is it possible through API to add tax line to register closing receipt? It is standard audit procedure for such information to be on closing receipt and without it I need to run a report from admin and staple to closing receipt which is simply crazy waste of time.
We're shipping QR codes on receipts soon. You'll be able to default to QR codes added to receipts, and then when presented with the receipt you will be able to scan it with the iPad's front-facing camera. We're testing it now.
