Customer facing display for TakePOS

I’m evaluating using Dolibarr to run a seasonal business. Our typical customer might purchase 15 to 20 items at a time. We have been using Copper from NCH software and would prefer something with more power and integration. One feature that I can’t find a solution for is an option for the customer to see what gets added to their purchase as we ring up the transaction. Similar to what you see at Walmart. I’ve found this really helps the customer have confidence that they are being charged the correct amount.

Is there a method to show the customer what gets added to the sale as it gets added using a second display?
