Customers reading the total upside-down from your screen is not a great experience. A paired customer screen shows them their side of the transaction.
Pair with a Code
The customer screen pairs to the counter with a code, so setting one up does not need a technician.
They See What You Ring Up
Items, prices and the running total appear as they are added, which catches a mistake while it is still easy to fix.
Confirm and Sign
A confirmation checklist and signature capture on the customer screen give you a record they agreed at the counter.
