A customer-facing screen is a screen that faces customers at the point of sale. Most large retailers use them. Often in a three-in-one unit like this one.
Using them while you are ringing up the transaction, your customer can actively follow what you are doing.
Here are some advantages that it gives you
-It helps build customer trust, as the customer can see what you have put in while you are doing it.
-It speeds up the queue as the customer will have many of their queries answered on the screen, eg the price of a product or whether a discount was applied.
-It gives you an aura of professionalism.
