Some retailers mount their SuiteCommerce InStore (SCIS)tablets on swivel stands or similar accessories that can rotate the display to face the customer.
This accessory type is helpful for customers who want to review the prices and discounts shown in the cart, before beginning the payment steps. The sales associate can turn the display at the customer’s request.
You should not “mirror” the display used by the sales associate. Replicating your sales associate's display for the customer could expose information that should be kept secure and confidential.
For example, some tablets will briefly display each character of a password as it is entered.
