When we are selling products only please tell the customer to skip the Tip option on the credit card terminal. If they insist on giving you a tip please do the following on the screen when you press the Ring Out to make sure you get the tip.
When you press the Ring Out you will see the following screen. At the bottom section you need to search for your name
(step 1), click on your name
(step 2) and finally make sure all of the change is tip (step 3).
This is the only way you will get the tip on the Branch card.
