It’s sometimes a matter of whatever POS is being used. Cashier needs to tell system the payment method for the sale to be completed. Currently I push the “credit card” button and the pin pad does the rest …asking the customer to put a pin (debit card) or if it’s a plain credit card it just processes and completes.
