A dual-screen POS machine is an electronic payment device that combines the payment functions of a traditional POS machine with modern dual-screen display technology. By adding a secondary screen (facing the customer) to the main screen (usually for the cashier), it enhances the transparency and interactivity of the payment process.
This design not only optimizes the customer's payment experience but also improves communication efficiency between merchants and customers, making it an indispensable payment tool in modern retail, catering, and other industries.
