Local Integration (External Device)

Suitable for scenarios where no application development on the POS terminal is needed. In this case, the Vendor Machine communicates directly with the PAYWizard on the terminal. The communication between the POS terminal and the Vendor Machine supports serial port, MDB (Multi-Drop Bus), Socket, and other protocols. Apart from the MDB communication method, all data transmission and reception shall be carried out in accordance with the protocol document: Core Protocol.
