The self-service document processing machine is a self-service device for residence permit services, enabling self-service document production and re-endorsement. The entire process requires no human intervention, providing 24/7 unattended self-service. The product utilizes our company's industry-first "erasable and rewritable document card based on surface information" overall technology solution, integrating document printing and erasing technologies to complete document production and chip information writing in one stop. Users can quickly complete the process through an intelligent interactive interface, intelligent voice prompts, and animated visuals. Compared to the centralized document production and hierarchical distribution at manual windows, the self-service terminal allows for document production and retrieval anytime, greatly improving service efficiency and eliminating the impact of weekday commutes, providing 24/7 self-service.
