Inquiry about POS Terminal Hardware with Dual Display and NFC NEW

I am developing a fixed, wall/pole-mounted POS terminal for bar counters and need a supplier to provide the core hardware. Requirements: - Compact Android mainboard (RK3568 or similar), housed in an enclosure with base approx. 15x15 cm and height approx. 30 cm. - Must support two independent, non-mirrored display outputs: one touchscreen (approx. 4-5") for staff, one display-only screen (same size) for customers. - Integration with an NFC reader/writer module near the customer-facing screen. - Powered via mains electricity and wired Ethernet only; no battery, no Wi-Fi/mobile network dependency (Wi-Fi as backup is acceptable). - Runs Android OS for our custom POS application. I plan to start with a single prototype, followed by a production run of approximately 60 units. I need a supplier who can support both low-volume prototype and small-batch production without re-engineering the hardware. Please provide information on: - Which of your boards/modules best fits this use case? - Whether dual independent display output and NFC module integration are supported out of the box. - MOQ for prototype vs. production batch of ~60 units. - CE certification status. - Estimated lead time and indicative pricing for both quantities.
