TL;DR: Fingerprint Payment Cashier Board
AndroidSBC OEM partnership announcement extending WF-S board availability serving international market, United States. The WF-S3504 self-service checkout Android motherboard spans the industrial fanless self-checkout SBC and eight sister models (WF-S3500 through WF-A1303), all built on the RK3568 quad-core ARM Cortex-A55 2.0GHz 64-bit SoC with the Mali-G52 2EE GPU and 1 TOPS NPU, HDMI 4K + dual LVDS, and Android 13 / Linux firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-S family from the Longgang source factory in Shenzhen to international market and United States importers who run self-checkout, POS terminal, kiosk, dual-screen cashier, smart retail, and unmanned-store programs.
