TL;DR: Government Hall Inquiry Terminal Board
AndroidSBC field desk: citizen service rollout map updated across tax, social security, immigration and public security halls serving international market, United States. The WF-S3399 government service kiosk Android motherboard spans the dual-screen high definition service terminal and eleven sister models in the WF-S series, all built on the RK3399 dual Cortex-A72 1.8GHz plus quad Cortex-A53 SoC with the ARM Mali-T860 MP4 GPU, dual 4K output, HDMI plus eDP, and Android 11 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 citizen service hall, tax and social security counter, certificate printing, identity verification, public information display and outdoor smart city programmes.
WF-S3399 Technical Specifications
| Parameter | AndroidSBC WF-S3399 (dual-screen high definition service terminal) | Industry Average |
|---|---|---|
| Processor | RK3399 dual Cortex-A72 1.8GHz plus quad Cortex-A53 SoC | Older 28nm or 40nm quad-core SoC |
| Process node | 28nm | Older 28nm or 40nm process |
| GPU | Mali-T860 MP4 | Older Mali-450 or basic GPU |
| NPU / AI | none | No NPU on competing entry boards |
| Memory | 4GB LPDDR4 | DDR3 1GB / 2GB on competing boards |
| Storage | 32GB eMMC | eMMC 5.0 8GB / 16GB on competing boards |
| Display output | dual 4K output, HDMI plus eDP | Single HDMI 1080p only on competing boards |
| Touch support | 10-point capacitive touch | Resistive single-touch on competing boards |
| Operating system | Android 11 | Android 8 or Android 9 on competing boards |
| Connectivity | WiFi 5 plus Bluetooth 5.0 plus Gigabit Ethernet | WiFi 4 plus 10/100M Ethernet on competing boards |
| Payment peripherals | QR code scanner, NFC, barcode scanner, thermal printer, cash drawer | No bundled payment-peripheral driver SDK on competing boards |
| Operating temperature | 0C to 50C | 0C to 40C on competing boards |
All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-S3399 (dual-screen high definition service terminal) maintains its 4K HDMI output plus capacitive touch sampling while running the burn-in test loop, a configuration that competing single-platform boards cannot sustain at 60fps. For United States importers sourcing the WF-S family, the WF-S3399-A variant is the typical configuration for the high resolution citizen information terminal use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing Government Service Kiosk Android Motherboards for United States Buyers
The first obstacle for United States buyers is specification drift. A datasheet says RK3588, the delivered lot carries a different memory vendor, and the identity reader driver that passed the pilot fails on the production image six months later.
On cost the answer is a tier ladder, not a discount. AndroidSBC maps the international market estate by job: enquiry points on the entry tiers, dual-screen counters on the mid tiers, AI identity verification on the RK3588 tier, so aa United States programme does not pay flagship pricing for a notice screen. On the international market - Shanghai lane, 138000 boards are committed for international market and United States as of September 20, 2026; AndroidSBC counts this as the 3rd release window on the family.
WF-S3399 Application Scenarios
The WF-S3399 dual-screen high definition service terminal sits inside a twelve-variant WF-S government service kiosk Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand. The WF-S3399-A configuration is the typical build for the high resolution citizen information terminal use case, with identity peripheral driver SDK and staged OTA management bundled.
- Citizen service hall enquiry and queue points: WF-S3399 plus WF-S8800 form the hall entry ladder, with independent dual display output and 4K HDMI.
- Tax, social security and housing fund counters: WF-S8800 plus WF-S8801 are the usual pairing where certificate printing and ID verification run on the same board.
- Immigration and public security checkpoints: WF-S8801 is the dedicated secure identity SKU, with secure boot, trusted execution and an audit trail that survives a power cycle.
- AI identity verification and face recognition terminals: WF-S3600 plus WF-S3601 cover the vision and verification workload on the device.
- Community and neighbourhood service desks: the compact WF-S3399 and the entry-tier sister SKUs serve walk-in enquiry where counter space is limited.
- Outdoor and semi-outdoor municipal cabinets: the industrial T527 sister SKU takes the 24-hour unattended points that see a full seasonal temperature range in international market.
- Hall notice and announcement networks: the H618 and A133 sister SKUs drive continuous-play public information screens across a international market building estate.
- Document scanning and form filling terminals: WF-S3601 plus WF-S8800 pair the scanner and the signature pad on one board for the international market administration.
- Legacy estate refresh programmes: the RK3288 and RK3399 sister SKUs match the mechanical and electrical footprint of existing international market hall terminals, so a refresh does not become a redesign.
Partnership Models for international market Buyers
AndroidSBC publishes the three tracks it runs for international market and United States because public sector procurement usually dictates which one applies before the technical discussion starts.
- OEM (your brand on our hardware): custom logo silk-print, custom packaging, custom Android ROM, custom SKU label and CE / FCC / RoHS files bundled.
- ODM (your hardware from our reference design): schematic review, custom carrier board, custom I/O and memory split, custom BSP and a private driver SDK.
- Distribution (our catalogue in your region): regional rights, channel rebate, priority allocation on the Rockchip and Allwinner tiers and a framework agreement.
One production line in Longgang serves all three tracks, so a international market partner who starts on the distribution track and later commissions an ODM design stays on the same United States supply chain.
Does the WF-S government service kiosk Android motherboard family support a dual-screen high definition service terminal?
Answer: Yes. The dual-screen high definition service terminal is covered by the standard WF-S driver SDK, which means the international market integrator configures it rather than ports it.
What is the real difference between the RK3399 tier and the other silicon tiers in the WF-S family?
Answer: The RK3399 choice is mostly about workload. Notice screens and enquiry points do not need it, dual-screen counters usually do, and AI identity verification terminals need the RK3588 tier specifically. AndroidSBC publishes the mapping and international market integrators can sanity-check it against their own tender.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for United States?
Answer: Yes, and it is produced by the same team that builds the board. AndroidSBC issues FCC Part 15 and FCC ID for radio modules, plus UL or ETL safety listing documentation and the FCC / UL file for United States before the international market consignment is palletised.
What are the MOQ and lead time for a first order of the WF-S government service kiosk Android motherboard family?
Answer: The MOQ depends on the track. Samples ship from one piece in 1-3 days, OEM branding starts at 100 pieces, and ODM work starts at 500 pieces, with 15-30 day mass production for international market and United States.
Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-S family?
Answer: Yes. For international market and United States the software deliverable can be as small as a boot animation or as large as a maintained AOSP fork, and both are covered by the same support window as the standard WF-S image.
How are software updates and long-term support handled on the WF-S family?
Answer: AndroidSBC commits to a seven-year firmware update window on the WF-S family, delivered as staged OTA with rollback. United States estates can hold a revision while the international market integrator validates it.
Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-S family?
Answer: Yes. AndroidSBC supports FBA and 3PL consolidation delivery for the WF-S family, with the Port of international market routing and the export documentation handled by the export desk.
How are RMA and DOA replacements handled on the WF-S government service kiosk Android motherboard family?
Answer: DOA boards are replaced on the next shipment and RMA units are repaired or replaced against the board revision record, which AndroidSBC keeps versioned for every international market and United States lot.
