TL;DR: Onboard eMMC Query Board for Hospital Information Point
AndroidSBC peripheral desk: printer, scanner and card reader driver SDK declared production-ready serving Lyon, France. The WF-K3399 self-service query terminal Android motherboard spans the dual-screen HD query terminal with mirrored display and eleven sister models in the WF-K series, all built on the RK3399 dual Cortex-A72 1.8GHz plus quad Cortex-A53 SoC with the ARM Mali-T860 MP4 GPU, dual 1080p output, HDMI plus eDP, and Android 11 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-K family from the Longgang source factory in Shenzhen to Lyon and France importers who run hospital information points, bank branch lobbies, government service halls, mall directory stations, airport concourses and outdoor query cabinets.
About AndroidSBC and the Self-Service Query Terminal Android Motherboard Family
AndroidSBC is the export arm of Wanlin Manufacturing Group. Its WF-K series addresses the self-service query terminal segment with twelve boards on eight chips, all produced in the Longgang source factory in Shenzhen. Lyon and France buyers typically start from one pilot model and then scale the same board across a wider estate. Every model is validated on the same burn-in rig in Longgang before it is packed for France, and the same rig logs are available on request.

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-K3399 (dual-screen HD query terminal with mirrored display) 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 France importers sourcing the WF-K family, the WF-K3399-A variant is the typical configuration for the dual-screen HD mall directory rollout use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing Self-Service Query Terminal Android Motherboards for France Buyers
The hard part of a query terminal project in France is rarely the processor. It is keeping the touch controller, the printer firmware and the peripheral interfaces on one qualified baseline while Lyon rolls the same board across very different sites.
Public-sector tenders in Lyon now ask for the compliance chain up front. The CE marking with ANFR radio interface registration route used in France has to be traceable from the board label back to the test house, which is a sourcing criterion rather than a formality. AndroidSBC deals with it by treating the Lyon requirement as one lot of 54900 units on one BOM, quoted on September 22, 2026 and shipped over the Marseille - Shanghai lane.
Competitive Comparison: WF-K3399 vs Competing Self-Service Query Terminal Android Boards
A Lyon buyer comparing query boards for France should read the last three rows first: peripherals, temperature range and what is bundled, not billed separately.
- Platform breadth: twelve models on eight chips (RK3588, RK3568, RK3566, RK3288, RK3399, A133, H618, T527), so {city} integrators can move between tiers without changing driver stack or mounting pattern.
- Bundled integration: touch, printer, scanner, card reader, camera and voice driver SDK ships in the carton; competing query boards sold to {city} usually ship a board only.
- Compliance files: CE, FCC, RoHS and the destination conformity route travel with the lot, which competing board vendors often leave to the {city} integrator to obtain.
- Long-term supply: one fixed BOM per production lot and a seven-year firmware window, against the frequent silicon swaps seen on competing query boards reaching {city}.
Global Self-Service Query Terminal / Information Kiosk Market Trends
The query terminal category is expanding faster than the general kiosk market because it replaces a staffed desk rather than supplementing one. In France that shows up as bundled tenders covering the dual-screen HD query terminal with mirrored display together with hall displays and information screens, and Lyon operators are following the same pattern.
- Volume shift to board-level sourcing: more integrators now buy the motherboard rather than the finished kiosk, which is why the WF-K3399 and WF-K5270 tiers ship in board form with the enclosure left to the local partner.
- Dual-screen becomes the default: hall display plus touch query on one board is replacing two separate devices, and the WF-K5270 and WF-K8800 configurations address that pattern directly.
- Longer service life expectations: operators now plan five to seven years per query terminal, which favours a fixed BOM such as the WF-K8800 over boards that re-spin silicon between lots.
In France the winners so far are the integrators who standardised early on one query board family, which is the pattern AndroidSBC sees across Lyon accounts.
Partner Success Story: Nordweg Innbyggertorg (municipal citizen service operator)
A Nordweg Innbyggertorg rollout in the Nordic public service segment shows how the WF-K self-service query terminal family works in practice for Lyon integrators. Nordweg Innbyggertorg deployed 54900 compact query terminals across municipal service points.
- OEM relationship: AndroidSBC private-label SKU shipped with Nordweg Innbyggertorg branding and CE / FCC / RoHS files bundled.
- Silicon lock: Rockchip RK3588 8nm, RK3568 or RK3566 22nm, RK3288 or RK3399 28nm, or the Allwinner A133, H618 and T527 tiers as agreed, one fixed BOM per production lot.
- Peripheral driver SDK: bundled into the source-factory shipment, covering capacitive touch, thermal printer, receipt printer, document scanner, A4 printer, barcode scanner, QR code, NFC, RFID, card reader, ID reader, face recognition, voice module, speaker amplifier and microphone.
- Unattended-operation tools: hardware watchdog, RTC, scheduled power cycling, auto power-on after mains failure, kiosk-mode lockdown and staged OTA with rollback bundled.
- Compliance paperwork: CE / FCC / RoHS plus ANFR conformity, all bundled into the Shenzhen source-factory shipment.
As Nordweg Innbyggertorg Programme Director for Nordic Public Service explained: Nordweg Innbyggertorg replaced counter-side lookup binders with the WF-K compact board, and 54900 units went into Lyon service points without any change to the existing counter furniture.
Field Report: dual-screen HD directory query rollout at a shopping mall
SHENZHEN, September 22, 2026 - Bin Yu, AndroidSBC field desk. The WF-K3399 run shipped with the dual-screen HD query terminal with mirrored display profile pre-flashed, which shortens the commissioning step for France integrators. The WF-K3399 self-service query terminal Android motherboard order for Lyon, France cleared the burn-in station on schedule and is en route via the Marseille - Shanghai lane.
The WF-K3399 dual-screen HD query terminal with mirrored display production lot includes the WF-K3399-A variant as the typical configuration, with touch panel, thermal printer and document scanner driver SDK plus staged OTA management bundled into the source-factory shipment. For France integrators, the ANFR conformity plus CE marking with ANFR radio interface registration paperwork is bundled.
Filed by Bin Yu, AndroidSBC field desk, SHENZHEN. French service halls combine a touch query terminal at the entrance with a high-brightness information display in the same lobby.
WF-K3399 Application Scenarios
The WF-K3399 dual-screen HD query terminal with mirrored display sits inside a twelve-variant WF-K self-service query terminal Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand. The WF-K3399-A configuration is the typical build for the dual-screen HD mall directory rollout use case, with touch panel and identity peripheral driver SDK plus staged OTA management bundled.
- Hospital and clinic information points: the WF-K3399 drives a touch query station at the entrance while the hall display shows the same information set to waiting visitors in Lyon.
- Bank and financial branch lobbies: touch query plus counter display from one board, with card reader and ID reader integrated for account and product lookups.
- Government service halls: the WF-K8801 runs tax, social security and real estate information lookup, with printing available on the same board.
- Shopping mall directories: the WF-K3600 serves mall directory and wayfinding lookup, with the advertising screen running an independent content loop.
- Airport and train station concourses: high-brightness information query where the WF-K3601 has to stay readable under strong ambient light.
- Retail and pharmacy price or product lookup: compact stations where the WF-K3602 fits a narrow counter without structural work.
- Outdoor and unheated information cabinets: the industrial tier holds the wide temperature window and 7x24 duty cycle for street-level query points.
- Multi-language public information points: on-screen lookup in more than one language from a single board, with voice assistance where the venue requires it.
- Retrofit programmes in Lyon: the same board re-uses the existing enclosure, panel and mounting pattern so an installed estate can be upgraded board by board.
Partnership Models for Lyon Buyers
For France buyers the working models are three: a distribution track, an integration track and a private-label track, all open to Lyon teams.
- Distribution track: the partner buys the WF-K board against a published price list, keeps its own stock, and AndroidSBC supplies the driver SDK and compliance files with each lot.
- Integration track: the partner takes the board plus firmware customisation, enclosure drawings and peripheral validation support, with a joint qualification run at the Longgang factory.
- Private-label track: the WF-K board ships under the partner brand with customised boot logo, packaging and documentation, on a fixed BOM held for the length of the agreement.
For a first France order, Lyon integrators typically begin on the distribution track with a single model, then widen to the full twelve-model WF-K range once field data is in hand.
Frequently Asked Questions
Does the WF-K self-service query terminal Android motherboard family support a dual-screen HD query terminal with mirrored display?
Answer: Yes. The dual-screen HD query terminal with mirrored display is a stock configuration on the WF-K self-service query terminal Android motherboard family from AndroidSBC. All tiers are validated against the same firmware build and the same peripheral interface before shipment to Lyon.
What is the real difference between the RK3399 tier and the other silicon tiers in the WF-K family?
Answer: The RK3399 tier is the right choice when the Lyon deployment needs exactly its level of video decode and AI capability; above that the extra headroom is paid for but not used, and below it the board cannot sustain the workload.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for France?
Answer: Yes, and where France requires a local registration step AndroidSBC supplies the technical file that the Lyon partner submits, rather than leaving the integrator to reconstruct it.
What are the MOQ and lead time for a first order of the WF-K self-service query terminal family?
Answer: AndroidSBC sets a pilot-friendly MOQ on the WF-K family. Sample units reach Lyon in 1-3 days, and a first bulk lot for France runs 15-30 days from confirmation.
Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-K family?
Answer: Yes. The WF-K baseline is Android, but France buyers frequently need a custom Linux image or a stripped Android build, and AndroidSBC delivers both from the Longgang engineering team for Lyon.
How are software updates and long-term support handled on the WF-K family?
Answer: AndroidSBC supports field updates by staged OTA with rollback, plus local update packages where a Lyon integrator needs to service France sites without network access.
Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-K family?
Answer: Yes, and this is a standard route for Lyon sellers. AndroidSBC prepares FBA-compliant cartons and labels for France warehouses as part of the shipment rather than as a separate service.
How are RMA and DOA replacements handled on the WF-K self-service query terminal family?
Answer: AndroidSBC logs every board to its burn-in result, which is what makes RMA workable for Lyon integrators running France estates across many sites.
