Query Terminal Voice Board for Hospital Information Point, WF-K3399, AndroidSBC, Liverpool
TL;DR: Query Terminal Voice Board for Hospital Information Point
AndroidSBC software desk: Android 15 baseline and staged OTA channel published for the WF-K family serving Liverpool, United Kingdom. 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 Liverpool and United Kingdom 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
Wanlin Manufacturing Group builds boards and nothing else, which is why the WF-K query terminal line is sold factory direct through AndroidSBC. Twelve models cover hospital, bank, government, retail, transport and outdoor query duty, and each one leaves the Longgang line in Shenzhen with the same peripheral driver bundle for Liverpool integrators. Purchasing runs through the Shenzhen export desk, so Liverpool buyers deal with the manufacturing entity rather than a trading layer.

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 United Kingdom 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 United Kingdom Buyers
Sourcing a self-service query terminal board for United Kingdom is not only a chip question. A Liverpool integrator has to align the touch stack, the printer and scanner drivers, the enclosure cut-outs and the compliance file set before a single unit reaches the field.
Compliance and logistics compound each other. Boards for Liverpool move through Port of Felix, and any mismatch between the UKCA / Ofcom documents and the UKCA marking with the Ofcom radio interface registration route applied in United Kingdom surfaces at exactly the wrong moment. For United Kingdom buyers the effect is that a 75700-unit order for Liverpool repeats identically the 6th time it is placed, down to the firmware revision.
Competitive Comparison: WF-K3399 vs Competing Self-Service Query Terminal Android Boards
A Liverpool buyer comparing query boards for United Kingdom 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 self-service query market sits inside the broader kiosk expansion, but it behaves differently: replacement cycles are longer and the peripheral stack matters more. United Kingdom buyers in Liverpool therefore tend to standardise on one board family rather than mixing vendors per site.
- 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-K3600 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-K3600 and WF-K3601 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-K3601 over boards that re-spin silicon between lots.
In United Kingdom the winners so far are the integrators who standardised early on one query board family, which is the pattern AndroidSBC sees across Liverpool accounts.
Partner Success Story: Deccan Info Technologies (retail and telecom self-service vendor)
A Deccan Info Technologies deployment in the India retail and telecom segment illustrates how the WF-K query board family supports Liverpool integrators. Deccan Info Technologies installed 75700 query kiosks across retail and telecom service points.
- OEM relationship: AndroidSBC private-label SKU shipped with Deccan Info Technologies 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 UKCA / Ofcom conformity, all bundled into the Shenzhen source-factory shipment.
Deccan Info Technologies Head of Delivery for India Retail and Telecom noted: Deccan Info Technologies needed high volume at a short lead time, and 75700 WF-K entry boards reached Liverpool on schedule with the touch and printer stack already validated.
Field Report: dual-screen HD directory query rollout at a shopping mall
BAOLONG, Shenzhen, September 22, 2026 - Hao Ran, AndroidSBC field desk. The WF-K3399 lot was soak-tested with the hall display and the touch panel running from one board, the configuration most United Kingdom projects specify. The WF-K3399 self-service query terminal Android motherboard order for Liverpool, United Kingdom cleared the burn-in station on schedule and is en route via the Felixstowe - Shanghai lane.

For United Kingdom integrators, the UKCA marking with the Ofcom radio interface registration paperwork is bundled.
Filed by Hao Ran, AndroidSBC field desk, BAOLONG, Shenzhen. UK council service points and clinics ask for query terminals with silent touch feedback plus a readable information display for queuing visitors.
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 Liverpool.
- 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 Liverpool: 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 Liverpool Buyers
For United Kingdom buyers the working models are three: a distribution track, an integration track and a private-label track, all open to Liverpool 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 United Kingdom order, Liverpool 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, and it is qualified on the same production line as the rest of the family. The dual-screen HD query terminal with mirrored display runs on the WF-K baseline image that United Kingdom buyers receive, so there is no separate integration project.
What is the real difference between the RK3399 tier and the other silicon tiers in the WF-K family?
Answer: The RK3399 tier sits at a specific point on the price-versus-headroom curve. Below it the boards suit single-screen information lookup; above it they support dual-screen independent display and heavier video work, and AndroidSBC documents that mapping for Liverpool buyers.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for United Kingdom?
Answer: Yes. Compliance files for United Kingdom are bundled into the source-factory shipment to Liverpool, and AndroidSBC provides the underlying test reports as well as the certificates on request.
What are the MOQ and lead time for a first order of the WF-K self-service query terminal family?
Answer: The first order MOQ on the WF-K family is set for pilot runs rather than container loads. Liverpool buyers can start small, then scale once United Kingdom field data is in hand, with 15-30 day bulk lead times.
Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-K family?
Answer: Yes. Custom ROM work on the WF-K family is scoped per Liverpool project rather than sold as a generic service, which keeps the United Kingdom deliverable tied to a specific deployment.
How are software updates and long-term support handled on the WF-K family?
Answer: Software updates on the WF-K family are staged rather than immediate, with rollback available at each step, which matters when a Liverpool estate is live and United Kingdom sites cannot tolerate an unplanned outage.
Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-K family?
Answer: Yes. AndroidSBC regularly ships the WF-K family into United Kingdom fulfilment centres on behalf of Liverpool sellers, handling the labelling and carton marking at the source factory.
How are RMA and DOA replacements handled on the WF-K self-service query terminal family?
Answer: RMA and DOA units are handled against the production lot, since every WF-K board is logged against its firmware revision and burn-in result before it leaves Shenzhen. Liverpool partners report against the lot number and AndroidSBC matches it to the rig log.
