Clinic Query QR Code Board, WF-K3399, AndroidSBC, Los Angeles

TL;DR: Clinic Query QR Code Board

AndroidSBC field desk: query rollout map updated across hospitals, bank branches, government halls, malls and airports serving Los Angeles, United States. 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 Los Angeles and United States 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 Los Angeles integrators. Purchasing runs through the Shenzhen export desk, so Los Angeles buyers deal with the manufacturing entity rather than a trading layer.

WF-K3399 Technical Specifications

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 States 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 States Buyers

Sourcing a self-service query terminal board for United States is not only a chip question. A Los Angeles 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.

Finally, the arrival path shapes the plan. Hardware destined for Los Angeles clears through Port of Los Angeles, so the FCC / UL paperwork and the FCC Part 15 and FCC ID for radio modules, plus UL or ETL safety listing route used in United States need to travel with the carton, not follow it. For United States buyers the effect is that a 140000-unit order for Los Angeles repeats identically the 3rd time it is placed, down to the firmware revision.

Competitive Comparison: WF-K3399 vs Competing Self-Service Query Terminal Android Boards

What separates the WF-K board from competing query boards in Los Angeles is less the processor row than the peripheral and reliability rows underneath it.

• 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

Self-service query terminals are moving from a specialist niche into standard public infrastructure, and United States is part of that shift. Demand for the dual-screen HD query terminal with mirrored display is being pulled by service halls that want to shorten front-desk queues and by operators in Los Angeles who need the same answer available outside staffed hours.

• 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-K6180 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-K6180 and WF-K5270 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-K5270 over boards that re-spin silicon between lots.

For Los Angeles the opportunity sits in service coverage: operators in United States are adding information points faster than they are adding staff, and that gap is what the query terminal fills.

Partner Success Story: Nordweg Innbyggertorg (municipal citizen service operator)

A Nordweg Innbyggertorg deployment in the Nordic public service segment illustrates how the WF-K query board family supports Los Angeles integrators. Nordweg Innbyggertorg deployed 140000 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 FCC / UL conformity, all bundled into the Shenzhen source-factory shipment.

In the words of Nordweg Innbyggertorg Programme Director for Nordic Public Service: Nordweg Innbyggertorg replaced counter-side lookup binders with the WF-K compact board, and 140000 units went into Los Angeles service points without any change to the existing counter furniture.

Field Report: dual-screen HD directory query rollout at a shopping mall

BAOLONG, Shenzhen, September 22, 2026 - Cong Yu, AndroidSBC field desk.

Filed by Cong Yu, AndroidSBC field desk, BAOLONG, Shenzhen. US hospital networks and bank branch estates usually refresh self-service query terminals site by site, so boards arrive with a fixed screen count and mounting pattern per branch.

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 Los Angeles.
• 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-K8800 runs tax, social security and real estate information lookup, with printing available on the same board.
• Shopping mall directories: the WF-K8801 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-K3600 has to stay readable under strong ambient light.
• Retail and pharmacy price or product lookup: compact stations where the WF-K3601 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 Los Angeles: 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 Los Angeles Buyers

Three partnership tracks serve the United States market, and Los Angeles integrators can move between them as their own capability and volume change.

• 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.

AndroidSBC reviews Los Angeles track selection annually with each partner, because United States market conditions and the partner own capability both move faster than a fixed reseller contract assumes.

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 covered by the standard WF-K driver SDK, which means the Los Angeles integrator configures it rather than ports it.

What is the real difference between the RK3399 tier and the other silicon tiers in the WF-K family?

Answer: Practically, the RK3399 tier is chosen when the United States use case matches its video and AI envelope. The interface contract is identical across the family, so the decision is about workload rather than about connectors or drivers.

Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for United States?

Answer: Yes, and the paperwork is treated as part of the product rather than an add-on. For United States orders the CE, FCC, RoHS and REACH set is prepared alongside the production lot bound for Los Angeles.

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. Los Angeles buyers can start small, then scale once United States 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. AndroidSBC handles AOSP customisation, kiosk-mode lockdown and Linux images for the WF-K family, with the resulting build validated on the same rig used for United States shipments to Los Angeles.

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 Los Angeles estate is live and United States 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 States fulfilment centres on behalf of Los Angeles 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. Los Angeles partners report against the lot number and AndroidSBC matches it to the rig log.
