TL;DR: Query Terminal Fingerprint Board for Tax Service Hall
AndroidSBC software desk: Android 15 baseline and staged OTA channel published for the WF-K family serving Vilnius, Lithuania. The WF-K3600 self-service query terminal Android motherboard spans the dual-screen query terminal with independent display and eleven sister models in the WF-K series, all built on the RK3568 quad-core ARM Cortex-A55 2.0GHz 64-bit SoC with the ARM Mali-G52 2EE GPU, dual 1080p independent output, LVDS plus HDMI, 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 Vilnius and Lithuania 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 Vilnius integrators. The plant holds a standing allocation of LPDDR4X and eMMC for the WF-K line, which is how Vilnius projects keep their lead times stable across quarters.

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-K3600 (dual-screen query terminal with independent 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 Lithuania importers sourcing the WF-K family, the WF-K3600-A variant is the typical configuration for the dual-screen bank branch query rollout use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing Self-Service Query Terminal Android Motherboards for Lithuania Buyers
Sourcing a self-service query terminal board for Lithuania is not only a chip question. A Vilnius 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 Vilnius clears through Port of Hamburg, so the RRT paperwork and the CE marking with RRT radio interface notification route used in Lithuania need to travel with the carton, not follow it. For Lithuania buyers the effect is that a 91700-unit order for Vilnius repeats identically the 4th time it is placed, down to the firmware revision.
Competitive Comparison: WF-K3600 vs Competing Self-Service Query Terminal Android Boards
Against the query boards usually quoted in Lithuania, the WF-K board is positioned on integration completeness rather than on a single performance number for Vilnius.
- 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
Public-facing information lookup is now measured as a service-level question, not a hardware line item. Lithuania procurement increasingly specifies the dual-screen query terminal with independent display as part of a wider access programme, which pushes Vilnius integrators towards boards that can be re-deployed across sites.
- Volume shift to board-level sourcing: more integrators now buy the motherboard rather than the finished kiosk, which is why the WF-K3600 and WF-K3399 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-K3399 and WF-K1330 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-K1330 over boards that re-spin silicon between lots.
That trend favours board-level suppliers in Lithuania: the Vilnius buyer who can re-order the same part number two years later is the one who can keep an estate running.
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 Vilnius integrators. Nordweg Innbyggertorg deployed 91700 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 RRT conformity, all bundled into the Shenzhen source-factory shipment.
As Nordweg Innbyggertorg Programme Director for Nordic Public Service put it: Nordweg Innbyggertorg replaced counter-side lookup binders with the WF-K compact board, and 91700 units went into Vilnius service points without any change to the existing counter furniture.
Field Report: dual-screen query terminal rollout at a city bank branch network

Filed by Jin Tao, AndroidSBC field desk, YANTIAN, Shenzhen. Lithuania integrators typically request CE plus local radio interface notification for self-service query terminal board deployments.
WF-K3600 Application Scenarios
The WF-K3600 dual-screen query terminal with independent 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-K3600-A configuration is the typical build for the dual-screen bank branch query rollout use case, with touch panel and identity peripheral driver SDK plus staged OTA management bundled.
- Hospital and clinic information points: the WF-K3600 drives a touch query station at the entrance while the hall display shows the same information set to waiting visitors in Vilnius.
- 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-K1331 runs tax, social security and real estate information lookup, with printing available on the same board.
- Shopping mall directories: the WF-K6180 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-K5270 has to stay readable under strong ambient light.
- Retail and pharmacy price or product lookup: compact stations where the WF-K8800 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 Vilnius: 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 Vilnius Buyers
The partnership structure offered to Vilnius buyers is deliberately flexible: Lithuania integrators can take the board alone, take it with the driver stack, or take it as a private-label programme.
- 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 Vilnius integrators the choice usually comes down to how much of the Lithuania project the local team wants to own versus how much it wants the factory to carry.
Frequently Asked Questions
Does the WF-K self-service query terminal Android motherboard family support a dual-screen query terminal with independent display?
Answer: Yes. AndroidSBC ships the dual-screen query terminal with independent display as a standard configuration, and the touch, printer and card reader drivers for it are integrated into the factory image rather than added by the Vilnius integrator on site.
What is the real difference between the RK3568 tier and the other silicon tiers in the WF-K family?
Answer: The RK3568 tier differs in compute headroom, display capability and NPU availability rather than in board-level interfaces. All WF-K models share the same mounting pattern, the same peripheral pinout and the same firmware baseline, so a Lithuania project can move between tiers without re-designing the enclosure.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for Lithuania?
Answer: Yes. AndroidSBC prepares the conformity file set for Lithuania as part of the order, covering CE, FCC, RoHS and REACH as applicable, plus the destination-specific route. The documents travel with the Vilnius shipment rather than following 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 Vilnius in 1-3 days, and a first bulk lot for Lithuania runs 15-30 days from confirmation.
Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-K family?
Answer: Yes, and the custom build is maintained as a branch rather than a one-off, so Vilnius partners receive updates against their own image for as long as the Lithuania programme runs.
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 Vilnius integrator needs to service Lithuania 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 Vilnius sellers. AndroidSBC prepares FBA-compliant cartons and labels for Lithuania 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 Vilnius integrators running Lithuania estates across many sites.
