TL;DR: EMC Compliant Query Terminal Board for Bank Branch Lobby
AndroidSBC reliability desk: query terminal boards clear a 72-hour continuous touch soak test serving Gothenburg, Sweden. The WF-K3602 self-service query terminal Android motherboard spans the query terminal with document scanner and A4 printer 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 output plus eDP secondary panel, 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 Gothenburg and Sweden 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
The WF-K family is the self-service query terminal line of AndroidSBC, a Wanlin Manufacturing Group export brand. Production sits in the Longgang source factory in Shenzhen, and the twelve models span the RK3588, RK3568, RK3566, RK3288, RK3399, A133, H618 and T527 platforms for Gothenburg and Sweden projects. The factory ships to Sweden on a factory-direct basis, with the driver SDK, compliance files and mounting drawings bundled into the same carton as the boards.

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-K3602 (query terminal with document scanner and A4 printer) 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 Sweden importers sourcing the WF-K family, the WF-K3602-A variant is the typical configuration for the document-printing query service rollout use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing Self-Service Query Terminal Android Motherboards for Sweden Buyers
Procurement teams in Sweden usually compare query terminal boards on price first, then find that integrating three vendors for touch, printing and identity peripherals costs more than the difference between a cheap board and the right one for Gothenburg.
On top of that sits the arrival port question. Hardware bound for Gothenburg lands through Port of Stockholm, and documents that do not line up with the CE marking with PTS radio interface notification route used in Sweden delay the whole installation programme. For the 1st consecutive quarter, AndroidSBC has held the Gothenburg allocation against one fixed BOM, which is why a 109500-unit programme can be dated rather than estimated.
Competitive Comparison: WF-K3602 vs Competing Self-Service Query Terminal Android Boards
The table below puts the WF-K self-service query terminal board against what a Gothenburg integrator typically finds on competing query boards sold into Sweden.
- 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
Growth in the query terminal segment is being driven by labour economics as much as by technology. In Sweden the query terminal with document scanner and A4 printer lets operators cover longer hours with the same headcount, and Gothenburg projects are typically justified on exactly that basis.
- Volume shift to board-level sourcing: more integrators now buy the motherboard rather than the finished kiosk, which is why the WF-K3602 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 Gothenburg integrators the implication is straightforward. Competing on the query terminal itself is difficult; competing on the integration package that reaches Sweden is where margin survives.
Partner Success Story: Siam InfoTerm Holdings (hospital group technology supplier)
The Siam InfoTerm Holdings rollout in the Southeast Asia healthcare segment shows how the WF-K family from AndroidSBC supports Gothenburg integrators. Siam InfoTerm Holdings supplied 109500 query boards to hospital outpatient information desks.
- OEM relationship: AndroidSBC private-label SKU shipped with Siam InfoTerm Holdings 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.

According to Siam InfoTerm Holdings Managing Director for Southeast Asia Healthcare: Siam InfoTerm Holdings rolled the WF-K single-screen board into outpatient information desks, and the 109500 units delivered to Gothenburg came with the printer and card reader drivers already integrated.
Field Report: self-service document query and print rollout at a tax service hall
LONGGANG, Shenzhen, September 22, 2026 - Bei Chen, AndroidSBC field desk. The WF-K3602 production run was validated against the touch stack first, because Sweden deployments mix 10-point and 20-point panels across the same estate. The WF-K3602 self-service query terminal Android motherboard order for Gothenburg, Sweden cleared the burn-in station on schedule and is en route via the Stockholm - Shanghai lane.
The WF-K3602 query terminal with document scanner and A4 printer production lot includes the WF-K3602-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 Sweden integrators, the PTS conformity plus CE marking with PTS radio interface notification paperwork is bundled.
Filed by Bei Chen, AndroidSBC field desk, LONGGANG, Shenzhen. Sweden integrators typically request CE plus local radio interface notification for self-service query terminal board deployments.
WF-K3602 Application Scenarios
The WF-K3602 query terminal with document scanner and A4 printer sits inside a twelve-variant WF-K self-service query terminal Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand. The WF-K3602-A configuration is the typical build for the document-printing query service rollout use case, with touch panel and identity peripheral driver SDK plus staged OTA management bundled.
- Hospital and clinic information points: the WF-K3602 drives a touch query station at the entrance while the hall display shows the same information set to waiting visitors in Gothenburg.
- 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 Gothenburg: 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 Gothenburg Buyers
Three tracks are open to Gothenburg integrators, and the difference between them is where the Sweden partner wants to add its own value.
- 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.
In practice Sweden partners start on the distribution track, add the integration track once volumes justify it, and move to private label when Gothenburg brand recognition matters more than margin per unit.
Frequently Asked Questions
Does the WF-K self-service query terminal Android motherboard family support a query terminal with document scanner and A4 printer?
Answer: Yes. AndroidSBC treats the query terminal with document scanner and A4 printer as a stock case on the WF-K family and validates it on every tier that could plausibly run it, including the entry and industrial parts.
What is the real difference between the RK3568 tier and the other silicon tiers in the WF-K family?
Answer: The RK3568 tier carries its own process node, GPU and NPU rating, and AndroidSBC publishes all three per model so Gothenburg integrators can compare on facts rather than on marketing labels.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for Sweden?
Answer: Yes. AndroidSBC handles the compliance route for Sweden directly, and Gothenburg buyers receive the certificate set with the shipping documents so customs clearance is not held on paperwork.
What are the MOQ and lead time for a first order of the WF-K self-service query terminal family?
Answer: MOQ is quoted per model rather than per family, so a Gothenburg integrator can pilot one tier for Sweden without buying across all twelve. Samples take 1-3 days and bulk lots 15-30 days.
Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-K family?
Answer: Yes. AndroidSBC develops custom Android ROM and custom Linux builds for the WF-K family, with the work scoped against the Gothenburg requirement and validated on the same production rig that ships Sweden orders.
How are software updates and long-term support handled on the WF-K family?
Answer: Updates are delivered through a staged OTA channel with rollback support, and Gothenburg integrators decide when a Sweden estate moves to a new build rather than being pushed onto it.
Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-K family?
Answer: Yes, and where a Gothenburg seller runs its own 3PL arrangement in Sweden, AndroidSBC ships to that warehouse on the same terms as a direct buyer order.
How are RMA and DOA replacements handled on the WF-K self-service query terminal family?
Answer: DOA units are replaced from the next available lot, and RMA cases are tracked by lot number. For Gothenburg integrators this keeps Sweden deployments serviceable without holding large local stock.
