TL;DR: LPDDR4X Query Terminal Board for Bank Branch Lobby
AndroidSBC peripheral desk: printer, scanner and card reader driver SDK declared production-ready serving Zagreb, Croatia. The WF-K3601 self-service query terminal Android motherboard spans the single-screen touch query all-in-one terminal 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, 1080p HDMI plus LVDS panel output, 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 Zagreb and Croatia 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
Founded as a board house and now shipping to Croatia, Wanlin Manufacturing Group builds the WF-K self-service query terminal family in Longgang, Shenzhen. Twelve models share one firmware baseline and one peripheral interface contract, which keeps Zagreb integrators from re-porting the touch, printer and card reader stack on every new project. The factory ships to Croatia 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-K3601 (single-screen touch query all-in-one terminal) 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 Croatia importers sourcing the WF-K family, the WF-K3601-A variant is the typical configuration for the hospital outpatient query rollout use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing Self-Service Query Terminal Android Motherboards for Croatia Buyers
Firmware forks are the quiet cost of query terminal projects in Croatia. When a Zagreb integrator runs several chip tiers at once, every fork multiplies the validation effort across the estate.
The compliance route matters as much as the silicon. Croatia expects CE marking with HAKOM radio interface notification, and a query terminal board shipped to Zagreb without that file set simply cannot be installed in a public building. AndroidSBC answers this with a single BOM per lot, so a Zagreb order of 64400 units carries the same silicon and firmware as the pilot batch for Croatia.
Competitive Comparison: WF-K3601 vs Competing Self-Service Query Terminal Android Boards
Compared with the general query boards Zagreb buyers see quoted for Croatia, the WF-K configuration differs mainly in platform breadth and in what ships in the carton.
- 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
Information access is being treated as infrastructure in Croatia, and that changes what is procured. Instead of one-off kiosks, Zagreb operators specify the single-screen touch query all-in-one terminal as a standard unit to be repeated across a whole estate on the same firmware.
- Volume shift to board-level sourcing: more integrators now buy the motherboard rather than the finished kiosk, which is why the WF-K3601 and WF-K3566 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-K3566 and WF-K3288 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-K3288 over boards that re-spin silicon between lots.
What this means for Zagreb is that the query board is no longer a disposable line item. It is the component that determines whether Croatia deployments can be extended rather than rebuilt.
Partner Success Story: Levant Access Services (government service hall contractor)
The Levant Access Services rollout in the GCC public service segment shows how the WF-K family from AndroidSBC supports Zagreb integrators. Levant Access Services commissioned 64400 query terminals in government service halls.
- OEM relationship: AndroidSBC private-label SKU shipped with Levant Access Services 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 HAKOM conformity, all bundled into the Shenzhen source-factory shipment.
In the words of Levant Access Services Project Director for GCC Public Service: Levant Access Services required Arabic UI support and hall information screens from one platform, and the 64400 WF-K units commissioned in Zagreb run both roles on the same firmware.
Field Report: outpatient self-service query rollout at a regional hospital group
BAOLONG, Shenzhen, September 22, 2026 - Cong Yu, AndroidSBC field desk. Thermal checks on the WF-K3601 lot covered both the indoor hall case and the outdoor information cabinet case, since a Croatia estate usually contains both. The WF-K3601 self-service query terminal Android motherboard order for Zagreb, Croatia cleared the burn-in station on schedule and is en route via the Hamburg - Shenzhen lane.
The WF-K3601 single-screen touch query all-in-one terminal production lot includes the WF-K3601-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 Croatia integrators, the HAKOM conformity plus CE marking with HAKOM radio interface notification paperwork is bundled.
Filed by Cong Yu, AndroidSBC field desk, BAOLONG, Shenzhen. Croatia integrators typically request CE plus local radio interface notification for self-service query terminal board deployments.
WF-K3601 Application Scenarios
The WF-K3601 single-screen touch query all-in-one terminal sits inside a twelve-variant WF-K self-service query terminal Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand. The WF-K3601-A configuration is the typical build for the hospital outpatient query rollout use case, with touch panel and identity peripheral driver SDK plus staged OTA management bundled.
- Hospital and clinic information points: the WF-K3601 drives a touch query station at the entrance while the hall display shows the same information set to waiting visitors in Zagreb.
- 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-K3602 runs tax, social security and real estate information lookup, with printing available on the same board.
- Shopping mall directories: the WF-K3566 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-K3288 has to stay readable under strong ambient light.
- Retail and pharmacy price or product lookup: compact stations where the WF-K3399 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 Zagreb: 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 Zagreb Buyers
Rather than a single reseller agreement, AndroidSBC offers Zagreb partners three routes into the Croatia market, each with a different level of factory involvement.
- 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 does not require exclusivity on any of the three tracks, which is deliberate: Zagreb integrators working across several Croatia verticals need room to run different models side by side.
Frequently Asked Questions
Does the WF-K self-service query terminal Android motherboard family support a single-screen touch query all-in-one terminal?
Answer: Yes. The single-screen touch query all-in-one terminal is covered by the standard WF-K driver SDK, which means the Zagreb integrator configures it rather than ports it.
What is the real difference between the RK3568 tier and the other silicon tiers in the WF-K family?
Answer: Practically, the RK3568 tier is chosen when the Croatia 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 Croatia?
Answer: Yes, and the paperwork is treated as part of the product rather than an add-on. For Croatia orders the CE, FCC, RoHS and REACH set is prepared alongside the production lot bound for Zagreb.
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 Zagreb integrator can pilot one tier for Croatia 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 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 Croatia shipments to Zagreb.
How are software updates and long-term support handled on the WF-K family?
Answer: AndroidSBC maintains a seven-year firmware window on the WF-K family, with staged OTA and rollback. Zagreb partners can freeze a revision per Croatia project and update on their own schedule.
Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-K family?
Answer: Yes, and where a Zagreb seller runs its own 3PL arrangement in Croatia, 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: AndroidSBC handles RMA and DOA replacements per production lot, which means a Zagreb partner can trace a failure back to a specific build shipped to Croatia rather than dealing with an anonymous board.
