RK3588 Self-Service Query Terminal Board for Bank Branch Lobby, WF-K3399, AndroidSBC, Ljubljana

TL;DR: RK3588 Self-Service Query Terminal Board for Bank Branch Lobby

AndroidSBC release: twelve-model WF-K self-service query terminal motherboard family opens for volume orders serving Ljubljana, Slovenia. 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 Ljubljana and Slovenia 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 Ljubljana and Slovenia projects. The factory ships to Slovenia on a factory-direct basis, with the driver SDK, compliance files and mounting drawings bundled into the same carton as the boards.

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 Slovenia 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 Slovenia Buyers

Query terminal reliability in Ljubljana is a supply-chain question as much as an engineering one: the board has to be available on the same BOM for years, not just at the moment Slovenia issues the purchase order.

On top of that sits the arrival port question. Hardware bound for Ljubljana lands through Port of Hamburg, and documents that do not line up with the CE marking with AKOS radio interface notification route used in Slovenia delay the whole installation programme. For the 3rd consecutive quarter, AndroidSBC has held the Ljubljana allocation against one fixed BOM, which is why a 18200-unit programme can be dated rather than estimated.

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

The comparison below reflects the configurations AndroidSBC ships to Ljubljana against the typical competing query board offered in Slovenia.

• 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 Slovenia, and that changes what is procured. Instead of one-off kiosks, Ljubljana operators specify the dual-screen HD query terminal with mirrored display 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-K3399 and WF-K1331 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-K1331 and WF-K6180 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-K6180 over boards that re-spin silicon between lots.

That trend favours board-level suppliers in Slovenia: the Ljubljana 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 Ljubljana integrators. Nordweg Innbyggertorg deployed 18200 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 AKOS conformity, all bundled into the Shenzhen source-factory shipment.

As Nordweg Innbyggertorg Programme Director for Nordic Public Service explained: Nordweg Innbyggertorg replaced counter-side lookup binders with the WF-K compact board, and 18200 units went into Ljubljana 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 - Ke Xin, AndroidSBC field desk. The WF-K3399 production run was validated against the touch stack first, because Slovenia deployments mix 10-point and 20-point panels across the same estate. The WF-K3399 self-service query terminal Android motherboard order for Ljubljana, Slovenia cleared the burn-in station on schedule and is en route via the Hamburg - Shenzhen lane.

The WF-K3399 dual-screen HD query terminal with mirrored display production lot includes the WF-K3399-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 Slovenia integrators, the AKOS conformity plus CE marking with AKOS radio interface notification paperwork is bundled.

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 Ljubljana.
• 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-K5270 runs tax, social security and real estate information lookup, with printing available on the same board.
• Shopping mall directories: the WF-K8800 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-K8801 has to stay readable under strong ambient light.
• Retail and pharmacy price or product lookup: compact stations where the WF-K3600 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 Ljubljana: 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 Ljubljana Buyers

The partnership structure offered to Ljubljana buyers is deliberately flexible: Slovenia 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.

Whatever track a Ljubljana partner selects, the underlying board, firmware baseline and compliance files are identical, which keeps Slovenia conversations about commercial terms rather than technical risk.

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 a stock configuration on the WF-K self-service query terminal Android motherboard family from AndroidSBC. All tiers are validated against the same firmware build and the same peripheral interface before shipment to Ljubljana.

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

Answer: The RK3399 tier is the right choice when the Ljubljana deployment needs exactly its level of video decode and AI capability; above that the extra headroom is paid for but not used, and below it the board cannot sustain the workload.

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

Answer: Yes, and where Slovenia requires a local registration step AndroidSBC supplies the technical file that the Ljubljana partner submits, rather than leaving the integrator to reconstruct 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 Ljubljana in 1-3 days, and a first bulk lot for Slovenia runs 15-30 days from confirmation.

Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-K family?

Answer: Yes. The WF-K baseline is Android, but Slovenia buyers frequently need a custom Linux image or a stripped Android build, and AndroidSBC delivers both from the Longgang engineering team for Ljubljana.

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 Ljubljana integrator needs to service Slovenia 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 Ljubljana sellers. AndroidSBC prepares FBA-compliant cartons and labels for Slovenia 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 Ljubljana integrators running Slovenia estates across many sites.
