TL;DR: Query Kiosk Printer Board Export for Hospital Information Point
AndroidSBC export desk: OEM, ODM and distribution tracks open on the WF-K self-service query board family serving Porto, Portugal. The WF-K3288 self-service query terminal Android motherboard spans the legacy query terminal refresh with hall display and eleven sister models in the WF-K series, all built on the RK3288 quad-core ARM Cortex-A17 1.8GHz SoC with the ARM Mali-T764 GPU, 1080p HDMI plus LVDS, and Android 10 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-K family from the Longgang source factory in Shenzhen to Porto and Portugal 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
AndroidSBC manufactures the WF-K self-service query terminal Android motherboard family at the Wanlin Manufacturing Group plant in Longgang, Shenzhen. For Portugal buyers the series is deliberately broad: entry A133 boards for simple lookup stations, RK3568 workhorses for dual-screen work, and RK3588 parts where Porto projects need 8K or AI acceleration. The factory ships to Portugal on a factory-direct basis, with the driver SDK, compliance files and mounting drawings bundled into the same carton as the boards.

| Process node | 28nm | Older 28nm or 40nm process |
| GPU | Mali-T764 | Older Mali-450 or basic GPU |
| NPU / AI | none | No NPU on competing entry boards |
| Memory | 2GB DDR3 | DDR3 1GB / 2GB on competing boards |
| Storage | 16GB eMMC | eMMC 5.0 8GB / 16GB on competing boards |
| Display output | 1080p HDMI plus LVDS | Single HDMI 1080p only on competing boards |
| Touch support | 10-point capacitive touch | Resistive single-touch on competing boards |
| Operating system | Android 10 | Android 8 or Android 9 on competing boards |
| Connectivity | WiFi 5 plus Bluetooth 5.0 plus Gigabit Ethernet | WiFi 4 plus 10/100M Ethernet on competing boards |
| Query peripherals | Capacitive touch, thermal printer, document scanner, card reader | No bundled touch, printer or scanner driver SDK on competing boards |

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-K3288 (legacy query terminal refresh with hall 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 Portugal importers sourcing the WF-K family, the WF-K3288-A variant is the typical configuration for the installed-base query terminal refresh use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing Self-Service Query Terminal Android Motherboards for Portugal Buyers
Procurement teams in Portugal 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 Porto.
On top of that sits the arrival port question. Hardware bound for Porto lands through Port of Lisbon, and documents that do not line up with the CE marking with ANACOM radio interface notification route used in Portugal delay the whole installation programme. For the 6th consecutive quarter, AndroidSBC has held the Porto allocation against one fixed BOM, which is why a 182400-unit programme can be dated rather than estimated.
Competitive Comparison: WF-K3288 vs Competing Self-Service Query Terminal Android Boards
What separates the WF-K board from competing query boards in Porto 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
Growth in the query terminal segment is being driven by labour economics as much as by technology. In Portugal the legacy query terminal refresh with hall display lets operators cover longer hours with the same headcount, and Porto 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-K3288 and WF-K8800 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-K8800 and WF-K8801 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-K8801 over boards that re-spin silicon between lots.
For Porto integrators the implication is straightforward. Competing on the query terminal itself is difficult; competing on the integration package that reaches Portugal is where margin survives.
Partner Success Story: Levant Access Services (government service hall contractor)
The Levant Access Services case in the GCC public service segment is a working example of how the WF-K family from AndroidSBC supports Porto integrators. Levant Access Services commissioned 182400 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 ANACOM conformity, all bundled into the Shenzhen source-factory shipment.
As Levant Access Services Project Director for GCC Public Service put it: Levant Access Services required Arabic UI support and hall information screens from one platform, and the 182400 WF-K units commissioned in Porto run both roles on the same firmware.
Field Report: installed-base query terminal refresh at a social security service hall
YANTIAN, Shenzhen, September 22, 2026 - Chu Lin, AndroidSBC field desk. Field returns on the WF-K3288 lot were monitored per station, which is how Portugal integrators trace a fault back to a specific production run. The WF-K3288 self-service query terminal Android motherboard order for Porto, Portugal cleared the burn-in station on schedule and is en route via the Lisbon - Shanghai lane.
The WF-K3288 legacy query terminal refresh with hall display production lot includes the WF-K3288-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 Portugal integrators, the ANACOM conformity plus CE marking with ANACOM radio interface notification paperwork is bundled.
Filed by Chu Lin, AndroidSBC field desk, YANTIAN, Shenzhen. Portugal integrators typically request CE plus local radio interface notification for self-service query terminal board deployments.
WF-K3288 Application Scenarios
The WF-K3288 legacy query terminal refresh with hall 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-K3288-A configuration is the typical build for the installed-base query terminal refresh use case, with touch panel and identity peripheral driver SDK plus staged OTA management bundled.
- Hospital and clinic information points: the WF-K3288 drives a touch query station at the entrance while the hall display shows the same information set to waiting visitors in Porto.
- 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-K3600 runs tax, social security and real estate information lookup, with printing available on the same board.
- Shopping mall directories: the WF-K3601 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-K3602 has to stay readable under strong ambient light.
- Retail and pharmacy price or product lookup: compact stations where the WF-K3566 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 Porto: 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 Porto Buyers
Three tracks are open to Porto integrators, and the difference between them is where the Portugal 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 Portugal partners start on the distribution track, add the integration track once volumes justify it, and move to private label when Porto brand recognition matters more than margin per unit.
Frequently Asked Questions
Does the WF-K self-service query terminal Android motherboard family support a legacy query terminal refresh with hall display?
Answer: Yes, and it is qualified on the same production line as the rest of the family. The legacy query terminal refresh with hall display runs on the WF-K baseline image that Portugal buyers receive, so there is no separate integration project.
What is the real difference between the RK3288 tier and the other silicon tiers in the WF-K family?
Answer: The RK3288 tier sits at a specific point on the price-versus-headroom curve. Below it the boards suit single-screen information lookup; above it they support dual-screen independent display and heavier video work, and AndroidSBC documents that mapping for Porto buyers.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for Portugal?
Answer: Yes. Compliance files for Portugal are bundled into the source-factory shipment to Porto, and AndroidSBC provides the underlying test reports as well as the certificates on request.
What are the MOQ and lead time for a first order of the WF-K self-service query terminal family?
Answer: For Porto the entry MOQ is low enough to validate one site before committing to an estate, with 1-3 day samples and a 15-30 day first bulk lead time for Portugal.
Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-K family?
Answer: Yes. Custom ROM work on the WF-K family is scoped per Porto project rather than sold as a generic service, which keeps the Portugal deliverable tied to a specific deployment.
How are software updates and long-term support handled on the WF-K family?
Answer: The WF-K family runs a staged OTA channel with rollback. Updates are released against the shared firmware baseline, and Porto integrators can hold a Portugal estate on a known revision while a new build is validated.
Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-K family?
Answer: Yes. Boards for Porto can be routed straight into Amazon FBA or a third-party 3PL in Portugal, with the labelling and packing specification confirmed before the lot is packed.
How are RMA and DOA replacements handled on the WF-K self-service query terminal family?
Answer: DOA and RMA cases are managed by lot, with replacement units supplied from a matching build so a Porto partner does not end up with mixed firmware across a Portugal estate.
