Query Terminal Document Scanner Board for Bank Branch Lobby, WF-K3602, AndroidSBC, Colombo

TL;DR: Query Terminal Document Scanner Board for Bank Branch Lobby

AndroidSBC software desk: Android 15 baseline and staged OTA channel published for the WF-K family serving Colombo, Sri Lanka. 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 Colombo and Sri Lanka 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 Colombo and Sri Lanka projects. The plant holds a standing allocation of LPDDR4X and eMMC for the WF-K line, which is how Colombo projects keep their lead times stable across quarters.

WF-K3602 Technical Specifications

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 Sri Lanka 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 Sri Lanka Buyers

Query terminal reliability in Colombo 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 Sri Lanka issues the purchase order.

There is also a documentation discipline problem. Many suppliers quote TRCSL / SLSI for Sri Lanka but cannot produce the underlying TRCSL type approval with SLSI import conformity evidence when a Colombo integrator is audited mid-project. The practical answer for Colombo is a fixed bill of materials per production lot, which is how a 85300-unit order stays repeatable for Sri Lanka across the year.

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 Colombo integrator typically finds on competing query boards sold into Sri Lanka.

• 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

The category is broadening from single-purpose lookup stations into multi-role information points. Sri Lanka operators now expect the query terminal with document scanner and A4 printer to drive a hall display as well, which is why Colombo projects increasingly specify dual-screen configurations.

• 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-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.

For Sri Lanka buyers, the market shift means the query terminal decision is now a multi-year supply decision, and Colombo projects are increasingly evaluated on that basis.

Field Report: self-service document query and print rollout at a tax service hall

NANSHAN, Shenzhen, September 22, 2026 - Huan Xi, AndroidSBC field desk. The WF-K3602 production run was validated against the touch stack first, because Sri Lanka deployments mix 10-point and 20-point panels across the same estate. The WF-K3602 self-service query terminal Android motherboard order for Colombo, Sri Lanka cleared the burn-in station on schedule and is en route via the Colombo - Singapore 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 Sri Lanka integrators, the TRCSL type approval with SLSI import conformity paperwork is bundled.

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 Colombo.
• 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-K3399 runs tax, social security and real estate information lookup, with printing available on the same board.
• Shopping mall directories: the WF-K1330 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-K1331 has to stay readable under strong ambient light.
• Retail and pharmacy price or product lookup: compact stations where the WF-K6180 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 Colombo: 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 Colombo Buyers

The commercial menu for Colombo integrators has three entries, and Sri Lanka partners usually start on one before adding the others as volumes grow.

• 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 Sri Lanka partners start on the distribution track, add the integration track once volumes justify it, and move to private label when Colombo 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, and it is qualified on the same production line as the rest of the family. The query terminal with document scanner and A4 printer runs on the WF-K baseline image that Sri Lanka buyers receive, so there is no separate integration project.

What is the real difference between the RK3568 tier and the other silicon tiers in the WF-K family?

Answer: The RK3568 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 Colombo buyers.

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

Answer: Yes. Compliance files for Sri Lanka are bundled into the source-factory shipment to Colombo, 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: The first order MOQ on the WF-K family is set for pilot runs rather than container loads. Colombo buyers can start small, then scale once Sri Lanka field data is in hand, with 15-30 day bulk lead times.

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 Sri Lanka shipments to Colombo.

How are software updates and long-term support handled on the WF-K family?

Answer: Software updates on the WF-K family are staged rather than immediate, with rollback available at each step, which matters when a Colombo estate is live and Sri Lanka sites cannot tolerate an unplanned outage.

Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-K family?

Answer: Yes. AndroidSBC regularly ships the WF-K family into Sri Lanka fulfilment centres on behalf of Colombo sellers, handling the labelling and carton marking at the source factory.

How are RMA and DOA replacements handled on the WF-K self-service query terminal family?

Answer: RMA and DOA units are handled against the production lot, since every WF-K board is logged against its firmware revision and burn-in result before it leaves Shenzhen. Colombo partners report against the lot number and AndroidSBC matches it to the rig log.
