Facial Feature Extraction Board for Supermarket Checkout Lane, WF-P3399, AndroidSBC, Lagos

TL;DR: Facial Feature Extraction Board for Supermarket Checkout Lane

AndroidSBC field desk: POS rollout map updated across supermarkets, restaurants, hotels and fuel forecourts serving Lagos, Nigeria. The WF-P3399 POS Android motherboard spans the dual-screen high definition POS with 4K promotion wall and eleven sister models in the WF-P series, all built on the RK3399 dual Cortex-A72 1.8GHz plus quad Cortex-A53 SoC with the ARM Mali-T860 MP4 GPU, HDMI 2.0 plus eDP output at 4K@60Hz, and Android 11 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-P family from the Longgang source factory in Shenzhen to Lagos and Nigeria importers who run supermarket checkout lanes, convenience counters, restaurant tills, hotel front desks, fuel forecourt cabinets and unattended payment kiosks.

About AndroidSBC and the POS Android Motherboard Family

For Lagos integrators the WF-P family answers the question that usually blocks a rollout: will the board drive both the cashier screen and the customer display, and will the cash drawer fire on the right pulse. AndroidSBC ships the dual-screen configuration, the RJ11 or RJ12 drawer header and the printer handshake as a validated set, not as a list of interfaces on a datasheet. Peripheral validation happens on the Longgang bench with the actual printer, scanner and drawer models the Lagos integrator intends to use, and the result is written into the shipment file rather than left to the integrator to discover on site.

WF-P3399 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-P3399 (dual-screen high definition POS with 4K promotion wall) 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 Nigeria importers sourcing the WF-P family, the WF-P3399-A variant is the typical configuration for the flagship store checkout plus media wall use case, with a sustained weekly capacity of 5000 pcs/wk.

Challenges in Sourcing POS Android Motherboards for Nigeria Buyers

Dual-screen POS is where most competing boards fail quietly. They list two display interfaces, but the second lane is a mirror rather than an independent framebuffer, so the customer display cannot carry a separate promotion loop.

The fiscal layer is handled in firmware. Receipt templates, log retention and the fiscal printer handshake are configured before shipment, and the Port of Lagos lane is booked against a production slot so the Lagos pilot batch lands inside the store opening window. AndroidSBC logged the 4th shipment to Lagos on September 23, 2026 - 171600 boards on the Lagos - Shanghai lane, each serialised against its burn-in record and each carrying the same firmware baseline.

Competitive Comparison: WF-P3399 vs Competing POS Android Boards

Four differences decide whether a Nigeria POS rollout survives its second year, and they are all visible before the first lane goes live.

• Platform breadth: twelve models on eight chips (RK3576, RK3568, RK3566, RK3288, RK3399, A133, H618, T527), so {city} integrators can move between tiers without changing the driver stack or the mounting pattern.
• Bundled integration: receipt printer, barcode scanner, cash drawer, customer display, NFC and card reader driver SDK ships in the carton; competing POS 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 POS boards reaching {city}.

Global POS Terminal and Smart Checkout Market Trends

The Nigeria picture follows the global pattern: cashless adoption sets the demand, and the replacement of legacy registers sets the volume. A Lagos integrator who can offer a board that drops into an existing enclosure wins on installation cost as much as on unit price.

• Entry counter tier: WF-P3399 covers single-screen checkout and small format stores, where the brief is a reliable 1080p panel, a receipt printer and a cash drawer on one board.
• Dual-screen mainstream tier: WF-P3601 drives the cashier screen and the customer display independently, which is the configuration most restaurant and supermarket rollouts standardise on.
• AI and unattended tier: WF-P3602 carries the NPU, the wide temperature window and the watchdog behaviour that face payment counters and outdoor cabinets require.

The eight-tier WF-P line exists because Lagos rollouts are not uniform. One chain will use four of the twelve models, and the point is that all four share one driver contract.

Partner Success Story: Kanto Shokai Systems (convenience store POS integrator)

A Kanto Shokai Systems programme in the Japanese convenience segment illustrates how the WF-P family from AndroidSBC supports Lagos integrators on the ground. Kanto Shokai Systems installed 171600 WF-P boards across 118 convenience counters.

• OEM relationship: AndroidSBC private-label SKU shipped with Kanto Shokai Systems branding and CE / FCC / RoHS files bundled.
• Silicon lock: Rockchip RK3576 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 thermal printer, receipt printer, barcode scanner, QR scanner, cash drawer, customer display, NFC reader, RFID reader, magnetic stripe reader, IC card reader, PIN pad, fingerprint reader and face recognition camera.
• 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 NCC / SONCAP conformity, all bundled into the Shenzhen source-factory shipment.

As Kanto Shokai Systems Platform Manager for Japanese Convenience explained: Kanto Shokai Systems qualified the WF-P board on Japanese receipt typography and standby power, and 171600 units went into the Lagos store network in the first release.

Field Report: flagship store checkout and media wall installation

NANSHAN, September 23, 2026 - Chu Lin, AndroidSBC field desk. The WF-P3399 board designated for the dual-screen high definition POS with 4K promotion wall application was pulled from the same production lot as the pilot batch, so the Nigeria team received an identical configuration. The WF-P3399 POS Android motherboard order for Lagos, Nigeria cleared the burn-in station on schedule and is en route via the Lagos - Shanghai lane.

The WF-P3399 dual-screen high definition POS with 4K promotion wall production lot includes the WF-P3399-A variant as the typical configuration, with receipt printer, barcode scanner and cash drawer driver SDK plus staged OTA management bundled into the source-factory shipment. For Nigeria integrators, the NCC type approval with SONCAP conformity paperwork is bundled.

Filed by Chu Lin, AndroidSBC field desk, NANSHAN. Nigerian buyers ask for NCC approval and prefer the model with 4G fallback, because fixed-line connectivity at the counter is unreliable.

WF-P3399 Application Scenarios

The WF-P3399 dual-screen high definition POS with 4K promotion wall sits inside a twelve-variant WF-P POS Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand. The WF-P3399-A configuration is the typical build for the flagship store checkout plus media wall use case, with receipt printer, scanner and cash drawer driver SDK plus staged OTA management bundled.

• Supermarket and hypermarket checkout: the WF-P3399 drives the cashier screen while the second lane carries the customer display or the promotion wall in Lagos.
• Convenience and small format stores: the WF-P6180 fits a narrow counter with a receipt printer, a barcode scanner and a cash drawer on one board.
• Restaurants and quick service: the WF-P5270 runs the order screen plus a kitchen display output, with the customer display showing the order total.
• Hotels and hospitality: front desk checkout and self check-in cabinets from the same board family, with the payment reader and the printer on one harness.
• Unattended retail and vending: the WF-P7600 holds a 7x24 duty cycle in a cabinet with no staff to reset it.
• Fuel forecourts and parking: the WF-P7601 runs the outdoor payment cabinet, where the wide temperature window and the watchdog matter more than raw CPU.
• Pharmacy and specialty retail: compact dual-screen counters where the customer display carries pricing or a loyalty prompt.
• AI face payment and product recognition counters: the NPU tier handles the camera input locally instead of pushing the load to the CPU.
• Retrofit programmes in Lagos: the same board re-uses the existing enclosure, panel and counter harness, so an installed estate can be upgraded lane by lane.

Partnership Models for Lagos Buyers

AndroidSBC does not force a track on Nigeria partners. The three below are the ones that actually get used.

• Distribution track: the partner buys the WF-P 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-P 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 is recruiting local partners in Nigeria on all three tracks, and the qualification evidence needed to start is the same in each case.

Frequently Asked Questions

Does the WF-P POS Android motherboard family support a dual-screen high definition POS with 4K promotion wall?

Answer: Yes. The dual-screen high definition POS with 4K promotion wall is a stock configuration on the WF-P POS Android motherboard family from AndroidSBC. All tiers are validated against the same firmware build and the same peripheral interface before shipment to Lagos.

Which silicon tiers are available in the WF-P family for Nigeria buyers?

Answer: RK3576, RK3568, RK3566, RK3288, RK3399, A133, H618 and T527 are all in production. The RK3399 tier specified here is validated for Nigeria compliance with the same evidence pack as the rest.

Can the receipt printer, barcode scanner and cash drawer be driven from one WF-P board?

Answer: Yes, and the configuration is documented per lot. The Lagos partner receives the interface map and the validation report with the shipment, so the counter can be wired without trial and error.

What is the minimum order quantity and the sample lead time for Nigeria?

Answer: Samples ship in 1-3 days and the sample MOQ is a single board. Volume production runs on a 15-30 day lead against the frame agreement, and the price list covers tiered volume breaks.

Is custom ROM, boot logo or pre-installed app development available?

Answer: Available on all three tracks. AndroidSBC does AOSP builds, BSP porting, custom boot animation, custom logo and pre-installed apps, with the result held as the Lagos partner reference image.

How are firmware updates delivered to a Nigeria estate after deployment?

Answer: Updates go out through the staged OTA channel bundled with the driver SDK. The Lagos partner can hold lanes, pilot on ten, and revert any wave that misbehaves.

What shipping terms does AndroidSBC support for Nigeria orders?

Answer: FOB Shenzhen, CIF and EXW terms are all supported, with export customs clearance handled at the factory. The Lagos partner chooses the Incoterm that matches its broker arrangement.

What happens if a board fails in the field in Nigeria?

Answer: AndroidSBC holds service stock for Lagos partners on a frame agreement, so a failed board is replaced from that stock while the root-cause analysis runs in parallel.
