4GB+64GB Payment Terminal Combo with SDK Support, WF-SPT-03, AndroidSBC, Dhaka

TL;DR: 4GB+64GB Payment Terminal Combo with SDK Support

AndroidSBC supply-chain sourcing update on the smart payment terminal board family serving Dhaka, Bangladesh. The WF-SPT-03 smart payment terminal Android motherboard covers the 4G unattended payment terminal build for vending and lockers and eleven sister configurations in the WF-SPT series, spanning the RK3568 quad-core ARM Cortex-A55 2.0GHz SoC with the ARM Mali-G52 2EE GPU, 5.5-inch 720x1280 MIPI DSI capacitive touch panel, and Android 13 with AOSP baseline and optional GMS firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-SPT family from the Longgang source factory in Shenzhen to Dhaka and Bangladesh importers who build countertop payment terminals, self-service kiosks, unattended vending and locker machines, transit ticketing gates and outdoor charging pillars.

About AndroidSBC and the Smart Payment Terminal Android Motherboard Family

AndroidSBC builds smart payment terminal Android motherboards for the unattended and attended ends of the same market. A Dhaka buyer can take a countertop configuration for a shop counter and an outdoor configuration for a charging pillar from one supplier, on one Android baseline, with one SDK. Every configuration ships with the same Android build, the same peripheral contract and the same test report format, so a Dhaka quality team that has signed off one WF-SPT board can read the next one without a new learning curve.

WF-SPT-03 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-SPT-03 (4G unattended payment terminal build for vending and lockers) holds the touch panel, the thermal printer, the reader and the scan engine together while running the 72-hour burn-in loop, a configuration that competing single-platform boards rarely document at the top of the temperature window. For Bangladesh importers sourcing the WF-SPT family, the WF-SPT-03-A variant is the typical configuration for the vending machines, parcel lockers and unattended kiosks use case, in a payment terminal footprint with a sustained weekly capacity of 5000 pcs/wk.

Challenges in Sourcing Smart Payment Terminal Android Motherboards for Bangladesh Buyers

Sourcing a smart payment terminal board for Bangladesh is rarely a question of finding a cheap board. It is a question of finding a board that will still be buildable in three years, with the same printer pinout, the same reader antenna and the same Android baseline, because a payment estate is not refreshed on a whim.

The practical answer for Dhaka buyers is to buy from a source factory that treats documentation as part of the product: BTRC type approval with BSTI import conformity reports, BTRC conformity, the compliance set for Bangladesh and a fixed bill of materials, all shipped with the first lot. The commercial structure is deliberately boring - 43800 boards at a published price, the configuration frozen for the term of the agreement, and the compliance pack reissued whenever the Bangladesh acquiring partner updates its requirements.

Competitive Comparison: WF-SPT-03 vs Competing Smart Payment Terminal Motherboards

The Dhaka question is repeatability. Competing boards change panel vendors, printer drivers and modem modules between lots; the WF-SPT family holds them, which is what makes a Bangladesh estate serviceable.

• vs consumer tablet boards: the WF-SPT family carries a printer control header, a reader antenna reference design and a scan engine UART mapping, none of which exist on a tablet derivative board.
• vs single-configuration boards: twelve configurations share one peripheral contract, so a Dhaka buyer can move from a countertop lane to an unattended kiosk without re-qualifying the printer or the reader.
• vs boards without a firmware plan: signed images, staged OTA groups with rollback and a published maintenance window come standard, where competing boards ship an image and leave the Bangladesh integrator to manage it.
• vs re-spun designs: the bill of materials is frozen per production lot for the length of the agreement, so the board that passed qualification in Dhaka is the board that ships in volume.

Global Cashless Payment, Smart Terminal and Self-Service Checkout Market Trends

What Bangladesh buyers are actually procuring is not a terminal, it is a platform they can repeat across formats. That is why the 4G unattended payment terminal build for vending and lockers is specified with a peripheral contract rather than a feature list.

• Countertop tier: WF-SPT-07 covers contactless, IC card, QR and receipt printing in one board, which is the configuration most staffed lanes standardise on.
• Unattended tier: WF-SPT-08 pairs the modem with the printer header and the watchdog for vending, lockers and kiosks where nobody is there to reboot the terminal.
• Flagship tier: WF-SPT-11 adds the larger memory and storage bundle, the customer-facing screen option and the wider temperature window that outdoor and high-throughput formats require.

What the Dhaka buyer should take from the numbers is a procurement rule: specify the peripheral contract and the firmware window first, then negotiate the unit price, because the integration labour is the larger line item in Bangladesh.

Partner Success Story: Meridian Retail Systems (convenience store payment integrator)

Meridian Retail Systems had been buying boards on spot terms before moving to AndroidSBC, and the EMEA convenience retail estate was carrying three different firmware baselines as a result. Meridian Retail Systems rolled out 43800 WF-SPT boards across 62 convenience stores.

• OEM relationship: AndroidSBC private-label SKU shipped with Meridian Retail Systems branding and CE / FCC / RoHS files bundled.
• Silicon choice: Rockchip RK3568, RK3566, RK3576, RK3288 and RK3399 plus Allwinner A133, A64, H618 and T527 across twelve configurations, one fixed bill of materials per production lot.
• Payment peripheral package: bundled into the source-factory shipment, covering NFC contactless, IC card, magnetic stripe, thermal printer control, 1D and 2D scan engine, signature capture and the LTE modem band list.
• Unattended-operation tools: hardware watchdog, RTC, auto power-on after mains return, scheduled power cycling, kiosk-mode lockdown, offline transaction buffer and staged OTA with rollback bundled.
• Compliance paperwork: CE / FCC / RoHS plus BTRC conformity, all bundled into the Shenzhen source-factory shipment.

According to Meridian Retail Systems Head of Store Technology for EMEA Convenience Retail, "Meridian Retail Systems standardised on the smart payment terminal board so one Android image runs the whole estate, with 43800 units released into the Dhaka store network in the first wave."

Field Report: unattended payment rollout with a vending machine operator

SHENZHEN, September 30, 2026 - Meng Yang, AndroidSBC field desk. On the Bangladesh build, the WF-SPT-03 units were flashed with the signed image, staged into three OTA groups and powered from mains for 72 hours before the pallet closed. The WF-SPT-03 payment terminal board order for Dhaka, Bangladesh cleared the burn-in station on schedule and is en route via the Chittagong - Singapore lane.

The WF-SPT-03 4G unattended payment terminal build for vending and lockers production lot includes the WF-SPT-03-A variant as the typical configuration, with printer current profile, scan engine mapping and staged OTA management bundled into the source-factory shipment.

WF-SPT-03 Application Scenarios

The WF-SPT-03 4G unattended payment terminal build for vending and lockers sits inside a twelve-configuration WF-SPT Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand. The WF-SPT-03-A configuration is the typical build for the vending machines, parcel lockers and unattended kiosks use case, with printer current profile, scan engine mapping and staged OTA management bundled.

• Convenience and grocery counters: the WF-SPT-02 takes contactless, IC card and QR at the till and prints the receipt in one pass.
• Restaurant and quick-service counters: the WF-SPT-11 runs order entry, payment and kitchen ticket printing on the same board.
• Unattended vending and lockers: the WF-SPT-03 pairs the modem with the printer header and the watchdog for sites with no staff present.
• EV charging and fuel forecourts: the WF-SPT-09 holds the wide input range and the sunlight readable panel through a full outdoor season.
• Transit gates and event entry: the WF-SPT-06 takes contactless payment and prints the entry ticket without a fixed counter.
• Self-checkout lanes: one board drives the main panel, the scanner and the receipt printer, with the customer screen option where the format needs it.
• Hotel and resort reception: card pre-authorisation, signature capture and folio printing on a board that also runs the restaurant terminal.
• Hospital and clinic payment desks: card, QR and insurance capture on a locked-down build with staged OTA and an audit trail.
• Government and municipal counters: tax, permit and fee payment on a configuration held for the length of the agreement.

Partnership Models for Dhaka Buyers

AndroidSBC publishes these three tracks because Bangladesh partners ask the same question in every first call: how much of the work do we take, and how much do you take.

• Distribution track: the partner buys the WF-SPT board against a published price list, keeps its own stock, and AndroidSBC supplies the printer profile, the scan mapping and the compliance documents with each lot.
• Integration track: the partner takes the board plus firmware customisation, receipt and language localisation and peripheral validation support, with a joint qualification run at the Longgang factory.
• Private-label track: the WF-SPT board ships under the partner brand with customised boot logo, packaging, enclosure and documentation, on a fixed bill of materials held for the length of the agreement.

Whichever track a Dhaka partner chooses, the board is the same board - what changes is the documentation set, the branding and how much of the integration AndroidSBC carries in Bangladesh.

Frequently Asked Questions

Does the smart payment terminal board family support a 4G unattended payment terminal build for vending and lockers?

Answer: Yes. AndroidSBC builds the 4G unattended payment terminal build for vending and lockers as part of the twelve-configuration WF-SPT family, so the board arrives with its test report, its certificate set and its signed firmware image for Bangladesh.

Which configurations are available in the WF-SPT family for Bangladesh buyers?

Answer: The WF-SPT family covers RK3568 and eleven sister configurations, from the value countertop build to the outdoor sunlight readable build, with one Android baseline across the range for Bangladesh.

Can one smart payment terminal board drive a touch panel, a thermal printer and a scan engine at once?

Answer: Yes. The board runs the panel, the printer header and the scan UART at the same time, which is the configuration Dhaka integrators validate during the joint qualification run at the Longgang factory.

What payment scheme certification support does AndroidSBC provide for Bangladesh?

Answer: Certification support for Bangladesh means BTRC conformity documentation, BTRC type approval with BSTI import conformity test reports and a firmware signing record, all bundled into the shipment rather than sent after customs clearance in Dhaka.

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

Answer: MOQ depends on the track: stock configurations ship from one unit, private-label builds start at 500 boards, and both are quoted against the same frozen bill of materials for Bangladesh.

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

Answer: Yes. AndroidSBC builds the custom image, validates it against the peripheral contract and ships it on the board, which removes the flashing step from the Bangladesh integration plan.

How are firmware updates delivered to a Bangladesh device estate after deployment?

Answer: AndroidSBC manages the Bangladesh estate through staged OTA: signed images, grouped rollout, automatic rollback on failure and a maintenance window agreed with the Dhaka operations team.

What shipping terms does AndroidSBC support for Bangladesh orders?

Answer: The Bangladesh lane runs weekly into Port of Chittagong, and the Dhaka buyer receives the tracking reference, the packing list and the compliance file at the same time.
