FinTech Hardware Products — Overview

Overview

SGT Systems Limited's FinTech hardware catalogue equips banks, mobile financial service (MFS) providers, payment service providers (PSPs), microfinance institutions, agent banking networks and retail merchants in Bangladesh with the secure, locally supportable hardware they need to deliver modern payment experiences. The catalogue spans 10 SKUs across POS terminals, EMV card readers, QR scanners, biometric devices, agent kits and back-office cash-management equipment.

The Bangladeshi payments landscape has evolved at speed: Bangla QR is mainstream, contactless EMV is being rolled out across major banks, agent banking has reached every upazila, and digital onboarding is now expected to be biometric and instantaneous. Banks and MFS providers need a hardware supply chain that is fast, locally certified, locally serviced, and integrated with their existing switch, core-banking and MFS platforms. Imported hardware from China or Europe often satisfies the technical specifications but fails on lead-time, certification, repair logistics and after-sales support; SGT's value proposition is purpose-built to fill that gap.

All products in our FinTech range carry the security certifications and Bangladesh Bank approvals required for their respective use cases, integrate with the dominant switches and MFS platforms via standard interfaces, and ship with a configuration and remote-management server (TMS) that lets operations teams push key rotations, parameter updates and application versions to thousands of devices without a field visit.

This document is the catalogue's umbrella reference. Detailed certifications, switching-interface specifications and security profiles are available per SKU on request, subject to the appropriate NDA for sensitive cryptographic material.

        - merchant onboarding

Merchant- and agent-facing devices communicate over a hardened TLS channel to the customer's acquirer host or MFS platform using the agreed switching interface (ISO 8583 or REST). Out-of-band, the same devices register with the SGT Terminal Management System (TMS), which inventories the device, pushes application and parameter updates, manages cryptographic keys and provides operational dashboards. Both channels operate over 4G LTE with Wi-Fi fallback (or vice versa) so that the device stays in service across network conditions.

Industries we serve in this category

• Commercial banks: EMV POS deployment, agent banking kits, branch biometric eKYC
• MFS providers: bKash / Nagad / Rocket agent and merchant acceptance devices
• Payment service providers: branded POS estate management, TMS as a service
• Microfinance institutions: field-officer kits, biometric loan disbursement
• Retail chains and QSRs: integrated POS for restaurants, supermarkets, pharmacies
• Government and utility payments: bill collection kiosks, agent acceptance

Customisation & OEM

Customisation in FinTech is highly regulated and almost always done under a signed scope and NDA. Within those bounds we routinely offer: custom branding on plastics, splash screens and printed receipts; custom application development on Android Smart POS (Java/Kotlin); switch-interface customisation for proprietary message formats; integration with the customer's existing TMS or MDM; and bundled solution kits (e.g. an agent-banking kit tailored to a specific microfinance institution's workflow). For larger banks we can also operate the TMS as a managed service, offloading day-to-day estate operations.

Ordering & logistics

• Lead times: QR scanners and biometric devices 2 weeks; POS terminals 3–4 weeks; agent banking kits 4–6 weeks
• MOQ: 1 unit for evaluation, 25–50 units for pilot, 200+ for production deployments with TMS
• Warranty: 12-month standard, with replacement-on-failure for bank deployments above 500 units
• Logistics: all POS shipments include tamper-evident packaging; key injection done at SGT secure room or at customer site
• Compliance documentation: certification packs supplied with every order to support Bangladesh Bank reporting

Support & documentation

FinTech hardware is supported under a banking-grade SLA. Customers receive a named technical account manager, 24/7 Tier-2 support, replacement-on-failure for failed terminals within agreed timeframes, and quarterly fleet-health reviews. Our team also supports the customer's own Tier-1 helpdesk with diagnostic playbooks, scripted resolutions for common merchant issues, and training programmes for in-house engineers. Where the customer prefers, we operate the entire post-sale support function as a managed service.

For pre-sales discussions, certification documentation requests or pilot proposals, contact us via the contact form — we will arrange an NDA-protected technical briefing.

Reference deployments and outcomes

SGT FinTech products are in service with commercial banks, MFS providers, microfinance institutions and large retail acquirers. A typical bank agent-banking rollout deploys 1,000–5,000 agent kits across Bangladesh, with each kit comprising a tablet, biometric fingerprint device, thermal printer and connectivity. Time from bank PO to commissioned, customer-serving agent fleet is typically 8–12 weeks — a fraction of the lead-time of comparable imported-and-integrated solutions. For PSP and acquirer customers, our TMS-as-a-service offering allows the customer to scale their merchant terminal estate from hundreds to tens of thousands of terminals without scaling their internal operations team proportionately.

For retail merchants, particularly QSR and pharmacy chains, our Android Smart POS terminals replace the multi-device clutter (separate POS, PIN-pad, QR scanner, receipt printer) at the counter with a single device, simplifying the counter footprint and reducing the merchant's training burden.

Cryptographic key management

Cryptographic key management is the most operationally sensitive part of any FinTech hardware deployment, and SGT operates a documented, audited key-management lifecycle covering injection, rotation, retirement and destruction. New-generation devices are key-injected at the SGT secure room in Dhaka under dual-control supervision, with full chain-of-custody documentation supplied to the customer. Remote key download (RKD) capability is built into the TMS so that customers can rotate keys across thousands of devices without recalling them to a central location. End-of-life devices are returned to SGT for secure key zeroisation and certified destruction, with the customer receiving a destruction certificate.

For customers operating their own key-injection facilities, we provide tooling and documentation to let them perform key injection themselves while retaining the rest of the TMS workflow.

Compliance posture

The FinTech catalogue is engineered to satisfy the compliance requirements applicable in Bangladesh and the surrounding markets. Card-accepting devices are certified to EMVCo L1 and L2 (contact and contactless) and to the appropriate level of PCI PTS. QR-acceptance devices are tested against the Bangla QR specification. Biometric devices use ISO 19794 templates and, where required, STQC-certified sensors. Cellular and biometric devices carry BTRC type approval. Devices intended for use in Bangladesh Bank-regulated services are submitted for and carry the appropriate Bangladesh Bank approvals.

Compliance is not a one-time event — we maintain a compliance roadmap that tracks the evolution of standards (e.g. PCI PTS v7, EMVCo SBMP) and keeps our product line aligned with the latest version of each.

Frequently asked questions

Can I use these devices with my existing acquirer / switch?

Yes. Our devices support ISO 8583 (89 and 93 variants) and REST/JSON switching interfaces. We have reference integrations with most major switches used in Bangladesh and the wider region.

How long does device certification take?

Device-level EMVCo and PCI certifications are already in place for all our card-accepting SKUs. The customer-specific certification (acquirer host integration, scheme certification) typically takes 4–8 weeks per scheme, and we support the customer through that process.

Can the TMS be operated by my team?

Yes. The TMS is delivered as a multi-tenant SaaS that you log in to, or as a single-tenant on-prem deployment that you operate. We also offer TMS-as-a-managed-service, where SGT operates the TMS on the customer's behalf.
