Fintech embedded & IoT development services we provide
The payments and fintech sector demands hardware that is tamper-resistant, low-latency, and certified to rigorous security standards. FoogleTech delivers production-grade firmware and IoT engineering for payment terminals, ATMs, crypto hardware wallets, and biometric systems. Our engineers combine embedded C/C++, secure element integration, and real-time OS expertise to build financial hardware that passes PCI-PTS, EMVCo, and FIPS 140-2 certification.
Payment Terminal Firmware
POS terminals and mPOS readers demand rock-solid firmware with EMV, NFC, and contactless support. We develop PCI-compliant firmware in C/C++ for payment hardware, integrating secure bootloaders, encrypted key storage, and remote OTA update systems.
ATM & Kiosk Software
ATM and self-service kiosk platforms require high-availability embedded software with robust error handling. We engineer RTOS-based ATM control software, XFS middleware integrations, and secure remote management agents for fleet operators.
Crypto Hardware Wallet Development
Hardware wallets demand meticulous firmware security. We design and develop firmware for secure microcontrollers, implementing key generation, BIP-32/39/44 standards, display drivers, and secure communication protocols for crypto custody devices.
Biometric Authentication Devices
Fingerprint readers, iris scanners, and facial recognition modules for banking authentication require precision firmware. We build sensor drivers, template matching algorithms, and ISO/IEC 19794-compliant biometric systems for financial security hardware.
IoT-Connected Financial Hardware
Smart ATMs, connected card readers, and IoT-enabled branch equipment need secure cloud connectivity. We build MQTT/HTTPS device agents, certificate-based provisioning, and encrypted telemetry pipelines for connected financial devices.
Secure Element & HSM Integration
Financial hardware requires tamper-resistant secure elements and HSMs for key management. We integrate SE050, ATECC608, and nShield HSMs into payment devices, implementing cryptographic APIs and secure key lifecycle management.
Embedded Linux for Fintech Platforms
Payment kiosks and fintech gateways often run embedded Linux. We build custom Yocto/Buildroot images for ARM-based fintech hardware, hardened with SELinux policies, LUKS disk encryption, and minimal attack-surface configurations.
Fintech Backend & API Development
Hardware needs a backend. We build Django and FastAPI transaction processing services, device management APIs, and real-time fraud detection backends that complement your embedded hardware deployments.
A confidential fintech client partnered with FoogleTech to redesign their next-generation mPOS terminal firmware. Our engineers delivered PCI-PTS certified firmware with NFC, EMV, and contactless support in 14 weeks, enabling the client to launch in three new markets simultaneously. Read the full case study →
Benefits of custom embedded fintech solutions
1. Certified Security
Custom firmware lets you design security from the ground up — secure boot chains, encrypted key storage, and hardware-backed attestation — enabling PCI-PTS and FIPS 140-2 certification without legacy constraints.
2. Reduced BOM Cost
Purpose-built firmware runs on lower-cost MCUs, letting you right-size your bill of materials. Off-the-shelf OS platforms often force oversized hardware; custom embedded code gives you precise resource control.
3. Full IP Ownership
You own every line of firmware, every protocol stack, and every device management agent we write. No vendor lock-in, no royalties, no dependency on a third party's roadmap.
4. Faster Certification
Our engineers have shipped PCI-compliant and EMVCo-certified hardware. We understand the certification process and structure our development milestones to align with lab testing cycles, reducing time-to-certification.
5. Long-term Maintainability
Financial hardware has a 7–10 year field life. We write clean, documented, unit-tested embedded code with clear abstraction layers so your team can maintain and extend the platform for years without rewriting from scratch.
Which fintech operators benefit from custom embedded development?
A wide range of fintech and payment hardware companies benefit from FoogleTech's embedded engineering services. Examples include:

Technical Discovery
We audit your hardware BOM, security requirements, and certification targets. Our embedded architects define the firmware architecture, RTOS selection, and BSP strategy before a single line of code is written.
Firmware Development & Integration
We build in two-week firmware sprints with continuous integration on target hardware. Driver development, protocol stack integration, and security hardening happen in parallel with your hardware team's board bring-up.
Certification & Production Launch
We prepare your firmware for PCI, EMVCo, or FIPS lab testing, fix certification findings, and support production firmware signing and key injection for your manufacturing line.
Frequently Asked Questions (FAQ)
We work with ARM Cortex-M/A, RISC-V, and x86-based platforms. Common targets include STM32, NXP i.MX, Renesas, and Raspberry Pi Compute Module. We develop for bare-metal, FreeRTOS, Zephyr, and embedded Linux environments.
We implement secure boot with code signing, hardware-backed encrypted key storage (SE050, ATECC608), tamper detection, anti-debugging measures, and minimize attack surface by stripping unused OS components. All security design is reviewed against PCI-PTS and FIPS 140-2 requirements.
Yes. We have experience structuring firmware development milestones to align with EMVCo and NFC Forum certification lab testing cycles. We prepare test harnesses, fix lab findings, and support interoperability testing.
Yes. We build secure OTA update agents with differential update support, rollback capability, cryptographic signature verification, and delta compression to minimize cellular data usage for field-deployed terminal fleets.
A typical payment terminal firmware project from BSP bring-up to EMV certification takes 6–12 months depending on peripheral complexity, security requirements, and certification scope. We accelerate timelines by reusing our certified cryptographic libraries and protocol stacks.
Yes. We have full-stack embedded and backend teams. Our Django and FastAPI engineers build device management platforms, transaction APIs, and fraud analytics backends that are designed from day one to pair with the firmware we're writing.
Costs vary based on MCU complexity, peripheral count, RTOS selection, and certification scope. We offer fixed-price milestone-based engagements and time-and-materials models. Contact us for a scoping call.
All firmware, drivers, and backend code written by FoogleTech is assigned to you upon project completion. We include IP assignment in all contracts. No vendor lock-in — you own the full codebase.
