Introduction

Imagine a world where an ATM, a smart card reader or a POS terminal doesn’t merely process transactions but senses its environment, adapts security protocols in real time, predicts fraud patterns and even communicates with the cloud for analytics and maintenance. That future is arriving, powered by the convergence of the Internet of Things (IoT) and embedded systems design.

Financial institutions are increasingly embracing this shift: connected sensors, biometric readers, edge-computing modules and secure embedded hardware are becoming the backbone of next-gen banking. As the ecosystem evolves, the design of embedded systems is not just about efficiency or speed, it’s about security, compliance, scalability and a seamless customer experience. For a technology-driven firm like Evolute Group, this transformation represents both an opportunity and a responsibility.

In this blog, we explore why IoT-enabled financial devices represent the future, how embedded systems design plays a crucial role and what it means for banks, fintechs and hardware designers alike.

Why Smart Financial Devices Are Trending

Explosive Market Growth & Demand

  • According to a recent industry report, the global market for IoT in banking and financial services was valued at USD 1,188.98 million in 2024 and is expected to reach USD 1,550.43 million in 2025, with a projected CAGR of about 30.4% through 2033.
  • Other analyses forecast even more dramatic growth: one 2025 report estimates the global IoT-BFSI market to surge from approximately USD 2.15 billion in 2024 to a staggering USD 134.40 billion by 2034 implying a ~51.2% CAGR for 2025-2034.
  • The sheer scale of digital transformation is underscored by the proliferation of connected devices worldwide. For instance, by the end-2024, total connected IoT devices are projected to reach 18.8 billion globally.

What these numbers reveal is a clear trend: banks and financial institutions are aggressively investing in IoT-enabled hardware, software and services and embedded systems design stands at the heart of this shift.

From Transactions to Intelligence

Smart financial devices, ATMs, biometric-enabled card readers, IoT-connected POS terminals and wearables for payments are no longer passive endpoints. They are sensors, data collectors and nodes in a larger network, enabling real-time analytics, dynamic authentication, device-health monitoring and predictive maintenance.

For example, as per one market analysis, in 2025 hardware remains the most lucrative segment of the IoT-BFSI market, but value is quickly shifting toward services that integrate, secure and scale large deployments often relying on embedded-system capabilities for reliability and security.

How Embedded Systems Design Powers Smart Financial Devices

Embedded Systems: The Silent Backbone

Embedded systems specialized hardware + firmware designed for dedicated tasks are essential to deliver the performance, security and reliability demanded by financial devices. Unlike PCs or general-purpose computers, embedded systems offer:

  • Real-time processing (for biometric verification, transaction validation)
  • Low-latency edge computing (so that devices can operate even when network connectivity is intermittent)
  • Hardware-level security (secure enclaves, tamper detection, cryptographic modules)
  • Energy efficiency and compact form factors, essential for devices like smart cards, wearables and portable POS terminals

When embedded systems design is paired with IoT connectivity, financial devices become intelligent capable of secure communication, adaptive behavior and data-driven decisioning.

Security, Privacy & Compliance – Non-Negotiables

With sensitive financial data flowing through these devices, security is paramount. The recent research direction is clear: simply connecting devices to the Internet isn’t enough. Next-gen systems need privacy-conscious data handling, secure authentication and decentralized analytics.

For instance, a recent technical survey explores the role of federated learning, a privacy-preserving approach where machine-learning models are trained collaboratively across devices or institutions without sharing raw data as a powerful method to build fraud detection, risk modeling, or behavioral analytics systems in IoT-enabled financial endpoints.

Similarly, advances in multi-factor authentication combining smart cards, biometrics and secure embedded hardware are being pushed forward by deep-learning-enabled biometric systems and secure on-chip cryptographic storage.

For embedded systems designers and firms like Evolute Group, this means designing hardware and firmware with strong security primitives, support for cryptographic operations, secure boot, tamper detection and a design-to-comply mindset.

Real-World Use Cases: What Smart Financial Devices Can Do

Smart ATMs & Branch Devices

Banks are retrofitting ATMs and branch infrastructure with connected sensors, environmental sensors, cameras, security locks, biometric scanners and linking them to a central IoT cloud. This enables real-time monitoring, preventive maintenance and even context-aware alerts (e.g., suspicious access attempts, malfunctions, or unusual usage patterns).

The result: higher uptime, better security and lower maintenance costs a key ROI driver for large-scale deployments.

Embedded Payment and Card Readers

Smart POS terminals or card readers, especially those with built-in biometric or secure-element chips can provide enhanced authentication, reduce fraud and support contactless or tokenized payments. Embedded systems design ensures these devices are secure, compact and performant.

Moreover, wearable devices and IoT-enabled payment endpoints (smartwatches, fitness bands, IoT-enabled home devices) illustrate a longer-term direction: integrating finance into everyday objects, a core feature of “embedded finance.”

Fraud Detection, Risk Monitoring & Compliance via Edge Analytics

With embedded systems connected via IoT, banks can deploy edge analytics analyzing data locally before sending summaries to the cloud to monitor transactions, detect anomalies and comply with regulatory requirements without compromising customer privacy.

Techniques like federated learning (mentioned above) further enable cross-institution collaboration on models (fraud detection, credit scoring) without sharing raw data preserving privacy and fostering compliance with data protection regulations.

Challenges Ahead & What Embedded Systems Designers Must Watch Out For:

High Implementation Cost & Infrastructure Complexity

Deploying IoT-enabled financial devices especially at scale (branches, ATMs, POS across regions) involves non-trivial costs: hardware procurement, secure chipsets, network infrastructure, firmware maintenance, compliance audits. Larger banks may manage, but smaller institutions may hesitate. Indeed, market reports cite high implementation cost and integration complexity among the primary restraints to IoT adoption in banking.

Security, Privacy and Regulatory Compliance

As devices proliferate, so do risks: data breaches, unauthorized access, tampering and compliance violations. Embedded systems must be designed with secure boot, hardware-based trust anchors, encryption and audit logging. Developers need to stay abreast of regulations (data privacy laws, payment compliance standards, strong-authentication mandates) especially as IoT devices handle highly sensitive financial data.

Interoperability and Scalability

Financial institutions often run legacy systems. Integrating new IoT-enabled embedded devices with legacy ATM networks, core banking platforms or third-party fintech APIs requires careful planning, modular architecture and standardized protocols. Without this, scalability becomes a serious bottleneck.

Why Now Is the Right Moment – The Confluence of Trends

Several broader technological and market trends make 2024-2025 a watershed moment:

  • The global connected-device ecosystem is expanding rapidly: IoT Analytics estimates up to 18.8 billion connected devices worldwide by end-2024.
  • Financial institutions are under increasing pressure to offer real-time, personalized and secure services while managing costs and compliance. IoT-enabled devices provide a path to achieve all three.
  • Advances in edge computing, embedded security modules, biometrics and federated learning make it technically feasible to build robust, compliant, intelligent financial devices.
  • For regions like Asia-Pacific (including India), where digital finance adoption is accelerating, the growth potential of IoT-enabled banking infrastructure is particularly high. Market reports indicate Asia-Pacific as one of the fastest-growing geographies for IoT in financial services.

For a company like Evolute Group which has experience in hardware design, embedded systems and technology consulting this convergence presents a compelling opportunity.
