What Is Internet of Things (IoT)?
The Internet of Things (IoT) refers to a vast network of physical objects, or "things," embedded with sensors, software, and other technologies that enable them to connect and exchange data with other devices and systems over the internet. These smart devices can range from everyday household items like smart appliances and wearable technology to complex industrial machinery. In the realm of financial technology (fintech), IoT leverages this interconnectedness to collect and analyze real-time data, driving enhanced efficiency, security, and personalized services within the financial sector53, 54, 55.
History and Origin
The concept of connected devices predates the formal naming of the Internet of Things. Early examples include a modified Coca-Cola vending machine at Carnegie Mellon University in the early 1980s, which allowed programmers to remotely check its stock and temperature. The term "Internet of Things" itself was coined by British technology pioneer Kevin Ashton in 199951, 52. While working at Procter & Gamble, Ashton, then co-founder of the Auto-ID Center at the Massachusetts Institute of Technology (MIT), used the phrase during a presentation to describe a system where the internet would be connected to the physical world via ubiquitous sensors, particularly focusing on Radio-Frequency Identification (RFID) for supply chain management. His vision highlighted the limitations of humans in data capture and the potential for computers to gather information about things autonomously, thereby reducing waste and costs50. Walmart and the U.S. Department of Defense were among the first large organizations to embrace Ashton's model of inventory tracking using RFID and the Internet of Things in the early 2000s49.

Interpreting the Internet of Things (IoT)
Interpreting the Internet of Things in a financial context involves understanding how the vast amounts of data generated by connected devices can be translated into actionable insights and automated processes. For financial institutions, IoT data provides a granular view of operations and customer behavior, enabling more informed investment decisions and optimized resource allocation. It shifts the paradigm from reactive to proactive financial management, allowing for predictive analytics and more dynamic service delivery. For instance, sensors can monitor the condition of physical assets used as collateral for loans, providing continuous real-time data on their status and value39. This allows lenders to better assess and manage risk associated with those assets.
Hypothetical Example
Consider a commercial real estate company that has secured a loan from a bank to manage a portfolio of properties. The bank implements an IoT solution to monitor certain conditions within these buildings. Smart sensors installed in each property track various environmental parameters like temperature, humidity, and energy consumption, as well as operational data like occupancy rates and maintenance schedules.
This data is continuously transmitted to the bank's system. If a sudden, uncharacteristic spike in energy usage is detected in a property, or if occupancy rates drop significantly without explanation, the IoT system triggers an alert to the bank's risk management team. This real-time insight, derived from IoT, allows the bank to proactively engage with the borrower to understand the cause of the anomaly. It provides an early warning signal of potential issues that could impact the property's value or the borrower's ability to repay the loan, enabling the bank to take preventative measures rather than reacting after a problem has escalated.
Practical Applications
The Internet of Things (IoT) has a growing number of practical applications across the financial services industry, impacting various facets from customer interactions to back-end operations:
- Payments and Transactions: IoT enables seamless contactless payments through wearable devices and mobile point-of-sale systems, revolutionizing how consumers conduct transactions.37, 38 For example, smartwatches can facilitate tap-and-pay options, speeding up transactions and enhancing convenience.36
- Personalized Banking: Financial institutions utilize data from smart devices to offer tailored financial products and services. Banks can analyze spending habits or lifestyle data to suggest personalized loan offers, insurance policies, or investment opportunities.34, 35
- Fraud Detection and Security: IoT devices play a critical role in enhancing cybersecurity and fraud detection. Real-time monitoring of device activities and transactional patterns helps identify anomalies and suspicious behavior, leading to quicker intervention and prevention of fraudulent activities.32, 33 This includes advanced authentication methods like biometrics at ATMs or for mobile banking.30, 31
- Supply Chain Finance: IoT provides real-time visibility into supply chain management by tracking goods and assets, optimizing inventory levels, and predicting potential disruptions.28, 29 This enhanced transparency can streamline invoice financing and reduce financial risks for all parties involved. An academic publication further elaborates on how the integration of AI and IoT is revolutionizing supply chain finance by enhancing inclusivity, efficiency, and intelligence through real-time data and automated processes.27
- Asset Management: Connected sensors on ATMs or other bank equipment can monitor their status and performance, enabling predictive maintenance, reducing downtime, and optimizing cash management.26
Limitations and Criticisms
Despite its transformative potential, the Internet of Things (IoT) in finance faces several notable limitations and criticisms, primarily concerning data privacy and cybersecurity.
One significant concern is the sheer volume of data collected by IoT devices, which often includes highly sensitive personal information. This raises questions about how this data is stored, processed, and shared, and who has access to it. Consumers are often required to accept complex privacy policies, which may grant companies broad rights to use and share their data, sometimes without the consumer's full understanding or control.24, 25 The possibility of personally identifiable information being misused or inadvertently leaked is a major risk.23
Cybersecurity is another critical challenge. The interconnected nature of millions of IoT devices creates an expanded attack surface for malicious actors. Many IoT devices may lack robust security measures, such as strong authentication, encryption, or regular software updates, making them vulnerable to breaches.20, 21, 22 An unsecured IoT device could serve as a gateway for hackers to access broader financial systems, potentially leading to significant financial losses or reputational damage for financial institutions.19 The Federal Trade Commission (FTC) released a report highlighting these security and privacy issues, recommending that companies "build security into devices at the outset, rather than as an afterthought in the design process" and consider "data minimization."17, 18
Furthermore, the lack of standardized protocols and fragmented ecosystems can lead to compatibility issues and hinder the seamless integration of diverse IoT solutions within complex financial infrastructures.15, 16 The high initial costs of implementing and maintaining IoT systems, along with a potential shortage of skilled professionals, also present obstacles to widespread adoption.14
