What is IoT in app development?

The Internet of Things, or IoT, refers to the interconnected network of physical devices and sensors — “things” — that collect and exchange data. The IoT is used everywhere: from oil and gas industry to vending machines. Think about smart homes where you can control locks, lights, curtains, or AC through an app on a phone.  Or, consider vehicle that can spot obstacles and connect with the infrastructure with special sensors. All these devices are connected to the Internet, creating an ecosystem of appliances that can be managed from one place.

In the fintech industry, the Internet of Things works similarly. The prime example is smart branches — bank locations, where connected sensors and systems can monitor occupancy levels and predict wait time so the managers can coordinate staff better and find ways to improve customer experiences.

IoT technology helps with real-time data collection, analytics, and automated decision-making. This has completely transformed how financial apps provide services and operate.

How IoT is impacting the fintech industry

The Internet of Things is one of the hottest technologies in the fintech industry. The global IoT in the banking and financial services market is growing steadily. Its size was estimated at USD 57.55 billion in 2023 and is expected to reach USD 68.15 billion by the end of 2024. Many businesses — from Stripe to Mastercard, IBM, and Microsoft — implement IoT features to elevate the level of services they provide.

Here is how IoT technologies transformed fintech services.

Smart payments

Smart payments are financial transactions processed without human intervention, with the help of IoT devices for example, when you buy a coffee and pay by holding your smartwatch to a terminal or when paying at a grocery store by tapping your phone. IoT technology collects your payment data and communicates it between devices without having to swipe a physical card.

Contactless payments are widely popular in many countries, including the United States and Europe, where over half of consumers prefer it over traditional card swipes.

Advanced security

When you use IoT in a financial platform, enhanced security is required to safeguard data that is being transferred between devices. The more devices get connected via IoT technology, the more app owners need to elevate their security measures to protect financial information. These include biometric authentication like FaceIDs and fingerprints or physical measures like access control to prevent unauthorized access.

Better customer experience

IoT devices generate much data about customer behavior, patterns, preferences, and needs. These analytics are used in fintech products to improve customer experience and come up with better ways of delivering services. For instance, through IoT, banks can collect insights about customer spending habits and provide tailored promotional offers.

Precise cash flow management

Cash flow refers to all money coming in and out of a business. This includes cash from customers, investments, payroll expenses, loans, etc. Effective cash flow management means you always track and control where business assets are.

As an example of how IoT technology helps with this, think of ATMs. Banks know exactly how much cash is in each ATM at the moment, what banknotes are prevalent, and what machines need to be serviced soon.

Process automation

IoT-connected devices create an ecosystem that helps with automating the processes in a fintech organization. For example, this removes the chance of human errors when transferring data — instead of a manual input, devices automatically communicate with each other and exchange information.

4 fintech apps that implemented IoT features

Let’s shift from theory to practice and take a look at fintech apps that have implemented IoT features in their products.

Purrweb’s experience in fintech and IoT development

At Purrweb, we’ve helped numerous startups integrate IoT features. Our expertise in fintech app development, combined with our deep understanding of IoT technology, enables us to create cutting-edge apps on time while still staying within the budget. Here are some examples.

Vendify

Vendify

Vendify is an IoT application for smart vending machines that sell fresh food. Unlike a traditional vending machine, with Vendify the purchase happens on a smartphone: the user just scans a QR code on the fridge, opens the door, grabs a meal, and leaves.

It works because every product has an RFID tag, which allows the backend to not only know what products were taken out but also how many meals are left and what needs to be restocked. When the fridge detects what was taken, it sends this info to the app that charges the user’s credit card.

EnerGO

EnerGo

EnerGO is a startup for renting power banks at subway stations, cafés, and coffee shops. The main challenge was to develop a React Native app and integrate it with IoT stations that the client sent us from China. We spent a lot of time studying the hardware to learn how to communicate with the station.

Although we initially planned on making one app, there were two more apps that came along:

    • The app for advertising — for stations that play video playlists and show advertising banners.
    • The app for maintenance — for service workers to help them set up and maintain the stations more efficiently.

Crypto Wallet

Crypto Wallet

Crypto Wallet is an alternative to Metamask, which is a platform for both crypto coin storage and exchange. When users sign up for Crypto Wallet, they can either import an existing wallet or create a new one right in the app. For the visuals, we took inspiration from Metamask but went a step further and refreshed outdated design elements like a burger menu.

Final thoughts

IoT, or the Internet of Things, connects multiple devices into an ecosystem and establishes communication between them and the cloud. These devices exchange data to help companies gain insights into customer behavior, operational performance, or market trends.

IoT in fintech is on the rise, and it’s not just a trans that will come and go — the technology has been around for years. If you want to get ahead of the curve, it is crucial not only to use IoT features but also to combine them with the recent trending technologies: 5G, AI & machine learning, blockchain, and others.

At Purrweb, we develop apps that connect various IoT devices into an automated ecosystem with a focus on modern and robust UI/UX design and cost-efficient software development approaches. We always consider trending technologies as something we can implement, but only as long as they are needed in the product and fit within our client’s budget.
