    Top Technologies for Fintech Software Development

    Fintech, or financial technology, has become an appealing alternative to traditional banking. It has transformed the financial services industry and changed the way we manage money. Therefore, many companies who understand the powerful impact of the technology are incorporating fintech into their existing processes. Others are developing fintech startups from scratch.

    However, like many other endeavors, new businesses require planning and elaborate preparation –  especially ones related to an emerging industry like fintech. So, when deciding on the core features and tech stack for your startup, it’s crucial to examine the main market requirements and trends, and – most importantly –  the most frequently used and reliable technologies and software.

    In this post, we’ll walk you through the details so you can enter the market with a viable fintech product built with the best programming language for the finance industry.

    Fintech Market Overview

    The evolution of fintech has propelled both pure fintech players and digital-ready banks forward and caused them to share markets and leave traditional banking in the dust. Because fintech is evolving rapidly thanks to a host of technologies such as artificial intelligence, robotic process automation, IoT, big data, and cloud computing, the future of this industry is almost limitless.

    Today, a big part of fintech involves innovating traditional services. Startups develop new solutions and offer them to existing businesses, specifically to those that are establishing mobile wallets and payment systems. In particular, mobile banking has gained considerable popularity among young people, who prefer to use online banking apps.

    According to Statista research, the largest fintech market segment is digital payments. They generated $4,406,431 million US dollars in transaction value in 2020, an amount that’s likely to double by 2024.

    The pace of fintech adoption depends on mobile internet usage, the credibility of technological companies, as well as the levels of trust in and access to traditional financial services in certain regions. Local investment in fintech, in turn, depends on regional variables and determines access to capital.

    Software Development Trends in 2021

    Today, the fintech industry is full of innovative solutions and services. Robotics, cloud technologies, shared ledgers, and other solutions are seen more frequently in projects that are setting new trends and strengthening competition in the financial market. Let’s look at those trends.

    The Internet of Things and Secure Payment

    With so many smart, interconnected devices appearing every day, IoT technologies will see comprehensive development in coming years.

    Specialists will continue to refine contactless payment methods. Although people can already pay for purchases with their smartphones, in the near future, contactless payment will also become possible on many other devices.

    Personalization

    Personalization is another global trend that will determine the further evolution of the financial industry. It forces fintech companies to offer personalized services and create websites, email messages, popular fintech apps, notifications, payment confirmations, invoices, chatbots, and messages on social media websites that are all focused on the client. Personalization comes first in many areas, especially retail banking.

    Digital Banking

    The erosion of customer trust in old-fashioned traditional banking has created a space for alternative digital options – also known as challenger banks or non-banks – in the financial industry. These players are known for their use of technology, but also for offering higher interest rates, lower fees, and superior customer support.

    Two of the most popular digital bank ventures include the Fidor and Zelf. Both are virtual-only banks that enable the user to avoid red tape. With fintech applications, there’s no need to waste time visiting a bricks-and-mortar banks — now, it’s possible to complete all financial transactions on the go.

    Regardless of the undisguised skepticism of players in the traditional financial sector, challenger banks keep on growing and affecting different segments of the financial market. The rising interest in digital solutions is highlighted in a Facebook white paper that reveals that 92% of millennials in the US express distrust in traditional financial institutions. Further, 45% of them are ready to switch to fintech solutions.

    The rapid development of fintech may leave the impression that it’s driving banks out of business. However, if they can’t get a finance license, startups are most likely to collaborate with banks by providing them with innovative solutions in return for access to the bank’s client base.

    AI and Robotics

    The global spread of financial technologies has led to drastic changes and forced banks to align their operations with those changes. That’s where digitalization comes into play. It’s leading robotic machines to replace bank employees to gain efficiency and higher profits. Chatbots are replacing call centers and customer care specialists, as communication can be handled by robots just as plausibly as with humans.

    The role of artificial intelligence in fintech is highlighted in the Mizuho Financial Group case. Mizuho, a Japanese megabank, will cut about 19 thousand jobs by 2026 and replace them with computers to keep up with changing industry trends.

    Fintech Market Requirements

    The main challenge when selecting the optimal technology for a fintech app is the requirement that it performs as efficiently as possible. Six directions that are critical for a fintech software development company include the technology’s uniqueness, safety, credibility, agility, data handling, and flexibility.

    Uniqueness

    New fintech ventures are launched almost every day. That makes the competition fierce and obligates you to enter the market with a unique and outstanding product. Before successfully bringing your startup to life, make sure you determine a specific niche for your project and all the advantages your fintech solution provides.

    Safety

    Because all fintech apps deal with money and financial data, they must ensure secure access and protect data from theft. So, to maintain your clients’ trust in your brand, prevent even small failures in the safety system by using the most sophisticated technologies.

    Credibility

    People who switch to fintech solutions expect that they will not experience any downtime when obtaining financial services. The task for a financial technology provider is to ensure instant and unimpeded access to the users’ money.

    Agility

    When entering the market with their projects, fintech companies face cutthroat competition with industry leaders who have been occupying the niche for years. To stand out, the technology you use must be agile enough to let you react to changing market trends promptly and apply changes to your product. Being flexible is vital.

    Data Handling

    Insights about clients – including their purchasing behavior, credit ratings, and income – help financial companies build their business and provide an excellent user experience. However, to manage and analyze customer information properly, fintech startups must stick to technology used in data science.

    Flexibility

    Every single company, no matter what niche it’s in,  is a part of a business ecosystem. That means your startup project should be flexible enough to quickly integrate with other systems and popular fintech apps.
