Open banking refers to the practice of allowing third-party providers to access banking data, with the customer’s authorization, in order to offer a wide range of financial services.

A note from our CEO

Dear Reader,

In today's digital age, banking is undergoing a significant transformation. The way we manage our finances has changed dramatically over the years and continues to evolve with constant surprises. This evolution is happening thanks to advances in technology and the emergence of novel solutions for managing our finances. One of the driving forces behind the changes taking place is the emergence and rise in importance of open banking.

Open banking refers to the practice of allowing third-party providers to access banking data, with the customer's authorization, in order to offer a wide range of financial services. This allows customers to have more control over their finances, make better decisions and have access to a wider range of services.

API integration, in contrast, allows different systems to communicate with each other and exchange data seamlessly. This has paved the way for a new era of innovation in financial services, where customers can now access services from different providers, all on one platform.

At Railwaymen, we believe that open banking and API integration is the future of the financial sector. That's why we're proud that the applications we develop are perfectly aligned with this trend and guarantee customers cutting-edge solutions to make their daily lives easier.

Our custom applications guarantee greater control over finances, allow you to make better decisions based on posted data and provide access to a wider range of services.

This e-book is intended as a comprehensive guide that explores the benefits and opportunities of open banking and API integration. I am confident that it will provide valuable insights and practical advice for companies looking to enter this new era of banking.

Enjoy the read,
Łukasz Młynek

The future of banking

In the larger business community, making predictions about the future is often laughed off as fortune-telling. However, it is clear that the banking industry has been through major changes recently. Digitalization has given the development of banking a tangible boost. Traditional institutions are losing influence in favor of mobile applications which empower users with the ability to manage their finances from anywhere on earth. These trends raise both interest and concerns among users and entrepreneurs who must adapt to the new reality.

A Deloitte report on the future of banking in 2030 states that a lot depends on the direction the markets take now. To fit into the landscape of the 2030s, financial institutions will face increased pressure to take a number of actions. The company lists as many factors that are worth paying special attention to when preparing a business strategy for banking companies.

Orchestrating influence on the new ecosystem

Due to the various types of regulations of the banking industry, most FinTech businesses focus on analyzing or transferring funds. In order to do so, it is necessary to cooperate with banking institutions to achieve access to accounts and transactions. Therefore, many companies bet on open banking combined with API integrations.

In the following chapters, we will introduce you to the concept of open banking and API integrations and prove how important they are for the current generation of  financial solutions. In the later part of this document you will find examples of companies which made their digitalization goals, along with statements from their teams on how the change in approach to traditional services has affected the health of their businesses.

I am convinced that we will look back at the introduction of Open Banking in 2018 and recognise it as one of the most important moments for the FinTech community and the financial services sector as a whole. Open Banking presents remarkable and exciting opportunities for consumers and the business community – without it, we couldn’t deliver our core offering at Hydr.

Open Banking

Modern banking is changing under the influence of new technologies.

Until recently, banks were the sole owners of their customers’ private data related to finances or even marital status. Currently, based on the information collected about the customer, financial institutions can easily determine the habits of consumers and assign them appropriate behavior patterns. This data is used to personalize offers, as well as to make decisions on granting loans, credits and other financial services. A major step in the development of the realities of financial services as we know them so far has been open banking.

What is the purpose of open banking?

The mission of open banking is not only to make it easier for customers to access their financial data, but also to create a system that allows them to make the best choice in terms of available offers. The financial services industry can boost innovation and competitiveness by allowing customers to give consent to share their confidential data with third-party FinTech applications.

What is the main idea behind open banking?

The aim of open banking is to connect enterprise apps with banks so that users have more transparency in their spending. This system comprises thoroughly integrated services  and is responsible for the development of financial products. As opposed to traditional banking, open banking makes use of the technological network of financial institutions to facilitate information exchange. The role of FinTech applications in the open banking system is to help users set budgets, allocate funds and coordinate accounts.

In many European countries, including the UK, open banking has already been introduced as a legal regulation and its implementation is under state supervision. The purpose of this is to ensure the security and confidentiality of customers’ financial data and encourage the development of the financial services market.

One example of the regulation is PSD2 (Payment Services Directive 2), which is in force in the European Union countries. This regulation enables bank customers to manage their finances more efficiently and proactively, increases the security of electronic transactions and stimulates the development of the financial services market. All this for the sake of consumer interests and stable economic development in Europe.

For more details about the PSD2 directive, please refer to the Railwaymen blog, where we posted the article “What is PSD2, and how does it affect the FinTech industry?”.

Is open banking a safe solution?

The procedure for opening accounts and obtaining bank statements is simplified, and the quality of all data gathered through open banking is checked to ensure that it complies with the highest standards. No operation on our account data can be performed without the customer’s express consent.

Banks and payment institutions are automatically required by regulations to use silent authentication, which means that when carrying out transactions, such as those made using mobile banking applications, the system may request extra authentication from the user. Customers may be required to authenticate by entering a pre-defined PIN code or by entering a single use code sent to their phone number. When it comes to the criteria connected to security, all banks are required to agree on and adhere to the same set of rules.

While the European Union has introduced the PSD2 Directive which regulates open banking, the process is still being adjusted for regulatory action in the United States. According to Forbes, 2023 could be a key year for sustaining open banking in the US. The condition is that an agreement is reached between all parties responsible for financial management standards.

Did you know that machine learning algorithms can be used as protection against fraud or money laundering? By analyzing a large amount of financial data, machine learning algorithms can identify patterns and occurring trends in search of anomalies and potential vulnerability points. As a result, financial institutions can better manage risks, which translates into improved financial stability and customer security.

Challenges and Considerations for Open Banking and API Integration

1

API effectiveness and reliability

The ability of banks to create public APIs is not a guarantee of reliable performance. This is one of the reasons that testing the APIs should be a priority when developing banking applications. If this aspect is neglected, it could lead to performance problems that translate into reputational losses for the company and affect the overall perception of open banking.

2

Identity command

Another challenge in open banking idea is identity management. This factor is very important, especially from the perspective of developers who are looking for a reliable solution to identify and track users of banking applications. Currently, public APIs only provide access to data from financial institutions, but without the ability to accurately identify them.

3

Lack of universal compliance standards

In some geographic areas, one can find regulations whose role is to standardize open banking. And although in the case of EU countries we are dealing with the PSD2 directive, from a global perspective, clear guidelines for all countries are yet to be established. The current state generates some complications due to the lack of a clear framework defining the technical standards for banking integration.

4

Security concerns

Of all the challenges of open banking, the most important is implementing the highest security standards. Protecting customers’ personal data is a high priority for financial institutions. However, no suitable solution has yet been found to eliminate all potential threats. Therefore, great attention has to be paid to analyzing third-party applications, which are difficult to verify and control, and may have sensitive information. Cybersecurity is making rapid progress each year and the solutions employed in securing banking apps are sure to improve at the same pace. Nevertheless, a lot in this regard depends on banks and developers, who have to devote a lot of their energy to make open banking applications fully secure and free of any security gaps.

What opportunities can digital solutions provide your company? Which ones will continue to support the financial industry in the future? In the chapter that follows, we will endeavor to answer these and many other questions.

Optimization enables enterprises to accept online and mobile payments. By opening up to different sources of funds transmission, customers are gaining new opportunities. The process itself affects the timeliness of payments and reduces the occurrence of errors.

Railwaymen creates solutions based on the idea of open banking

Open banking is a financial system in which banks and other financial institutions make their data and services available to third-party developers through APIs (Application Programming Interfaces). This allows developers to create new financial products and services that can be accessed by consumers through their bank accounts or other financial accounts.

In the next few years, modern finance is expected to be influenced by solutions that rely on open banking. Through this technology, seamless integrations can be made and existing processes can be streamlined. FinTech applications which make use of open banking are solutions that more and more financial institutions are interested in developing. Stand out from the competition and bring more value to your users by integrating your app with open banking.

Knowledge & Expertise in the UK financial system

We have a considerable track recording completing FinTech projects for companies in the UK. Thanks to our experience with previous implementations we have grown to know the realities of the British market and its local legal restrictions. We have also worked on integrations with British financial institutions, a great example of which is the HMCR certification we obtained while working on the FreshPay project. Moreover, our solutions meet the PCI DSS security standards related to handling branded credit cards.

In addition to our extensive experience in the UK market, our FinTech solutions are also commonly used all around the world. Our strength is that we are able to quickly and effectively adjust our solutions to local regulations and integrate with government systems regardless of the market the application is meant to operate in.
