The fundamentals of a mobile banking application

Banks are facing increasing competition and rapid changes in their customers' habits. According to a Business Insider Intelligence’s study, 89 % of respondents said they currently use mobile banking. Therefore, to remain competitive and meet their needs, banks must offer reliable and user-friendly online and interconnected banking services.

Mobile banking applications are an important way for banks to engage with their customers and provide them with instant access to their accounts, allowing them to manage their finances efficiently and conveniently.

In addition, mobile banking apps can also offer additional features such as real-time notifications, spending alerts, and budgeting tools, which can help customers make informed financial decisions.

In short, these applications are essential for banks wishing to provide a quality customer experience and remain relevant in a constantly evolving market.

Let's take a look at the essential features that a mobile application must have to be comprehensively useful for users in their daily banking activities.


What are the essentials in which we need to think about when doing a mobile banking app?

5. Strong Customer Authentication: reliable security in all transactions

Mobile banking transactions require a trustworthy and secure authentication for all end users. In that way they will feel confident to make payments, transfers and other transactions through the digital channel offered by the bank.

Within the application, this strong authentication system must be so well integrated that the user can execute it easily, smoothly and quickly. At this point it is also important that the bank provides an authentication and securitisation solution that is compliant with European and local regulations (PSD2, EMVCo, eIDAS, GDPR, ...) in order to optimise the customer journey while providing a high level of security.



Mobile banking applications are established as another channel of connection with the user, but above all as an additional presence of the bank, accompanying its customers in their daily banking activities, such as helping them to make informed financial decisions and providing them a way to execute selfcare operations, like loan applications, e-signature for contracts, etc, providing a secure, quality service that meets the user's expectations. At the same time, a well-structured mobile banking application provides multiple benefits for the bank, among which we can find savings in response times to requests and problem handling, improving its image with its customers and staying ahead of market demands.

Overall, well-built mobile applications are essential for banks looking to provide a quality customer experience and stay relevant in a constantly evolving market.
