How To Develop Mobile Banking App?

How to build a mobile banking app? Banking mobile app development involves several major stages to ensure its success, security, and functionality. Here are 8 major stages involved in developing a mobile banking app:

Step 1: Market research and analysis

Before starting the mobile banking application development process, it is crucial to conduct market research and analysis.

This initial step enables you to identify the market’s leaders, study the competitors, and understand the market’s needs. By that, you can define your winning spot in the market, and compile differentiating specifications for your application.

This stage usually takes a month or two. As the result of the research step, businesses will get:

• User persona profile;
• Market analysis;
• Market share;
• Market habits;
• Competitor’s strengths and weakness;
• Value proposition.

Step 2: Provide the security base

Privacy and security is the factor that your users care about the most when it comes to mobile banking applications. Ensuring proper compliance and security guarantors can also become your unique strength that differentiates your app from others.

Users will never put faith in using a mobile banking app with weak security. Therefore, you should be very careful about all the security bases before mobile app development starts, such as:

• Safe passwords: Passwords should be stored securely in the database, using a special method to protect them.
• Automatic logout: If a user doesn’t do anything for a while (let’s say 15 minutes), they should be logged out of the app automatically, both from the front and back ends.
• User data privacy: When creating a banking app, only a few people should be able to access important things like tokens and passwords. So, keep all the data in one safe place.
• Security certificates: Ensure you have an SSL certificate for a web app. For a mobile app, use SSL pinning. These things make sure that data is kept private when it moves between the app and the server.
• Secure authentication: Use fingerprint security for Android and Apple keychain for iOS to make sure only the right people can get into the app.
• Safe card information: Use VGS (Very Good Security) to show customer card details securely.

Besides that, mobile banking app development companies have to follow a bunch of rules depending on where they are. Some famous ones are PCI DSS, CCPA, GDPR, PSD2, and SEPA.

Depending on where you are, there might be more or fewer rules for your online banking app. So, ask your legal and software teams to check this out for particular markets or nations.

Step 3: Develop and test a prototype

Before building the complete mobile banking app, you need to create a prototype/ or an MVP version illustrating the app’s structure, visuals, and logic.

A prototype serves as a valuable tool for testing your concept, confirming its suitability for the market, and avoiding excessive spending on an idea that may not turn out well.

To ensure that the prototype accurately represents the future product’s functionality, you should undertake several essential tasks:

• Interview with the product owner: During this phase, the designer engages in a discussion with the individual responsible for the product, seeking clarity on their expectations and requirements.
• Utilize user stories: Typically, a multitude of user stories exists, following a standardized format such as: ‘As a <role or user type>, I want to <perform an action> in order to <achieve a specific outcome>.’
• Embrace job stories: This approach focuses on understanding user needs by employing the formula: ‘Given a certain situation, a user is motivated to achieve a specific result.’
• Explore jobs to be done: This comprehensive study defines the scope of upcoming work and assists in crafting a product that comprehensively fulfills user needs.
• Ask for feedback: To seek valuable feedback, you can use methods like surveys, interviews, or having people test your prototype. The goal is to gather insights and suggestions that will help you refine your prototype and make it the best it can be before turning it into a final product.

Step 4: Design the UI and UX

The UI/UX design phase will kick off using the information collected during the research phase, including insights from user interviews and feedback on the prototype.

In this stage, the project owner creates detailed wireframes and mockups that provide a visual representation of the app’s layout and user journey. This process aids in fine-tuning the app’s design and features before the mobile banking app development phase:

• Design a user-friendly and visually appealing UI: Invest in designing an intuitive and visually appealing user interface (UI) that aligns with your brand identity. Consider user accessibility and readability in your design choices.
• Focus on intuitive navigation: Prioritize user-centric design by ensuring that navigation within the app is straightforward and logical. Users should be able to accomplish their tasks with minimal effort and confusion.

Step 5: Develop the app

The mobile banking app development phase is where most of our time will be invested. This is when our banking app developers transform the prototype into a fully functional app.

At the beginning of the development stage, you choose a specific type of mobile app development approach: whether to go with a native development approach (developing separate apps for iOS and Android) or cross-platform development. This choice significantly influences the timeline and resource allocation for development.

So how to create banking application in android or iOS? When it comes to mobile banking app development, the choice of technologies primarily hinges on the platforms or operating systems we opt for. Let’s take a closer look at the technology requirements based on different platforms:

• For cross-platform development: Flutter; React Native; Xamarin
• For hybrid app development: Cordova/PhoneGap; Ionic
• For iOS development: Objective-C; Swift; Xcode IDE; Appcode; UIKit; SwiftUI
• For Android banking app development: Kotlin; Java; Android Studio and Android Developer Tools (ADT); Jetpack Compose, or you can use branded Android UI software

To ensure that the product aligns closely with your expectations, it’s crucial to maintain regular communication with the development team and provide ongoing feedback. This practice minimizes the number of edits and accelerates team workflows.

Depending on the complexity of the features, the mobile banking app development process typically spans from three to six months and comprises two main phases:

• Develop the backend infrastructure: Establish a robust backend infrastructure capable of handling data storage, security, and communication with external systems and services. Implement server-side logic for processing transactions and managing user data securely.

• Implement core features: Build core features like user authentication, account creation, account management, and basic transaction functionalities. Ensure these features work seamlessly.

Step 6: Integrate 3rd parties

In the process of mobile banking app development, incorporating third-party integrations can be highly advantageous. The integration of third-party APIs, such as those for payment processing, account linking, and real-time market data, can greatly enhance the user experience and captivate customer engagement to the maximum extent.

When selecting a third-party integration service, the most critical factor to consider is its stability, security, and dedicated support.

Step 7: Testing before release

To ensure your mobile banking app development achieves peak performance fulfills its original objectives, and maintains robust security, you’ll need the help of QA specialists to:

• Conduct rigorous testing: Perform thorough testing to identify and address both functional and non-functional issues. Test the app’s functionality, user flows, and responsiveness across various devices and screen sizes.
• Perform security testing: Conduct penetration testing to identify vulnerabilities and security weaknesses. Ensure that user data is protected at all stages of data transmission and storage.

Step 8:  Release, maintain, and improve

Following successful testing, the product is officially launched and is backed by a team of specialists. This ensures that any technical problems that may arise are promptly eliminated.

As the client’s business expands and market demands evolve, the need to enhance and enrich the application with additional features is essential. New marketing research will help you determine potential areas of improvement or optimization (see Step 1). Thus, the entire software development process can be considered a continuous cycle.

Mobile Banking Development Challenges

Mobile banking app development can be a complex and challenging process due to the sensitive nature of financial data and the need for a seamless user experience.

According to the experience of many of our colleagues, here are the top 5 challenges faced by developers in this domain:
