What is a mobile wallet app?
A mobile wallet app is a digital application that allows users to store, manage and use their payment information for transactions on their mobile device. This app essentially turns a mobile device into a digital wallet, allowing users to securely store their credit/debit card information, bank account details, and other payment methods.
With a mobile wallet app, users can make payments, transfer money, and manage their financial transactions without having to carry physical cash or cards. Mobile wallet apps also typically provide additional features such as loyalty programs, coupons, and budgeting tools to enhance the user experience.
How to create a mobile wallet app?
Developing a mobile wallet is a complex process that requires a range of technical skills and knowledge, including expertise in software development, security, and financial systems. In this guide we consider these steps from idea to launch that will tell you how to make a wallet app.
Before beginning to design and develop a mobile wallet app, it is important to define the purpose and objectives of the future mobile app. This should include a clear understanding of what problem the app is trying to solve, and what specific benefits it will offer to users. This information will help guide the design and development process, and ensure that the app meets the needs of its target audience.
Compliance with legal requirements and standards
To create a reliable mobile wallet, it’s essential to ensure it is compliant with all the regulations. First of all, the software must comply with financial regulations such as Anti-Money Laundering (AML) and Know Your Customer (KYC) laws. Secondly, as the mobile application accepts, processes, stores, or transmits credit card data it must maintain compliance with Payment Card Industry Data Security. It is also important to ensure that the app adheres to all relevant laws and regulations in the country or region it operates in, including licensing, taxes, and other legal requirements.
Another important step is market research, as it provides valuable insights into the competitive landscape and user preferences. This research should include an analysis of similar mobile wallet apps, as well as an understanding of the broader digital payments industry. This step can help you understand what potential users are looking for in a mobile wallet app. This can include features like security, ease of use, and integration with other apps.

Choosing a design approach
Creating wireframes and prototypes
Once the design approach has been chosen, the next step is to create wireframes and prototypes of the mobile wallet app’s user interface (UI) and user experience (UX). Wireframes are low-fidelity representations of the app’s interface, while prototypes are more interactive and closer to the final product. These design elements should be tested with real users in order to ensure that the app is intuitive and easy to use.
User experience design
User experience (UX) design is an important aspect of the mobile app’s design phase. This includes the overall look and feel of the wallet app, as well as the flow and functionality of the various app’s features. User testing should be conducted in order to ensure that the app is user-friendly and meets the needs of its target audience.
Front-end and back-end development
The development phase involves building the app’s front-end and back-end. The development team should work closely with the design team to ensure that the final product is consistent with the wireframes and prototypes.

Consider key mobile wallet features
Another crucial step in creating an outstanding digital wallet is to implement necessary end-users features. It may be an informative transaction history, valuable rewards or convenient budgeting trackers. For example, with SDK.finance mobile wallet software you can provide users with expense tracking, helping them control their spendings.
Integration of payment gateway
This step includes the integration of a secure payment gateway, as well as features such as encryption, two-factor authentication, and fraud detection. This may include integration with third-party services or APIs, the development of additional payment methods, or other features that enhance the app’s overall value proposition.
To create a wallet app you must use robust security features in order to protect the users’ personal and financial information. The mobile wallet app can use biometric recognition ( fingerprint or face ID), or two-factor authentication that helps to prevent unauthorized access to your account.
Encryption and tokenization are two key security features used by mobile wallet apps to protect users’ sensitive payment information. The tokenization of payments is the effort to replace sensitive data, such as credit card numbers and PINs, with a unique identifier that can only be authenticated, decrypted and translated by the token provider.

For example, when the user makes a payment with the mobile wallet application, the tokenization service provider creates a unique token or identifier for the card information, which is stored securely in its database, making transactions more secure.
Quality assurance and testing
Prevention is better than cure, that’s why thoroughly software testing is one of most important steps in mobile wallet creation. Quality assurance and testing are critical aspects of the development phase, because they help to prevent any bugs or technical issues.
In addition, you can use different types of testing to provide the users with a reliable mobile wallet. First of all, functional testing to check if the app works as intended, including the user interface, navigation, and transaction processing. Second step is security testing that includes testing for vulnerabilities such as data breaches, hacking, and fraud prevention.
It is also essential to conduct the performance testing that helps to verify if the app can handle different levels of traffic and user loads without crashing or slowing down. Moreover, testing provides feedback and insights that can help companies improve the mobile wallet. For instance, the SDK.finance mobile wallet platform is tested with JUnit, Arquillian and checked with OWASP security scanner. Our technical team checks the code quality with SonarQube, UpSource and FindBugs.
Launch the application
Launching a mobile wallet app requires careful preparation and planning. This includes developing a marketing strategy, creating promotional materials, and preparing the app for distribution on app stores. The app should be submitted for review well in advance of the launch date in order to ensure that it meets all app store guidelines and requirements.
Ongoing development and support
Maintain and update a mobile app
After the mobile wallet app is launched, it is important to continue to maintain and update it in order to keep it running smoothly and provide ongoing value to users. This includes fixing any bugs or issues that arise, updating the app’s functionality and features, and ensuring that the app remains compatible with new operating systems and devices.
Get insights and optimize
Analytics and user feedback are valuable tools for measuring the app’s performance and identifying areas for improvement. Wallet app analytics can provide insights into user behavior, engagement, and retention, while user feedback can help identify areas where the app can be improved or expanded.
