The digital payment market is constantly growing. It is expected to reach $16.59 trillion by 2028, showing a CAGR of 9.52% between 2024 and 2028. 

As users and businesses alike tend to opt for the convenience and security of digital payments, the demand for reliable digital wallet apps is on the rise. A digital wallet is a software application on an electronic device that can be used for making payments without cash or plastic payment cards. Google Pay, Cash App, and Samsung Pay are just a few examples of digital wallet apps.

Here is our guide on how to undertake mWallet app development using ‘software development kits’ (SDKs). In this guide, I will mention a few SDKs, so that you can make as an informed choice as possible. Make no mistake, this is a full-fledged development project, however, SDKs will likely make the job a bit easier. I will explain the mobile backend aspect after I describe the SDK options.

Digital wallet application development — SDK options

SDK option #1: Mastercard Mobile Payment SDK

This SDK is from the giant financial services company Mastercard. The SDK includes a library of tools to help with the process of building a mobile wallet app. Additionally, it has a sample app, and also includes a testing simulator.

The Mastercard SDK supports solutions for the Mastercard Cloud-Based Payment (MCBP)-specifications only. This app will support in-store transactions as well as mobile online transactions.

You can develop Android apps using this software. Firstly, you need to sign-up for the Mastercard developer portal. View their SDK documentation. Explore their quick start guide.

SDK option #2: PayPal Mobile SDKs

These SDKs are offered by the financial services giant PayPal. Their Braintree direct SDKs allow you to build both Android and iOS apps. You can access the Braintree GitHub iOS SDK documentation and Android SDK GitHub documentation for Braintree. You can also check out the complete Braintree payment SDK documentation.

Remember that mobile payment regulations vary from country to country. While in some countries, it is acceptable to use Braintree, in some other countries an alternative method is required. For such scenarios, PayPal also offers their Checkout integrations. Visit the ‘PayPal Developer’ portal for their complete API documentation.

SDK option #3: Simplify Commerce mobile SDKs

Simplify Commerce mobile SDKs allow you to build mobile wallet apps for Android, iOS, and ‘Apple Pay’. These are offered by Simplify Commerce.

With the Simplify Commerce Android SDK, you can develop a mobile wallet for Android. The SDK documentation provides step-by-step instructions. The instructions include steps to use the Google Pay API.

You can create a mobile wallet app for iOS with the Simplify Commerce iOS SDK. Check out their API documentation and iOS ‘Apple Pay’ SDK documentation.

SDK option #4: QuickPay mobile SDKs

QuickPay, the UK-based payment service provider offers mobile wallet SDKs for Android and iOS. Credit cards, mobile payments, etc. are commonly accepted payment methods. You need to sign-up for QuickPay.

Access their mobile SDKs. You can view their complete API documentation. While they offer a free test account, you need to select one of their paid plans for processing real transactions. Check out their pricing plans. Their pricing plans include integrations, fraud filters, virtual terminals, and subscription features.

SDK option #5: Razorpay mobile SDKs

Offered by Razorpay, an Indian provider, this solution only works in a handful of countries but is a great example of a mobile wallet. If you are planning to take advantage of the fast-growing Indian mobile payment market, or like their approach, the Razorpay Mobile SDK is a good option for you.

The company offers two major features. Firstly it allows for two-factor authentication which adds an extra layer of security. The platform also regularly updates its APIs to remain as cutting edge as possible. For more on this and to access their SDK and API documentation, head to the Razorpay Developer Hub.

Hosting your mobile wallet app backend

In this guide on how to make a digital wallet app, we will also examine options on where to host the mobile backend. I recommend that you use a ‘Mobile Service as a Backend’ (MBaaS) provider when you build a mobile wallet app. It saves you crucial mobile backend development and management effort. You get a quick ‘Time to Market’ this way.

There are several MBaaS providers, and the following are a few examples:

However, the mobile wallet business is a highly regulated one, besides, regulations vary across countries. Depending on where you are launching your app, you may need to ensure that the data remains within the borders of the country.

In such cases, you may not be able to use the public cloud straight away since the servers may reside outside that country. You may need to explore a hybrid cloud solution, alternatively, you may need to rely on a private cloud. Therefore, you must engage a cloud service provider.

Following are a few reputed cloud service providers:

Managing your mobile wallet application development project

While SDKs and MBaaS providers can make the development a bit simpler, it’s still a complex application development project. You need to manage it end-to-end. Let’s start with building a team.

Building a mobile wallet app development team

You need to build a team with the following skills:

  • Business analyst.
  • UI/UX designers: Note that UI gives the first impression to your users, hence, it must stand out. Designers should know modern mobile navigation designs well. Consult our article “Mobile Navigation Menu Examples”.
  • Mobile developers:
    • Android developers.
    • iOS developers.
  • 1 project manager.

The complexity of your mobile wallet app and your delivery schedule will determine how many designers, developers, and testers you need. You need to get a project manager with adequate knowledge of modern project management methodologies. Check out our guide “What are the Top Project Management Methodologies?”.

A mobile app is a ‘System of Engagement’ (SoE). ‘Agile’ is a good methodology for SoE development, hence, I recommend that you use it. Check out our guide “How to Build an Agile Development Team?”.

Mobile wallet app development project execution and tracking

I recommend that you use the ‘Scrum’ technique since it’s a well-developed technique within the larger ‘Agile’ methodology. In this approach, you divide your project into ‘Sprints’. You first build a ‘Minimum Viable Product’ (MVP). It’s a functional product, with which you can get real market feedback. Subsequently, you will enhance the product and its features based on market feedback. You do this in an iterative fashion by undertaking multiple ‘Sprints’.

To execute a ‘Sprint’, you organize a cross-functional team. It’s a team consisting of business analysts, designers, developers, and testers. The PM should perform as a ‘Scrum master’. Read more about it in “How to Build a Scrum Development Team?”.

At first, you build a ‘product backlog’. This is the list of features you need in your mobile wallet app. Subsequently, you plan your ‘Sprint’, by estimating the features requested in the product backlog. This way, you can determine the content of a ‘Sprint’, i.e., which features will go in which ‘Sprint’. This is called ‘Sprint planning’.

When the work is in progress for a ‘Sprint’, the ‘Scrum master’ needs to be fully involved. To gather daily status from each team member, the ‘Scrum master’ needs to conduct a ‘daily stand-up meeting’. Here, each team member provides status, besides, issues and challenges are discussed.

After the work of a ‘Sprint’ is complete, you need to conduct a ‘Sprint review meeting’. This is where the team demonstrates the work. By this time, all features in that ‘Sprint’ should be ready. Once you get the feedback from the project stakeholders and they accept the features, that ‘Sprint’ is complete. However, you now need to conduct a ‘Lessons-learnt’ exercise, which is called the ‘Sprint retrospective meeting’.

To effectively execute and track such projects, you need to use relevant tools. There are quite a few project management tools available, like ‘Trello’, or ‘Asana’. Check out our guide “The Best Agile Project Management Tool of 2024” for more details.

How much does it cost to create a digital wallet?

MBaaS providers and cloud services providers provide detailed pricing plans. You can visit their website to get an idea of their price, however, you need to hire mobile wallet app developers. Your project complexity will determine the effort, whereas your geography influences the per-hour cost for developers.

Depending on your local labor market, some skills may be considered a premium. You may need a higher lead time for hiring, and more money set aside as niche skills come with higher costs. If you need help to assemble a team, consider engaging a development company like DevTeam.Space.

DevTeam.Space is an innovative American software development company with over 99% project success rate. DevTeam.Space builds reliable and scalable custom software applications, including digital wallet apps.
