Digital Wallet App Features

Transaction History and Notifications

Your app should provide users with a detailed history of their transactions, reflecting their past payments and purchases. Also, enable push notifications and email alerts to inform them about their account activities.

Transfer Money to/from the Bank Accounts

Mobile wallets must enable seamless money transfer feature from one bank to another bank account and from eWallet to bank account and vice versa. The process of transferring money in and out of the wallet should be extremely easy, secure, and convenient.

Bill Payments

Your eWallet must facilitate users to pay their utility bills online, such as electricity, gas, mortgages, rents payment, etc. To make it secure and successful, you need to partner with multiple third-party service providers in the category to give users an easy payment option.

Management of Virtual Cards

The wallet application should enable users to save their debit and credit card data ensuring high security practices like PCI-DCC and so on. It should allow people to add money to their wallets through a one-click system. Moreover, users should be allowed to remove or add cards to their lists.

Contactless Payments Method

Contactless technologies like QR codes and NFC are becoming extremely common in retail chains. Considering their growth, it can be very profitable for your digital wallet to facilitate contactless payments in physical stores, making transactions quick, easy, and convenient.

Secure Authentication

Security should be your prime priority when developing a fintech app. Thus, don’t miss out on implementing robust user authentication methods such as PIN generation, fingerprints, facial recognition, and even two-factor authentication. It ensures that only authorized users can access your app.


To ensure the success and accessibility of your digital wallet for all genres, you should allow the easy self-registration process so that the maximum number of users can enjoy your offerings. Usually, the self-registration process follows the following steps:

  • Download the application
  • Follow the KYC process
  • Confirm registration through OTP
  • Set up the password and login
  • Link cards
  • Add money to the wallet.

Rewards and Discounts

Rewards and discounts are the lucrative aspect of your eWallet that tempt the users to use the app for the maximum of their financial activities, which leads to increased engagement and retention rates. 

Analytics-Based Dashboards

The mobile wallet must have a user-centric dashboard that gives detailed information about their spending habits, upcoming bills, etc. You can even introduce a budget management and expense tracking module in the application.


Integrating a chatbot that provides 24/7 support and gives quick responses to all customers’ queries is one of the most remarkable trends in today’s tech-driven world. So, don’t lag behind in leveraging this AI trend. You can go the extra mile and even implement voice search features in the app.

Multi-Currency Support

If your eWallet caters to the global audience’s needs, you must consider offering multi-currency support. This feature enables easy transactions and conversions for international users.

Peer-to-Peer (P2P) Payments

P2P payment is one of the most used digital wallet features that allows users to send and receive money directly to/from their contacts using their eWallets. This feature is particularly useful for splitting bills or paying back friends. PayPal is one of the most quoted examples in this category, with millions of people using it to transact for both personal and professional reasons like paying for outsourcing, etc.

Digital Wallet App Development Process: Step-by-Step Guide

Building a secure eWallet comprises the same method as any other mobile app development process, such as UI/UX designing, payment integration, development, deployment, etc. Let’s discover each phase in detail:

Digital Wallet App Development Process

Define Your Product Goal

The first step to your digital wallet app development process starts with defining your product goals and specifying what features it will have. For instance, do you want your application to store multiple currencies, transfer money, make payments to merchants, pay bills, or do other activities? Make sure to clearly define your goals before moving on to the next step.

Design an Intuitive Interface

Once you have defined your product goal and features, it is time to create a user-friendly UI/UX design with which your customers will interact. According to a report, 90% of users lose their trust in an app and discontinue its use due to a poor experience. Hence, creating a visually appealing and easy-to-navigate interface that allows users to access their accounts quickly, transfer funds, and make payments, is essential for successful eWallet app development.

Implement Security Measures

Security is a prime concern when developing a FinTech app, and a digital wallet is no exception. Therefore, you must integrate robust security measures like biometrics to prevent data breaches and reduce the risk of cyberattacks when developing an eWallet.

Develop the Digital App

Now comes the most critical and technical aspect of the process – development. Depending on the UI/UX design and your user base, set up continuous integration and continuous deployment (CI/CD), integrate essential features, and deploy technology stacks to ensure your product behaves as it should.

Test and Deploy Your App to the Market

Before submitting your digital wallet to the app store and bringing it to the end users, thoroughly test it for functionality, security, and usability. It includes testing for bugs, errors, glitches, vulnerabilities, and performance. After testing and iterating the application, it is time to launch your app to the market.

To be a successful eWallet company, you must adhere to the essential regulatory compliances as per your country’s specific laws and guidelines.

Security Compliances for Digital Wallets

Data Privacy Regulations

To protect users’ personal and financial data, you should comply with essential data privacy regulations. Some of the most common data privacy compliances are California Consumer Privacy Act (CCPA) and the General Data Protection Regulation (GDPR).

Multi-Factor Authentication

It would be best if you implement multi-factor authentication to add a layer of protection to the application. For instance, an iOS app development uses face recognition, pin, and password to validate users’ authentication.

Secure Data Transmission

In the ever-evolving digital world, you must secure data when at rest and in transit. To provide your users with a secure data transmission experience, you should use secure communication channels such as SSL/TLS/VPN to encrypt all data transmissions between the app and the server.

Secure Data Storage

To secure users’ sensitive information and financial data, such as credit card details from fraudulent activity and unauthorized access, you should implement secure storage methods such as encryption and hashing.

Protection Against Fraud

Mobile wallet app development should include features that detect and prevent fraudulent activities such as unauthorized access, transaction monitoring, and suspicious activity reporting.

PCI-DSS Standards

To ensure secure processing of credit and debit card information, your eWallet should comply with payment card industry data security standards.

Regular Security Audits and Updates

With the ever-increasing risk of data breaches and cybercrime incidents, your mobile wallet app should undergo regular security audits to find out any vulnerabilities and implement timely security measures.

By considering these security compliances, you can create a secure and successful eWallet that instills confidence in users.

What are the Different Types of Mobile Wallet Apps?

There are multiple types of eWallets that address specific business models and target users’ needs depending on their device’s operating system and location. For instance, Google Pay is the most popular choice for Android users, while iPhone users consider Apple Pay. Others rely on PayPal as it offers international-level acceptance. Furthermore, Cash App and Venmo work only with a US phone number. We can segment these applications into the below-listed categories of eWallets:

Types of Mobile Wallet Apps

Closed Wallets

These wallets are specially designed for a merchant that sells products or services, allowing users to use the wallet for that particular merchant only. For example, an eCommerce app enables you to store money in the app’s wallet and use it to pay for an item in the cart. Starbucks, a leading multinational chain of coffeehouses, is a good example of a closed wallet.

Semi-Closed Wallets

A semi-closed wallet allows users to use funds in their wallets to make payments for transactions on websites or apps their merchant has partnered with. Paytm can be a great example of a semi-closed wallet.

Open Wallets

Open wallets such as PayPal are used directly in a third-party application or in a bank app to support any type of transaction. It enables customers to send and receive online and in-store payments, transfer funds to their bank account and keep them in their wallet for future use. Open wallets require both receivers and senders to have accounts on the same application.

Crypto Wallets

Cryptocurrency wallets are designed to store, sell and buy cryptocurrencies. These wallets store the public and private keys of users to facilitate transactions over their applications. The best thing about crypto payment wallets is that you can design them as per your specific needs – closed, semi-open or open.
