How to Create a Digital Wallet: Key Features and Solutions

The global technology market has grown rapidly from $1,6 billion in 2015 to $14 billion in 2022, according to Merchant Machine. It is driven by the adoption of online payment methods for banking and financial services. Mordor Intelligence forecasts that mobile payments will grow 24.5% between 2021and 2026. The demand for an online mobile payment system increases the need for digital solutions. As a result, fintech companies are trying to provide a frictionless payments experience for their customers, and are pushing back against a product-centric approach. One such solution is a mobile wallet application that keeps credit cards and provides transactions.

However, developing the fintech software is a time-consuming and costly process. The cost of developing an e-wallet app varies from $45,000 to $250,000 and depends on the level of complexity and functionality of your wallet. Nevertheless, there is a solution that can speed up the process and reduce development costs.

In this article, we discover what an e-wallet is, how it works and what you need to know before developing such an app.

What is a digital wallet?

Digital wallets are computer software that can conduct transactions online or over the Internet. It stores customers’ payment details for different payment methods on different websites. Digital wallets are also referred to as e-wallets. Although digital wallets are often stored on smartphones, there is another form, such as on a desktop.

Digital wallets can enable more than just transactions. They also hold loyalty cards, tickets, gift cards, and are used for user authentication. For example, mobile wallet apps can verify a person’s age when purchasing alcohol.

How does a digital wallet work?

To use a digital wallet, the customer enters their card information into the app or on the digital wallet website. Once the device is unlocked and the information is encrypted, the wallet is ready to use. Then users need to hold their device near the contactless terminal in order to perform a payment.

To ensure a secure payment experience, digital wallets use various technologies, including near-field communication (NFC), magnetic secure transmission (MST), and QR codes. Typically, NFC is used by the customer’s device to communicate with the merchant’s payment terminal when making an on-site purchase. When the customer confirms the transaction with a password, fingerprint or facial recognition technology, secure transmission of payment information via payment tokenization completes the transaction.

For online payments, almost the same processing applies. The main difference is that the digital wallet is already installed in your browser or on your desktop and therefore doesn’t need to interact with NFC.

The process of payment processing includes the following steps:

1.The customer enters the card information into the app or onto the website. 

2.Then the information is encrypted and the wallet is ready to use. 

3.Once the user authorizes the transaction, the data is sent to the bank account that transfers the money to the merchant account.

The new online payment system offers a revolutionary alternative to cash payments. The user does not have to rely on a card for a transaction. All they need is a smartphone and an Internet connection. That’s why mobile wallets are becoming more and more popular all over the world.

Why do you need to invest in mobile wallet app development?

According to Statista, the market for mobile wallet transactions will grow significantly over the next few years. It is expected that the total number of digital wallet users worldwide is expected to exceed 5.2 billion in 2026, up from 3.4 billion in 2022, representing strong growth of over 53%, due to a new study from Juniper Research

As a result, the banking and financial sector is being forced to shift its key service and product offerings to digital formats. In response, financial institutions have started to offer various digital solutions tailored to specific needs. Thus, the introduction of digital payment options helps to increase customer loyalty, boost demand, and improve the convenience of modern users.

The basic technologies behind a digital wallet

Wallet apps can be used quite easily. The customer launches the app with PIN codes or fingerprints to select the card to use. Many digital wallet apps use NFC technology when transferring cards and can even be used to make purchases. 

NFC (or near field communication) is a contactless technology that provides secure transactions between a wallet and a POS terminal. It functions as a communication protocol and enables contactless payments via mobile devices.

MST (or Magnetic Secure Transmission) is a similar technology to NFC that uses magnetic card readers to scan your card when you swipe it through a slot on POS.

iBeacon enables secure data exchange that provides security authentication and the ability to send personalized offers and discounts to customers.

QR code contributes to a seamless payment experience. The transaction takes only a few seconds, making payment via QR codes extremely fast and convenient. Users just need to open the QR code scan app, scan the QR code and confirm to make the payment 

Biometric authentication enhances the security of digital payments and provides fingerprint, facial and voice recognition. It also prevents fraud and extortion.

Artificial intelligence and machine learning. Digital wallets must have AI and ML capabilities that help integrate admin panels and detect fraudulent activity.
