How to Build a Digital Wallet App

With the world swiftly transforming, digital wallets are the new banking norm, allowing customers to do so many things on the go.

Updated: 4/28/2022

The banking and financial sectors are going through a big digital transformation. Major US banks are shifting from tap-and-pay cards to digital wallets to make life even easier for their customers. The COVID-19 crisis has sped up the adoption of the digital wallet globally and its use worldwide is projected to spike at 70% by 2025.1

Services like Google Pay, Apple Pay, PayPal, Kakao Pay, and Samsung Pay, to mention just a few, are working on new digital products that will push the industry even more forward. Mobile commerce is expected to cover about 80% of all e-commerce transactions in value by 2025. The leading countries adopting digital wallets are Singapore, China and Hong Kong.

Essentially, the digital wallet is a digital service that benefits all sides: it helps banks save the money spent issuing physical cards and gives customers a more convenient way to manage their money on the go.

Fueled by the Pandemic: Rise of Digital Wallets in 2022 

COVID-19 heavily influenced digital payment development across the world. In particular, the US saw a greater increase in NFC payments than any other country 

Nearly 60% of the world’s population will use mobile wallets by 2025

Many Americans tried out mobile payments for the very first time during the pandemic. The early adopters of digital payments were younger generations, including millennials and Gen Z, but this technology is quickly on the rise for the US population as a whole. 

While NFC is the most common type of mobile payments, there are myriad other mobile wallets used in physical stores, online, and for QR code payments.

Apple Pay remains the dominant mobile payment platform, with 43.9 million users in 2021. Between 2020 and 2025, it is predicted that there will be an additional 14.4 million users, creating a significantly bigger gap between its competitors. Unsurprisingly, the growth of Apple Pay’s market share might also increase its lead in the next few years.

Starbucks managed to beat out Google Pay and Samsung Pay with more users for POS transactions. In 2018, Apple Pay and Starbucks had similar numbers, but Apple Pay was able to overtake the market lead in the past three years. 

Google Pay and Samsung Pay are showing stagnation, although their positions remain strong through 2021 and 2022.  eMarketer research shows that with the increase in mobile wallet usage, the average annual spend is also growing, as annual spend per user rose by 23.6% in 2021, and is on its way to rise by an additional 33.3% by 2023.

What’s to Know About Digital Wallets?

A digital wallet is a payment service that stores an individual’s information about their debit and credit cards. It in fact contains not just debit and credit cards but also loyalty and membership cards, so a person can access all of them while shopping.

While some wallets simply store debit and credit card information, others are more versatile, enabling holders to complete P2P transactions and access additional financial services.

As the global mobile payment market develops, it’s becoming obvious how much the digital wallet can offer various industries. For retailers, it’s convenience, speed and increased security for holders. Those same benefits apply to telecoms companies, big financial institutions, and many other sectors.

Finance

Banks and other services providing individuals with prepaid, credit or debit cards will find digital wallets a useful feature or add-on to their online banking apps. Offering a digital wallet could give banks access to personal information that will make it easier to conduct customer checks and other regulatory actions.

Retail

Digital wallets are a great addition to mobile apps in retail and an important part of the mCommerce landscape. The growth of mobile commerce skyrocketed as mobile platforms began making it possible for customers to shop using digital wallets. Moreover, retailers can use digital wallets to store information about sales, coupons and loyalty cards, or just to notify customers when a sale starts.

Telecommunication

As technology progresses, telecoms have become more flexible and responsive to their customers’ needs. Since all of these providers operate services for mobile devices, the digital wallet has become a great solution to their customers’ changing needs.

2.8 billion people use mobile wallets it's projected to rise to 4.8 billion users by 2025 02

5.    Mobile payments through tap-and-pay technology or wallet QR
6.    Access to different payment models

Digital Wallet Types

Every digital wallet app is directly connected to mobile communication service providers, financial institutions, or banks, and the core function of every wallet application is related to payments.

The Basic Technologies Behind a Digital Wallet

Wallet apps are fairly simple to use. The customer opens the app, uses a PIN code or fingerprint, and chooses the card they plan to use. Most digital wallet apps use NFC technology to transfer card information and complete a purchase.

Technologies Behind a Digital Wallet

Simplicity of design is important with any digital wallet as it provides frictionless, easy-to-use transactions. The smoother the experience, the higher the adoption rate for a variety of users. With an intuitive product design, it’s easier to navigate the wallet, find the right function, and incorporate that feature into everyday payment practices.

NFC. Contactless technology plays a major role in providing secure communication between smartphones and POS devices. The technology is somewhat similar to Bluetooth, but it has a shorter connection setup time, with three fields of application in payments: card emulation, reading mode and P2P mode.

Bluetooth and iBeacon. Most smartphones already support iBeacon or Bluetooth technology. iBeacon also allows merchants to send personalized offers in various advertising campaigns and discount coupons once they are in the range of radio beacons.

QR codes. QR codes have become the norm for a variety of services. What’s more, merchants are adding QR codes to every bill to ensure a seamless payment experience.

Digital Wallet Security

Another key component of any digital wallet is a high level of security for every transaction. Holders want to know their money is safe, and you can ensure it by offering P2P encryption, tokenization, and passwords.

Point-to-Point encryption (P2PE). P2PE is an advanced tool that protects transactions. It starts encrypting transactions when you swipe your phone over the POS terminal: your transaction is then in transit and needs to be authorized. This type of protection has to be included in the security features of every digital wallet.

Tokenization. This technology uses a reliable data encryption system to ensure the security of every e-payment. All card information gets encrypted and turned into tokens.

Passwords. One of the best-known ways of protecting personal data is through passwords. A strong password is key to increased protection levels and makes digital wallets more secure.

The Future of Mobile Payments

About 2.8 billion mobile wallets were active worldwide at the end of 2020, and that number is expected to jump by 74%, reaching 4.8 billion in the next five years. While digital wallet usage in North America is on the rise, overall adoption of e-payments is lagging in the US compared to China and other parts of Asia. This is the main reason why AliPay and WeChat Pay are still the dominant mobile wallet providers globally.

The consumer mindset around the use of mobile payments is changing rapidly. As payment innovation continues to make mobile payments more secure and as businesses continue to make it easier to use and integrate mobile payments, it’s expected that adoption will continue to rise. By 2024, digital wallets are projected to grow an additional 38.2% over 2020 levels, and will account for 40.5% of North American e-commerce payment volume.

It’s clear that mobile payments are poised for growth in the U.S. Both B2C and B2B mobile payments adoption will continue to expand, and companies will continue to integrate mobile payments as part of their payments mix. 

However, it is user experience that will ultimately drive overall adoption. As companies who haven’t adopted this technology begin to see the benefits mobile payments provide customers and employees, they won’t be far behind on the adoption curve.
