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 2021 and 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 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.
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.

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.

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 payments contribute 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.

Developing a digital wallet can be a challenging process that requires the necessary knowledge, expertise and preparation. With SDK.finance creation of a payment product on top of our software involves several steps:
This step involves configuring environments, such as development, pre-production, and production, to ensure a smooth and efficient development process. It also involves setting up services that will aid in the deployment, monitoring, and maintenance of your e-wallet platform. By taking the time to configure these components correctly, you’ll create a strong foundation for the success of your e-wallet platform.
SDK.finance infrastructure consists of 3 servers: developers instance (for development and testing of the software); production instance (live operation server with end-users and real operations); pre-production or Sandbox (infrastructure with the same specs as the production instance used for debugs of integrations with third-party components).

RAM – 2 GB
SSD – 40 GB
OS: Ubuntu 20.04 LTS
Software: NGINX 1.14.0
Creating roles, setting up commissions, creating wallets, currencies, contracts, setting up exchanging rates and permissions.
To start configuring SDK.finance digital wallet software you need to authorize as an administrator via API. In the response, you will receive a token along with the other user’s parameters. The received token should be used to access other APIs. You can also save any other parameters if needed.
Then you can create any system currencies( real or any objects which you are going to count in your e-wallet platform like points, coins, bonuses, etc.) First, you have to create an issuer and the system will generate an id which will be used in the use cases where it is required to specify the currency.
To enable currency conversion within the digital wallet, it is essential to establish exchange rates. This can be achieved by either manually managing the exchange rates or integrating a reliable third-party service.
For instance, SDK.finance leverages the powerful Currency Cloud service for obtaining accurate and up-to-date currency exchange rates. Check our knowledge base to find out more information about currency exchange commission calculation.
SDK.finance offers implemented basic top-up and withdrawal flows that can be extended and customized based on our client’s business needs. You can configure top-up via:
There’s also a pre-developed flow for top-up by cards, which is available on the UI, but will be fully functional after integration with a certain third-party provider which will cover this functionality.
Users can conveniently withdraw funds from their wallets through the methods activated for their types of contracts:
• via external provider (to the card, to third-party provider, directly to bank account, etc.)
• to bank account via bank transfer
• via cash desk
Check our knowledge base to get more details about top-up and funds withdrawal.
