Since its inception eight years ago, the Unified Payment Interface (UPI) has been a transformative finance technology that has enhanced convenience and hassle-free payments to users, not to mention streamlining bank transactions. The UPI is an Indian real-time payment system that facilitates easy, cost-free money transfers between bank accounts in real-time via a mobile device. The technology efficiently eliminates the need to carry cash, which expunges the risk of carrying cash and does away with the time-consuming process. How is such an innovative technology developed? Read on to find out.
Necessity spurns invention, and it is from this heuristic that the UPI system was innovated. The body responsible for the development of the UPI is the National Payment Corporation of India (NPCI). NCPI was established in April 2009 to integrate and standardize India’s payment systems for all retail transactions. Noticing that over 145 million families had no access to any form of banking, not to mention the intention of the government to curb black money transactions, the NCPI committed to developing a safe, efficient, accessible, inclusive, interoperable, and authorized payment and settlement system in India.
The UPI has remained reliable in achieving most of the initial objectives laid out by the NCPI. The UPI has successfully affected efficient transactions that are interoperable between banks and are safe since the authorization of any transaction is wholly dependent on user input. But how does this technology work? The Unified Payments Interface (UPI) combines many bank accounts into a single mobile application that supports UPI. It does this by combining several features from any bank that is a participant, making financial transfers easy for both consumers and businesses. UPI uses the PUSH and PULL mechanisms, respectively, for money transfers.
The users use an app that supports UPI and choose the Pay or Send option to send money. The recipient selects the bank account or wallet from which the funds will be debited after providing their information, including their UPI ID or cellphone number and the requested amount. After entering the UPI pin to finalize the transfer, the transaction request is sent to their chosen PSP. The recipients must log into the UPI-enabled app and select the “collect or request money” option to receive money. After entering their desired amount and Virtual Payment Address (VPA), the payer chooses the bank account to which they want the funds to be credited. The payer receives a money request message, which they enter into the UPI PIN to authorize the request.
The transaction is processed in real time between the banks, and the crediting and debiting are instant. In addition to applying the Two-Factor authentication, the UPI system integrates biometric authentication using technology such as fingerprint and facial recognition to authenticate transactions and further the platform’s security. An additional safety enhancement feature in the app is phone number verification. Verifying your mobile number is a step in the registration process on the platform. After that, this number will become an identity since it will be connected to your UPI account. Verification will have to start over each time one changes their phone number.
As with developing other finance tech applications, developing the application with UPI integrated follows a similar path. First, one needs to define the scope within which the application will operate. The UPI payment software aims to offer a complete platform for safe and easy online transactions. It provides functions including bill payment, in-app purchases, and fund transfers. The scope includes interaction with many banks and financial institutions, multi-platform compatibility (iOS, Android), and user-friendly interfaces. The app has security features, such as end-to-end encryption, to protect user data.
The app’s design phase follows. Here, the UPI application functionalities are outlined and visualized simplistically to indicate how each interacts with one another.
Some of the valuable functionalities that are a requirement for the typical UPI app include:
This process is necessary to allow users to register and utilize the app. Here, the developers involved should simplify the account creation process and offer precise information to improve the overall user experience.
The app’s development needs to have an intuitive user interface appropriate for users with diverse degrees of digital literacy. Prioritizing accessibility elements like straightforward navigation and simple design is essential. Doing so ensures that the app is inclusive and user-friendly for many audiences.
A swift transaction processing will help reduce waiting times for users. It is essential because users are fond of speedy modern technologies. Implement improved algorithms and backend infrastructure to ensure faster fund transfers and payments, increasing user satisfaction with the app’s performance.
The UPI payment app is built on a solid technical base to ensure a quick transaction. At the system’s core are high-performance servers that execute transactions quickly and efficiently. Load balancing techniques distribute incoming requests among several servers, reducing overload on a single server and ensuring continuous performance during high demand.
Scalable technology, the application’s database administration is speed-optimized to handle transaction data effectively. Using asynchronous processing, the app easily handles necessary non-real-time actions (such as notifications and confirmations). Technologies for real-time transaction monitoring are in place to keep tabs on the progress of every transaction. It aids in promptly identifying and resolving any issues and provides a seamless and accommodating user experience.
Furthermore, the technical design should emphasize secure API interfaces with banks, other financial institutions, and UPI platforms. These interfaces are optimized for speed and reliability, allowing seamless communication between the application and outside services. A robust network architecture for trustworthy and efficient data transfer ensures high bandwidth and low latency.
In the design, the UPI app must employ error-handling techniques to improve overall reliability and lower transaction failure rates. To provide a seamless and frustration-free experience, proactive notifications and instructive error messages must be provided to users to help them through any problems.
While the financing of UPI-integrated app development may vary, there are typical app development costs that need to be considered. However, the average cost range for developing a UPI payment App sits between the margins of $20k and $60k. These costs are summed up as a result of the following specific costs involved during the development process:
Development Team Costs :Â In developing the UPI app, it is a no-brainer to set aside money for project managers, UI/UX designers, developers, and quality assurance specialists.
Infrastructure Technology Costs : Funds for servers, cloud services, and other infrastructure may arise. Consider requirements for scalability, future growth, and maintenance costs. Check to see if the technological stack you selected meets the app’s needs for integration and maintenance.
Financial resources should be set aside to install vital security elements, such as encryption, safe API connections, and adherence to industry norms. To safeguard user data and uphold regulatory compliance, regularly invest in security assessments and updates.
Testing and Quality Assurance : These development phases are important stages in the app’s design, and money should be set aside for them. Testing should include user acceptability, integration, and unit tests. It is essential to consider the price of testing equipment, employ QA specialists, and resolve any problems found during the testing stage.
Funds should also be set aside for marketing plans to help publicize the app’s release. Take advertising, promotional, and digital marketing expenses into account. It accounts for the cost of press releases, app store listings, launch materials, and events.
Developing a UPI payment app requires combining technical skills and careful planning. The process of developing the app must involve a clear start, a thorough examination of requirements, and a design phase that gives equal weight to security and functionality. When the app moves into development, a solid technical foundation takes the lead in helping to develop an app tuned for dependable and quick transactions.
