Fintech App Features

Some important fintech app features that you need to know:

  • Multi-user Collaboration

To complete a financial transaction, you need an intervention by more than one party. You can understand the scenario with example, one person can transfer funds to another or a bank lends money to its customer. 

To enable multiple users to use the app, it is important to have a multi-user collaboration. They can complete deals, tasks, and transactions through one app only instead of using two different apps. 

For example:

KhataBook is a digital ledger app that enables small businesses, shop owners, and merchants to manage their financial transactions, credits, and debts collaboratively. It simplifies the process of tracking accounts, expenses, and payments between businesses and their customers.

The app allows multiple users, including business owners and customers, to collaborate on financial transactions. Businesses can share transaction updates with their customers and vice versa, facilitating transparency and reducing the complexities of manual bookkeeping.

KhataBook’s multi-user collaboration features empower small businesses and merchants to maintain accurate financial records, strengthen customer relationships, and improve transparency in financial dealings.

The app addresses the challenges of manual bookkeeping, reduces misunderstandings between businesses and customers, and aids in maintaining clear financial histories.

  • Biometric Authentication

Biometric authentication is about using a person’s unique characteristics like facial features, fingerprints, or voice for recognition. Users can deploy biometric authentication in place of password or login access.

It enhances security because creating a duplicate biometric component is not easy. 

Finances involve worries. In one example, Paytm is one fintech brand that offers a wide range of financial services. Paytm incorporates biometric authentication methods, such as fingerprint and facial recognition, to enhance security and streamline user access to their accounts.

By enabling biometric authentication, Paytm enhances user security, reduces reliance on traditional passwords, and provides a seamless and secure experience for financial transactions.

Biometric authentication has become an integral part of Paytm’s user experience, offering a quick, convenient, and secure way for users to access their accounts and carry out financial activities.

  • Chatbot Support

Chatbot Support enables fintech apps to keep in touch with the customers and resolve their queries fast when need be. 

Customers can also approach the financial apps for any glitches. 

Kotak 811 is a digital banking platform by Kotak Mahindra Bank that offers a range of banking services through a mobile app, including account opening, payments, fund transfers, and more.

Kotak 811 app integrates a chatbot feature known as “Keya.” Keya serves as a virtual assistant that provides customers with real-time assistance, answers queries and performs various banking tasks.

Keya chatbot enhances customer engagement, offers instant support, and provides a self-service option for everyday banking tasks. The convenient user experience, enabling users to interact with the bank’s services through natural language conversations.

  • Cross Platform Integration

Cross platform integration allows users to connect with other apps or platforms for better functionality. The integration makes life easy for users.

PhonePe is known for its seamless cross-platform integration, allowing users to access and use its services across various platforms and applications.

PhonePe’s cross-platform integration provides users with a unified experience, enabling them to conduct financial transactions seamlessly across various services.

The ability to use PhonePe’s services across different apps and platforms has contributed to its widespread adoption and popularity as a digital payment solution in India.

  • AI for Analytics 

AI enabled fintech apps give access to data analysis and market visualisation. The apps can generate charts, graphs, and other data visualisation tools enabling users to identify their financial health. 

Zerodha is one of India’s largest stock brokerage platforms, offering trading and investment services in stocks, commodities, derivatives, and more.

These AI-powered analytics tools give users insights and data-driven trading and investment decision recommendations.

By integrating AI-driven analytics, Zerodha empowers traders and investors with data-driven insights that can aid in making informed decisions and managing risks. The app allows users to harness the power of technology to enhance their investment strategies.

Challenges faced in Fintech App Development

Fintech app development comes with its challenges due to the complex nature of financial services and the need for stringent security measures. Here are some detailed challenges faced in fintech app development:

    • Ensuring the app remains responsive and efficient under high loads is a constant challenge.
  • Data Accuracy and Integrity:
    • Fintech apps must ensure data accuracy, especially for financial calculations, to avoid errors impacting users’ finances.
  • User Experience (UX):
    • Providing a seamless and user-friendly experience is crucial in fintech. Complicated user flows or unclear instructions can lead to frustration and abandonment.
  • Emerging Technologies:
    • Staying up-to-date with evolving technologies like blockchain, AI, and biometrics is essential for staying competitive in fintech.
