Feature To Add In Fintech Application

There are some must-have features in all Fintech applications. Here are seven of them for you to consider for Fintech Application development

1. Sign Up And Sign In

A smoother user journey requires an effective onboarding process, which should be evident right from the signup process. Design the signup process to quickly onboard users.

Offering a social media login process can set your app apart. Users should be able to choose among different authentication methods for logins. Using such secure signup and sign-in will help establish trust among users right from the onboarding stage.

2. Dashboard

The dashboard gives users a comprehensive overview of their financial information and activities. Users can leverage the dashboard to manage financial investments, daily transactions, and loans. Designing a personalized dashboard with relevant graphs and charts offers users clearer data displays.

It can display account balances, transactions, and other details of a user’s linked bank accounts in one place. It allows users to set budgets, categorize expenses, and track spending patterns, investment portfolio breakdowns, and performance analysis.

Users can regularly track their economic progress with all these insights into their financial activities in a dashboard.

3. Payment Gateway

Integration of Payment Gateways is necessary for secure transaction processing. These gateways act as mediators between users and merchants, facilitating secure transactions for financial apps.

Multiple payment gateways and payment methods will increase user adoption, improve access, and reduce transaction failures.

Multiple payment gateways ensure widespread use and availability. This is because many regions support specific currencies and payment methods.

4. QR-Code Payment

QR-code payments in fintech allow users to make mobile payments conveniently from anywhere and anytime. Users can instantly make payments by scanning QR codes displayed by merchants. They can even generate unique QR codes to receive payments from others into their bank account.

Open a bank account and set a PIN code to transfer payments securely. You can also charge merchants monthly for having their own QR code to accept payments.

QR codes are becoming a more common means of payment. By 2025, the number of QR-code users in the USA will reach 99.7 million. This indicates how adding QR codes to your Fintech app can help attract more customers.

5. Security

Data safety is crucial in a Fintech App because users entrust the platform with their personal
financial information. Some of the security features that you can add are,

Fingerprint scanning: It scans the unique pattern of your fingertip. Fingerprint scanning requires a touch to monitor, and it is hard to fabricate the fingerprint.

Facial Recognition: analyzes traits like eye distance and nasal structure to authenticate logins based on user-specific features.

Two-factor Authentication: requires users to verify their identity. Using both a password and a code sent to their registered phone or email.

Voice Authentication: analyzes the user’s voice pitch, accent, and speaking habits to create a voiceprint for authentication. Users need to talk into a microphone to authenticate their access to the app.

With the integration of all these security features, unauthorized access to the platform is virtually impossible.

6. Chatbots

AI-powered chatbots are becoming a common feature in apps across all industries. They reduce the customer service workload by providing instant assistance with queries or grievances, thereby cutting response times.

Customers can quickly ask questions about various topics, including financial management, account tracking, account balance, add-on services, etc. If a complex issue requires more attention, chatbots can forward it to a dedicated customer service executive for handling.

7. Push Notifications

Instant Notifications and alerts features can keep them informed and engaged with the app. This feature notifies users on their devices about transactions, account updates, low balances, upcoming bill payments, and promotional offers.

These real-time notifications keep users informed about their transaction status. Help them manage budgets effectively, track portfolio updates, avoid late fees or penalties, and make informed financial decisions.

4 Challenges To Build A Fintech Mobile App

From skilled developers to maintaining data security, a business can face many challenges while developing a Fintech app.

1. Finding Skilled developers

With the Fintech industry’s growth, the demand for Fintech app developers has been increasing.
Finding developers with experience in building a Fintech app is challenging. Developing a Fintech app requires knowledge and understanding of the different aspects of its development.

For example, a Fintech developer needs to have skills in,

  • Programming Languages,
  • Cloud Computing,
  • Database Management,
  • Regulatory Knowledge,
  • Data Analytics,
  • Cyber Security
  • Quality Assurance, and
  • Communication

Skills are not the only factor that matters, and cost also matters. You can outsource software developers instead of having an in-house team, reducing overhead costs. Plus, you won’t have to worry about training them.

2. Picking the suitable Tech Stack

Choosing the right tech stack is crucial to building a secure and scalable Fintech application. It forms the basis of creating. For instance, you can select fast and reliable programming languages.

It should also be compatible with major cloud platforms like AWS, Azure, and Google Cloud. So, adapting to the new scale is easier if your business grows. The app will need to manage large volumes of data and user traffic.

Here, Database Management solutions such as MySQL or MongoDB can assist Fintech apps in effortlessly handling millions of transactions. Similarly, there are many other aspects of the Fintech technology stack that you need to consider.

3. Data Security and compliance

The Fintech industry is one of the domains most targeted by cyber attackers. In March 2024, the American Express data breach exposed customer personal information, including names, account numbers, and card details. Due to unauthorized access through a third-party merchant processor.

Amex reported OCABR for 16 data breaches between January 19 and March 7, 2024. This shows why Implementing a robust security infrastructure is so crucial.

These hackers can perform several attacks that you must consider when designing security measures. One of them is a DDoS (distributed denial of service) attack. It attempts to bring down an application by overloading it with traffic.

To prevent such attacks, you must consider features like rate restriction, KYC, biometric authentication, and two-factor authentication. You must also follow the FTC Safeguards Rule and the CFPB Fair Credit Reporting Act.

If your app involves investment and trading, you’ll need permission from the Financial Industry Regulatory Authority (FINRA).

4. Designing the right UX

The biggest challenge for Fintech firms is creating an app that simplifies financial terms and processes. Therefore, the focus must be on creating a user-centric interface that offers a frictionless user experience.

Implementing extra steps like a confirmation prompt or alert box can help users avoid making easy mistakes. Further, balancing appealing designs, features, and a smooth workflow is essential.

A Fintech app needs a simplified UI with highly responsive elements. This will allow users to navigate through the app and access features easily.
