  7. Ensure Legal Compliance Before Developing a Fintech Application

  8. While developing mobile banking apps, it is essential to apply security protocols to save your FinTech app from illicit activities. To prevent such activities from happening, it is essential to follow legal compliance. Since it is a FinTech app, users will send mobile payments to others, involving important data that must be kept secure.

    If security precaution is not taken, there is a chance for the hackers to steal users’ personal information. We have mentioned points related to legal compliance you should consider before you create a FinTech app and finalize it.

    • Comprehend the legal agreements related to users’ financial data using APIs
    • Generate data privacy and management policy
    • Offer insurance policy to cover any accidental breach
    • Create a backup in case of disaster recovery and business continuity

    You need to hire a leading mobile app development company like Space-O having experienced app development team that will help you to build fully functional FinTech mobile app. Additionally, we follow all the compliances to ensure your idea remains confidential and crucial business information safe.

    Taking Care of Jurisdiction While Publishing Apps in Different Countries

    The confidentiality agreement protects your idea from getting exposed. Therefore, it is advisable to sign an NDA to protect your idea before sharing your FinTech application idea with any mobile app development company.

    Prevent Your Product by Having Intellectual Property Rights

    All work that is original and developed during the mobile app development process is referred to as intellectual property (IP). You and your team will create legal app concepts, original content, designs, logos, app names, source code, and more during the app development process. It is suggested to register trademarks, copyright, or patents to get protected against your app idea.

    Protect Your Contracts With Additional Data Usage Clauses

    Contract signing is an advantageous process for both parties. The contract contains the responsibilities of both parties, the discussed technologies, cost, the flow of work, and timeline as well. Always include the clause of confidentiality, code ownership, and terms of use of open-source software.

    Privacy Policy Update

    The privacy rights of app end-users should not be disregarded. A privacy policy is the most common technique to address the privacy rights of mobile app users.

    End-user License Agreement

    End-user Licensing Agreements or EULA are required when the consumers download or install a mobile app. EULA is required since copyright laws protect the app. Also, EULA is an agreement between the app’s owner and the app’s users. In the below image, the license agreement and privacy policy are available for you to read.

    Check these screenshots for your reference. You must have these two pages on your Fintech application.

  11. FinTech Mobile App Development

  12. After deciding on the tech stack, the next step will be to design the front end of the FinTech app. The design plays a major role in terms of gaining users’ attention and increasing user engagement. The colors, style, and feel of the app are some of the crucial factors considered while developing the front-end of a mobile app. The next part will be to build and develop components that interact with users.

    The front-end app development focuses on delivering perfect user requirements with a positive user experience.

    For example, if you are building a FinTech app make sure to design a simple and intuitive app. Display numbers and charts in an engaging way. Don’t try to overcomplicate it for users. Make your app design responsive for users.

    There are numerous technologies on which to develop a back-end. The choice between Python, Java, and even Golang is usually chosen by the scale of the project, the requirement to deal with legacy infrastructure, and plain old performance.

    However, there are certain key considerations to make when selecting a back-end technology for your FinTech business.

    • Is it possible to easily scale FinTech solutions later by using these technologies?
    • Will these technologies help to develop a FinTech app with robust infrastructure?
    • Will the selected technologies deal effectively with regulatory issues quickly?
    • Is it possible for these technologies to resolve customer interface quickly?

    Even API development plays an important role while building FinTech App. This means that Financial institutions provide specific APIs for third-party access to their client services. After that, multiple 3rd parties use banking services or provide them to their customers.

    If you are planning to build a FinTech app, consider applying for the below-mentioned back-end technologies.
