What is a Mobile-Only Digital Bank?<\/h2>\n\n\n\n

No need for elaborate explanations \u2014 the name speaks for itself. Mobile-only banking is banking for which a user requires only a smartphone with the installed app. All operations, transactions, monitoring, and other user interactions are performed via the app. Basically, a mobile-only digital bank is a bank at your fingertips. Banking cards are still present, though, so users can withdraw cash using ATMs. <\/p>\n\n\n\n

Mobile-only banking apps strive to emulate real banking experiences but make the latter as convenient and fast as possible. However, different apps may introduce different features and pleasant bonuses that set them apart from the competition. Digital banks come in great variety, and there is pretty much no one-size-fits-all mobile-only bank solution that will satisfy all users. The variety of options means that customers can choose a digital bank they think is the best for them. It also means that there is always free space for digital bank contenders who aren\u2019t afraid to try something new. <\/p>\n\n\n\n

Here are the things you need to consider before starting your mobile-only bank.<\/p>\n\n\n\n<\/a>\n\n\n\n

Pros and Cons of Mobile-Only Banks<\/h2>\n\n\n\n

So, mobile banks are great and convenient, but to what extent exactly? What are the advantages and disadvantages of using digital banks? <\/p>\n\n\n\n

Pros of Mobile-Only Banking Apps<\/strong><\/h3>\n\n\n\n

Omitting the obvious benefits of convenience, 24\/7 access, and minimization of bureaucracy, mobile-only banks have the following pros:<\/p>\n\n\n\n

    \n
  1. Easy to set up and start using<\/li>\n<\/ol>\n\n\n\n

    It\u2019s criminally easy to become a user of a digital bank and start indulging in its convenience in comparison to traditional banking. For example, with most digital banks, it is as easy as downloading the app, registering, verifying your identity, connecting a money account, and starting using the app even before you\u2019ve ordered a physical card. Ordering a physical card is also easy as one-two-three, after which it will arrive to you as soon as possible.<\/p>\n\n\n\n

      \n
    1. Fewer and lower fees<\/li>\n<\/ol>\n\n\n\n

      Digital banking does not have to deal with the humongous bureaucratic machinery, which means lower overhead costs. The latter allows digital banks to implement fewer and lower fees because they don\u2019t need as many income sources.<\/p>\n\n\n\n

        \n
      1. Smooth user experience<\/li>\n<\/ol>\n\n\n\n

        Mobile banking is extremely user-centric. The apps are created to make a customer feel like a king of their own little financial kingdom with 24\/7 customer support, a variety of banking operations that are a few finger taps away, intuitive user flows, impeccable user interface, and appealing design. If a good digital bank can\u2019t make a user feel happy and special, then pretty much any financial service provider can\u2019t as well.<\/p>\n\n\n\n

        And the Cons of the Mobile-Only Banks Are<\/strong><\/h3>\n\n\n\n
          \n
        1. Security concerns<\/li>\n<\/ol>\n\n\n\n

          The overall convenience and immediacy of digital banking have its downside \u2014 security. As far as all operations are performed via the Internet, a high-quality online banking app should have bulletproof and foolproof security, so a user can trust the app every time he or she presses a button \u2018send\u2018 or \u2018submit.\u2019 Nonetheless, the silent voice at the back of a user\u2019s head that reminds them about the vulnerability of the personal data and money may never go away. However, as the software evolves and people change their views, this issue slowly diminishes.<\/p>\n\n\n\n

            \n
          1. No Digital Bank ATMs<\/li>\n<\/ol>\n\n\n\n

            Mobile-only banks don\u2019t have their ATMs and have to rely on partnerships with other banks. However, the latter is not always there. Therefore, sometimes the only choice is to withdraw cash using an ATM that charges significant fees.<\/p>\n\n\n\n

              \n
            1. No human-to-human interaction<\/li>\n<\/ol>\n\n\n\n

              The absence of the possibility to come to a bank and talk to a real consultant or a teller may result in the lack of flexibility regarding services and transactions. And, hey, live interaction with another human being may be a pleasant experience, even if it\u2019s a completely formal event. Especially now, in the era of social media.<\/p>\n\n\n\n<\/a>\n\n\n\n

              Features of Mobile-Only Banks<\/h2>\n\n\n\n

              A well-rounded mobile bank should have the following core functionality:<\/p>\n\n\n\n

On top of that, the mobile-only bank may provide small loans, set overdraft limits.<\/p>\n\n\n\n

              Secure interaction<\/h3>\n\n\n\n

              Multi-factor authentication, end-to-end encryption, secure back-end architecture, foolproof UX, and best coding practices that help to avoid weaknesses in the software\u2019s construction should make the mobile-only banking app a digital fortress. Security should be the first concern while developing an app, and the last concern, basically an alpha and omega of mobile-only banking app development.<\/p>\n\n\n\n

              Engaging User experience<\/h3>\n\n\n\n

              Unlike traditional banks, their mobile counterparts should be fun to interact with. Customizable user experience, timely notifications, gamification with achievements, and flawless UX will help you to achieve this goal.<\/p>\n\n\n\n

              24\/7 Customer Support<\/h3>\n\n\n\n

              Insert testing activities as early in the pipeline as possible and make sure the application is secure and fast before releasing it to a broad public. <\/p>\n\n\n\n

              Step #8: Update<\/strong><\/h3>\n\n\n\n

              Collect feedback and integrate helpful insights into new features and releases to cater to your audience\u2019s needs and wishes.<\/p>\n\n\n\n<\/a>\n\n\n\n
