Banking applications represent a wide financial industry of software development processes. Globally, apps are computer programs designed for specific purposes while banking apps focus on managing financial services/products.

So far as we live in the digital era, it’s impossible to imagine a bank without certain applications integrated. The most traditional companies use only accounting software like Excel but more modern brands focus on mobile banking app development: ERP systems for 360-degree control of business processes, CRM tools for smoother interactions with clients, online banking applications with personal profiles, and mobile wallets for on-the-go finance management.

In fact, nearly all leading banks use apps, especially mobile ones. According to the Retail Banker International’s 2018 ranking, there are dozens of famous names in the list of the best mobile finance solutions. You can find there the Bank of America, Barclays, BBVA, UBS, Wells Fargo etc. Well, here’s the question: does your bank have apps for employees and/or customers? And if the answer is no, it’s time to learn how to develop an online banking application, install it, and boost the company’s results with it. Let’s go!

The best examples of banking mobile app development

Basics of Online Banking App Development

Obviously, to evaluate development/implementation features and general benefits of finance app development, we have to understand what these apps stand for. In this section, you will discover definitions of mobile banking solutions and ones for web browsers, distinguish differences between products for your staff and customers, as well as reveal what MVC means and how it can help during banking application development.

Differences Between Online & Mobile Banking Apps

Let’s begin with mobile banking and so-called online banking differences. While these approaches are quite similar, they stand for different tech solutions for banking. Generally, the simplest definitions are:

  1. Mobile banking. Includes applications designed for smartphones and tablets through which customers can access their financial data and perform transactions.
  2. Online banking. Covers software and programs built for web systems and/or desktop. Usually, clients can enter their accounts through official websites.

Hence, the core difference is that mobile banking focuses on mobile devices while online one refers to desktop systems. Still, when you use a smartphone browser to enter the bank’s system, you technically use services of online banking. It takes more time and resources to design and develop a website to display the online banking system, so currently, a lot of financial institutions introduce lightweight minimalistic mobile solutions.

Another thing we should look at is a model-view-controller approach or, simpler, MVC. According to Wikipedia, it’s an architectural pattern which features three linked elements and serves for designing user interfaces. In accordance with the name exactly, the parts are:

  • Model. The data structure which handles info, logic, and rules.
  • View. The final visual output, the result which user wants to get from the system.
  • Controller. The agent which translates orders into commands for the model.

All parts are independent of each other.

Types of Mobile Banking Apps

Concluding our journey to the roots, we also want to look at different banking software types. The following categories stand apart from the previously mentioned mobile/web classification because they can relate to both of these entities. Long story short, there are two apps’ types with completely different purposes:

  1. Employee-oriented. Specific tools and systems for managing the internal business processes like controlling finances or analyzing clients’ data. In this case, financial mobile application development is not necessary but desirable because real-time connections between the bank’s branches and departments boost performance greatly.
  2. User-oriented. On the other hand, there are applications for customers such as online desktop interfaces, mobile wallets, virtual cards etc. They facilitate interactions greatly as clients can save time on visiting banks or calling them. For banking mobile banking app development, online feature is obligatory.

As well, you can find solutions which combine these parts. For instance, ERP products often include both managerial tools for in-house tasks (accounting, employee training, tracking cash flows) and functions for interaction with clients (mostly, CRM apps and personal profiles of users).

Security Issues of Mobile Banking Apps

One of the biggest threats related to financial mobile application development is focused on security. Surprisingly, even big American banks fail to set high security standards in their native applications. Studies conducted by Zimperium show that analyzed apps were based on outdated coding practices, old open-source libraries, unencrypted HTTP connections, etc. 

Precisely, the most popular security issues  are as follows:

  • Fraud. Cyber criminals can access databases with screenshots and other remote-deposit stuff. Thus, they can copy images and get users’ credentials. 
  • ID vulnerabilities. Even fingerprints and face recognition practices can’t protect the app fully. Needless to say that hackers know how to breach traditional systems. 
  • Malware. Viruses evolve constantly adapting to new protective measures. Thus, it’s better to always keep your mobile updated and protected. 
  • Poor design. Usage of old code and libraries lead to more vulnerabilities. Also, remember about third-party connections that can be designed poorly. 
  • Unsecure connections. This point includes both mobile and wireless links. Just never access your bank via public Wi-Fi, it’s a golden rule. 

Key Insights into Mobile Banking Application Development

Now, it’s time to look closer at features and stages of creating banking software. We will start with mobile solutions and later will check desktop/web platforms, too.

To start with, check some shiny stats. As Juniper Research claims in its 2018 report, users of iOS and Android banking apps will grow 14% YOY while traditional online banking clients will have only 6%. Currently, half of the digital banking users access their financial institutions via mobile applications while a lot of top-rated banks are ready for great digital transformations (see details in the chart below).

4 Best Practices for the Mobile Banking Apps Development

Here, meet the most important section of the guide as it covers the entire path of developing and integrating a mobile solution for your bank. Surely, we will look at the development from the entrepreneur’s point of view because tech details are dispensable. You can leave tech stuff to experienced teams like our company to avoid pitfalls and problems. We handle the process and deliver quality actual content without hidden hourly costs.

Pay attention to the idea of best practices. Simply put, it’s a set of methods or approaches which are widely accepted as the most efficient for the given purpose. The best practice (or way, if you want) of creating Android banking apps is right below. Thus, let’s focus on core things related to mobile banking app development!

1. Understand Your Customers

First and foremost, you should start by analyzing the audience. Numerous people of all ages and races utilize banking services and now they tend to use mobile applications or online platforms instead of visiting branches or calling contact centers. The usage of these software types grows rapidly. The PwC’s survey conducted in 2018 marks that 15% of all customers used mobile devices to interact with banks. Compare this number to 10% in 2017. While old channels like ATMs and branches move down, mobile banking is on the rise. 

Considering such growth, it’s important to understand what your clients want and why they look at banking mobile app development. Valuable data from Statista reveals the benefits and expectations of the US-based users in 2017 and 2018. That, top reasons of using mobile apps include verifying balance (77%), verifying transactions (63%), transferring money (53%), and making deposits (51%) while the definitive benefit is an awareness of the current personal financial situation (62%). Check more detailed stats below.

2. Focus on Security

The next thing you should check is the most important feature of all financial applications and platforms. So far as the company works with money (often, big money), it has to provide perfect guarantees of safety. Customers will appreciate apps with proper security measures. Following the idea of mobile banking app development best practice, here are some notable points you should remember:

  • Check security policies. If you already have certain apps, make sure they work fine and are compatible with planning new products in terms of security.
  • Configure servers. Test platforms to know that they are protected from phishers and spam apps. Especially, you are interested in mobile protection.
  • Integrate 2FA. Simply put, add an option of second login confirmation via SMS or Google Authenticator. 2FA is a necessary feature for modern systems.
  • Add digital signatures. They are similar to real ones but are designed for online use. Let your clients verify transactions with unique signatures for better security.
  • Insert password checkers. It’s another common function which notifies people about their passwords’ reliability. Ideally, passes should include various characters.
  • Make inactive sessions expire. Frauds often get access to open accounts. Close such sessions automatically after a few minutes of inactivity.
  • Avoid jailbroken mobile phones. Jailbreak opens the entire system of a device but reduces security greatly. Prevent installing banking apps on such gadgets.

Finally, you should always notify clients about needful security measures by issuing news and manuals. Tell people that using a native app is much safer than accessing online banks via browsers, inform users via online chats and SMS, educate them about the importance of strong passwords, transactional limits, apps’ updates etc. Be sure that your audience is tech-savvy.

3. Be Simple and Ergonomic

On a par with security issues, users are afraid of high complexity of applications. Usually, people want only a few basic functions accessible on-the-go via smartphones instead of fully-functional large apps which consume traffic greatly. Thus, clients focus on three key purposes: check the balance, transfer money, and contact the bank’s support center. During banking application development, focus on them, primary.

According to the study conducted by Keynote Systems in 2013, the functionality affects loading times greatly. For example, Charles Schwab’s application has led the ranking with 5 seconds average response time and the product from the Bank of America was the slowest one with about 30 seconds. Reasons are clear as the first app has featured 6 elements while the second was packed with 58 ones! Compare these times with the 7-second attention span of modern users to understand why simplicity is crucial.

Apart from core functions and lightweight applications, you should focus on several major points when it comes to design:

  • Utilize corporate styles. Create minimalistic and ergonomic apps in traditional company’s colors and with recognizable logos.
  • Add personalization. Arrange page elements in accordance with the user’s needs and daily operations. For this, you should analyze big data about each client.
  • Interact with customers. Alert them about updates, send push notifications about transactions, and engage them with the news.
  • Avoid overloads. To do this, you can launch several mobile applications for different purposes. Always connect them to the basic website.

4. Remember About Different Devices

As the audience utilizes different smartphones and tablets from dozens of manufacturers with various operating systems like Android, iOS, and Windows Phone, you will have to remember about all variations. Gadgets feature different screens, features, and cache sizes. Some users don’t want to update OS versions regularly, so you also should support older products. At all, this takes us to two key ideas.

  1. Run as many tests as you can on different devices including real and emulated ones. Proper pre-launch testing can save you from numerous bugs and further user complaints.
  2. Integrate analytic systems to gather metrics and evaluate performance. With it, you will be able to spot and solve problems quickly, collect user experience, and upgrade applications.

We start with business analysis to know more about your clients, then develop cross-platform solutions for various devices, and support the released product 24/7. We also can add powerful tools for in-house analysts or outsource this task and send you already processed data with tips on attracting and retaining customers.

Key Points of Banking App Platform Development

As we already know about mobile applications, it’s time to check platforms for web browsers and desktops briefly. Long story short, this software is more complex as it should include all necessary features, not only the three mentioned above. Through online platforms, users can interact with banks while employees use managerial and analytical tools.

While mobile solutions for banking are usually designed for customers exclusively, advanced web/desktop platforms divide into two large groups. Of course, your staff can access all-in-one ERP through mobile phones but these mobile apps come as a part of bigger platform-like systems. Thus, let’s check how they differ.

Systems for Internal Purposes

Using finance app development approaches, you can create a powerful solution for staff. The best example is ERP software because it connects in-house departments and collects data from them using single storage. Banks benefit from ERP because the system provides for smooth cooperation between branches located in different regions and even countries. Using such applications, your team can pass on daily tasks to automated helpers (particularly, ones with the integrated AI features), exchange essential data quickly, and eliminate human errors in accounting and finance sectors.

In our company, we deliver all types of internal solutions including investment banking app development, 360-degree ERP for international corporations, and minimalistic products for small local banks. Tailor-made apps are wonderful because you get exactly what you need without hidden costs or unnecessary functions. We are fully responsible for results because prefer to work as partners rather than outsourcers.

User-Oriented Products

Similarly, you can create a website or desktop client for customers. Such user interfaces should represent all core features such as checking balances, making transfers, reviewing history, interacting with support services, and so on. Basically, platforms are advanced versions of mobile apps and they are suitable for expanding user experience with extra functions.

CRM systems are also among the described products. On the one hand, they are designed for internal use because they collect clients’ data and simplify interactions between customers and banks’ operators. On the other hand, CRM software is focused on end users and serves for boosting their experience with personalized approaches.

It’s not an easy task to design and develop a website to display the online banking system. But we offer these applications, too. Our UI/UX department guarantees that your platform will come with great usability and smooth design. Surely, further support of the developed website is provided.

What Are the Key Features of Mobile Banking Apps?

Considering differences between mobile and web/desktop products, let’s look at the major functions of these software types. The next two sections reveal features of core (web/desktop) systems and mobile solutions.

Features of investment banking app development

Core Banking Services

Core banking functions as a back-end system which processes users’ orders and makes it possible to complete requests. Today, core banking software is inextricably linked with front-end interfaces for clients. Generally, there are a few primary core features:

  • Account management.
  • Deposits and withdrawals.
  • Transactions.
  • Loans and interests.
  • Payment processing.
  • Personalized offers.
  • Loyalty programs.
  • Customer support.

When it comes to internal core processes, you should be interested in a-class applications for clerks. They cover forecasting of the clients’ needs, scheduling tasks and appointments, advanced security measures etc.

Mobile Banking Services

As we have stated earlier, mobile applications must be simple but functional. As users don’t look for all core features integrated into their smartphones, it’s enough to focus on the most essential ones such as:

  • 24/7/365 access to accounts.
  • Money transfers.
  • Bill/loan payments.
  • Notifications.
  • Customer support.

If you want more cutting-edge things, try to use unique devices’ elements, e.g. integrate camera support for remote deposit capture feature or link GPS so users will be able to find the nearest branch or ATM. Consider also voice/gesture navigation, biometric authorization, QR tech for withdrawals, and cashback services. But don’t overload your mobile app, keep it fast and plain.

The financial industry is a highly-dynamic environment. Today, when many new startups tend to disrupt the ecosystem, banks should adapt by introducing new technologies, interaction options, and features. That’s why 2019 and 2020 will be years of great changes. If you know the emerging trends, it will be easier to survive. 

Here are five of the most prominent trends in the finance mobile app development for 2020:

  1. Blockchain. Decentralized systems are here to stay. They introduce innovative forms of financial management, particularly for mobile phones. High privacy and transparency combined with coverage can help a lot of underbanked people. 
  2. Cardless ATMs. Modern banks slowly move away from plastic cards and focus on mobile-only processes. Thus, we can expect for NFC-based ATMs that will allow customers to deposit and withdraw funds using smartphones only. 
  3. Open banking.  According to the recent EU directives, banks should open their platforms for external producers. This cooperation will help FinTech startups to deliver better services using banks’ infrastructures. And users will get more cool apps.
  4. Smart bots. Thanks to AI and machine learning, conversational machines become smarter and smarter. Todady, they help users to check balances, transfer money, and so on. Tomorrow, they will replace human operators, most likely. 
  5. Voice banking. Combined with bots and other AI systems, voice commands will make our life way more convenient. Phones will act as mobile hubs through which users can do almost anything from the bank-related tasks.
