With the dawn of mobile apps, all the banking and financial institutions have undergone phenomenal transformation towards advancing and upgrading technologies to meet customer’s expectations.

During its initial phase of expansion, mobile applications were not only taking the world by storm but also came towards the periphery of the banking sector and conquered it with a boom!

Before venturing more on the topic, first, try to answer some questions related to mobile apps. Let’s venture deep into this exciting journey!

What are Mobile Banking Apps?

First, banking as a sector is evolving with each passage of time and has revolutionized the way people look towards it by providing its services to run successfully on a mobile phone (or smartphone). Does that make any sense?

Yes, because it has disrupted the way of conducting financial services and has enhanced the reliability of the banks among the people. But what is mobile banking?

It is a service offered by banking and other financial institutions to permit customers to perform financial transactions remotely using their mobile devices. Unlike Internet banking, it uses software called an app which is provided by the respective financial institution to fulfill online banking purposes.

Hey, wait! You might be puzzled that online banking and mobile banking are different. How are they unique from each other? Let’s find out!

Differences Between Online Banking and Mobile Banking Apps

Even though online banking services have proved their caliber and have made financial transactions highly convenient for people, it is mobile banking that is in demand among digital users. Do you know why?

It is because digital users are smarter than you think and are ready to try new products that suit their persona. Besides the constantly evolving digital world, they are willing to adopt those trends that make banking simpler.

The same has happened with the onset of mobile banking which has made the banking procedure extremely convenient just at the fingertip of digital users and thus has become part and parcel of their life.

Some key differences between online and mobile banking are illustrated below:

I. Definition

Internet banking is a service that permits the conduction of financial transactions by customers using the Internet. Mobile banking is an internet-based facility provided by the bank to customers for executing bank transactions via mobile devices.

II. Functionality of Online & Mobile Banking

The functionality is the key difference between online and mobile banking services. Online banking is done through a PC (or laptop) with an internet connection mandatory. Alternatively, mobile banking can be done with or without the internet and even through SMS.

III. Accessing the Online Banking Portal & Mobile Banking App

Online banking portal is accessed from any browser without downloading the software, whereas mobile banking can be accessed only by downloading the appropriate banking app.

IV. Transaction Facilities

More banking facilities are provided through the online portal of the bank which simplifies internet banking. On the other hand, limited facilities are offered from mobile banking to the customers.

V. Opening of Online Banking & Mobile Banking Account

Your banking credentials are needed for opening an online banking account, but in the case of mobile banking, you must apply for it separately. Besides, various banks allow applying mobile banking through online portals.

VI. Funds Transfer

Fund banking in online banking is conducted using NEFT, RTGS, and IMPS and mobile banking is done through NEFT or RTGS.

These are some of the key differences that separate mobile banking from that of internet banking. Now, the importance of mobile banking for a bank will be discussed in the next step.

Why Mobile Application is Gaining Importance in the Banking Sector?

Before answering the given question, first, go through some important facts collected by Statista:

  • 30% decrease in the use of physical banks since 2017

Factors to Consider Before Choosing Technologies for Mobile Banking Apps

It is an uphill task to develop mobile apps for banking and other FinTech sectors because various technologies are taken into consideration. It is because the given sector requires that the banking app must be both competitive and functional so that customers get highly secure, authenticated, and UI/UX-based apps to ease their financial transactions.

However, there are a few fundamental principles that you should keep in mind when developing a mobile banking app without confusing yourself to make your project an utter failure.

I. Project Type for your app

A vital determinant in choosing the perfect technology for mobile banking app development. For example, if you are creating an app with platform-specific and great performance; then using technology such as Swift language will be beneficial for you.

II. Security from a Customer Perspective

Security is a multi-dimensional issue that you can ignore at your own peril. Once developed, apps must be properly secured from any breach that might affect their efficiency. So, thinking from the customer’s perspective; choose those technologies that can minimize the human element in security control.

III. Apps must be Future-Proof

Just making your app more secure is not enough to meet your customers’ expectations. You must use technologies that come with updated features and focus on recent marketing trends to make your banking app more user-friendly and acceptable among people.

Today is a time with stiff competition and if you choose a technology that has an ample number of ready-made solutions, then it will be crucial for you to have a great competitive advantage against your rivals.

VI. Apps must be Differentiable to Stay Away from Competitors

If you are one step ahead of your competitors; then no one can stop your app from having wide appeal among your audience. To get a competitive edge, select a technology that should include an outstanding feature in your mobile banking services and stand out among the crowds successfully.

VII. Personalized App is a Stepping-Stone to Success in the Banking Sector

Surely, having an extra feature in the banking app will give you a competitive edge, but offering a high user experience will make your app more successful. Choose that technology that collects relevant customers’ information and helps in meeting their expectations wisely.
