The key advantage of mobile banking lies in its flexibility, enabling users to engage in banking activities anytime and anywhere. However, drawbacks include security concerns and a comparatively restricted set of features when compared to in-person banking or using a computer.

A Brief History Of Mobile Banking

Before the advent and widespread adoption of mobile web services in 1999, mobile banking primarily relied on text or SMS, known as SMS banking. European banks were pioneers in offering mobile banking services, using the mobile web through WAP support.
SMS banking and mobile web were the dominant mobile banking methods until around 2010. The emergence of smartphones with iOS or Android operating systems led to the evolution of mobile banking applications (apps). Clients could now download banking apps onto their smartphones, offering more sophisticated interfaces and enhanced transactional capabilities.
Presently, numerous financial institutions leverage both SMS and mobile applications to keep clients informed about account activities, send alerts about potential fraud, and communicate updates and maintenance schedules. For instance, a bank might text users to let them know that ATMs or apps will be temporarily unavailable due to system maintenance or to confirm a transfer that a client started using the mobile app.

Types Of Mobile Banking Services

Mobile banking services can be classified into the following categories:

Account Information Access

Clients can access their account information, including balances, statements (through mini-account statements), transaction history, term deposits, loan or card statements, and, in some cases, insurance policies.


Transactional services facilitate fund transfers within the same institution or to other institutions, self-account transfers, payments to third parties (such as bill payments), and collaborative purchases with other applications or prepaid service providers.


Investment management services allow clients to oversee their portfolios and obtain a real-time view of their investments, including term deposits.

Support Services

Support services enable clients to check the status of requests for loan or credit facilities, follow up on card requests, and locate ATMs.

These apps simplify the process of sending money to friends and provide quick access to customer service representatives with just a tap.

Accessing The Bank 24/7

In contrast to a traditional bank branch, mobile banking offers convenient access to your account at any time, with only occasional exceptions like scheduled maintenance updates or unforeseen outages.
This accessibility not only saves time but also introduces practical features like mobile check deposits available in many banking apps. This allows users to deposit checks conveniently, whether on the move or from the comfort of their homes.
Additionally, mobile banking can serve as a reassuring alternative for individuals who may have encountered in-person discrimination, providing a more inclusive and accessible financial experience.

Making It Easier To Save

Top-notch mobile banking apps have transformed the way you handle your finances, making money management more effortless. Certain online banks are introducing inventive savings features within their apps.
For instance, Varo Bank, a well-known online bank, provides a "Save Your Pay" feature that automatically sets aside a predetermined percentage of your paycheck every time it is deposited. Mobile banking apps offer spending alerts as another means to enhance your financial optimization.

Paying IOUs

Using your mobile banking app, repaying someone you know is a seamless process. Many banks collaborate with Zelle nationwide, allowing you to send money to someone within minutes through the bank's mobile app, eliminating the need for cash or checks.
All you need is the recipient's email address or phone number to initiate the money transfer. In cases where your bank doesn't support Zelle, you can typically transfer funds to another person's bank account by providing their routing and account numbers.

Strengthening Security

Banks specialize in safeguarding your assets, including transactions conducted through their mobile apps. While no system is entirely foolproof, there are measures you can take to enhance security when it comes to mobile banking.
Typically, financial institutions mandate a username and password for accessing a mobile app and incorporate additional safety features to fortify your account. Multi-factor authentication, for instance, necessitates two forms of verification: initial input of account credentials (username and password), followed by a text containing a numeric code sent to your phone, which must be provided to gain access.
Moreover, certain mobile devices and bank apps offer the option to log in using facial recognition or fingerprint scanning, providing an additional layer of security without compromising convenience.

Tell You Where Your Financial Data Is Going

Numerous consumers share their bank data to utilize services such as Venmo and Mint. Managing multiple outside apps can be challenging when it comes to remembering which company possesses specific bank data. To simplify this process, several banks are making efforts to assist customers in comprehending and tracking the sharing of their data by altering the way information is exchanged behind the scenes.

Tracking Expenses

Effectively managing and adhering to a budget often involves the labor-intensive task of tracking all your expenses, which might even lead to abandoning budgeting altogether. However, mobile banking apps can significantly alleviate this burden by automatically monitoring and categorizing your expenses linked to a specific account.
These apps provide a comprehensive breakdown of total expenditures, such as utilities, dining, transportation, and more. By analyzing your spending patterns through these apps, you can obtain a clearer insight into your financial habits, enabling you to identify areas where adjustments may be necessary.

Mobile banking eliminates face-to-face interactions with bank tellers. While this may not pose a problem for many customers, it can be a drawback for those who prefer assistance or have complex financial inquiries requiring in-depth guidance. Some mobile banking apps may offer alternatives like live chat or phone contact with a banker directly from the app.

Types Of Mobile Banking Fraud Cases

Fake Bank

Mobile banking security researchers are actively engaged in identifying and thwarting various threats, including mobile app-based banking malware, trojans, phishing attacks, fake banking apps, and brute force attacks, primarily targeting FinTech apps. Among these threats, a significant concern is the emergence of fake banks, a type of spyware designed to monitor payment verification messages, or OTPs, sent by authorized banks to clients. When users of mobile banking receive verification codes, this spyware intercepts them and forwards them to cybercriminals.

Duplicate Flash Player

The Duplicate Flash Player is a deceptive video application introduced via predatory emails or installed files through infected SMS containing malicious download links. Once installed, this video app requests permissions and initiates the creation of a deceptive login screen. When users enter their credentials or bank login details, the malware copies and sends this information to a database accessible to malicious actors.


The Svpeng trojan, identified by Kaspersky Lab's senior malware analyst Roman Unuchek, poses a severe threat in the realm of mobile banking. This trojan can overlay itself on other mobile applications, access unofficial sources, conduct financial transactions, and gain permissions for message handling, contact reading, call-making, and device administrator rights. This multifaceted trojan presents considerable risks to mobile banking security.

App-Based Banking Trojans

Another category of mobile banking fraud involves app-based banking trojans. These trojans conceal themselves in seemingly unrelated applications, such as tools or games, that unwary users unknowingly download. Typically sourced from unofficial channels, these apps may harbor dormant malicious programs.
When a mobile user launches a banking app on their device, the trojan becomes active, generating a pop-up overlay on the bank's login page. Subsequently, when the user inputs their ID and password, the trojan intercepts and compromises the credentials on the banking app login page.

How To Improve Mobile Banking App Security

The Use Of SIM Cards With NFC Technology

The security of mobile applications has become a major concern due to instances of confidential information leakage, financial losses, and unethical hacking. Incidents involving the compromise of credit or debit card details have raised alarms, with malicious practices exploiting user data for future unauthorized use.

Additionally, the app notifies users in the event of changes to their savings account, such as a switch to a current or salary-based account, ensuring timely and effective communication.
Given the wealth of information stored in the application, each detail is interconnected. Therefore, it is imperative to link every transaction with its corresponding history, including the user's mobile number. This functionality enhances user awareness by providing transaction updates through various channels, such as emails, SMS, or phone alerts, ensuring that users stay informed about their financial activities in the most effective manner.

Use Behavior Analysis

The evolution of banking mobile applications has progressed significantly, becoming an essential requirement in today's landscape. Businesses are now actively involved in developing specialized financial accounting software tailored to the specific needs of banks and the broader financial sector. These applications store a myriad of details, including analysis of user behavior such as time spent on the app, login locations, saved passwords, and various account activities.
The user behavior analysis serves as a valuable asset, promptly flagging any unusual activities detected within the account. Development resources online automatically generate alerts for potential risks associated with the account, and real-time actions are taken accordingly. This auto-generated feature acts as a vigilant system, investigating any malicious practices and keeping users informed about any suspicious concerns that may arise.

Data Breach

The security of applications is consistently under scrutiny as hackers seek to compromise the private and confidential data of users. Data breaches pose a prevalent challenge for businesses in the current system, with statistics indicating that 36 billion records were exposed in the first half of 2020, according to RiskBased.
