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.
Transactions
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.
Investments
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.

Multi-factor authentication involves the use of multiple verification points to ensure the authenticity of customers. The concept is designed to fortify security by introducing additional layers beyond just a single password. Unlike relying solely on a password, MFA incorporates various elements such as face recognition, fingerprint scans, and one-time passwords.
The primary purpose of multi-factor authentication is to create a more resilient defense against unauthorized access. If one authentication factor is compromised, the presence of additional layers makes it significantly more challenging for hackers to breach security. This multifaceted approach enhances the overall safety of customers, providing a comprehensive defense against potential cyber threats and unauthorized access to sensitive financial information.
End-To-End Encryption
Digital transactions involve two essential parties: the sender and the receiver. In everyday scenarios, numerous individuals, including regular customers, retailers, cards, payment brands, and issuing banks, actively participate in transactions through mobile apps and financial mobile payment gateways.
Given the prevalence of these transactions, where billions of dollars worth of confidential data are exchanged regularly, the risk of cybercriminals targeting internet purchases is a significant concern. To safeguard consumers from potential threats, businesses must implement robust security measures, such as encrypting transactions.
End-to-end encryption emerges as a practical solution to address the substantial challenge of securing sensitive data. This method ensures the security and integrity of data throughout the entire transaction process. By overseeing safety checks and assessments, end-to-end encryption serves as a crucial measure for protecting businesses from fraudulent activities and unethical users.

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.
In the face of widespread data breaches, the safety of information is paramount. Mobile banking applications, which store both personal and business data, have become attractive targets for hackers due to their access to user passwords, account numbers, and other sensitive credentials.
Confidential information stored on mobile devices is particularly vulnerable, as mobile file systems are susceptible to hacking. It is crucial to enhance security by installing applications specifically designed to protect data from various types of breaches.

This proactive approach is essential for mitigating the risks associated with data breaches and safeguarding sensitive information effectively.
PSD2’s Financial Consequences
The Payment Services Directive (PSD2) in the European Union has undergone revisions, particularly introducing multi-factor authentication for online payments within the region. Under PSD2, financial institutions overseeing payment accounts are mandated to validate internet transactions, including card purchases, through two-factor authentication (2FA). This enhanced authentication method combines elements the user knows, such as a password or PIN, with something the user possesses, like a code generated by a mobile app or a biometric identifier.
The implementation of this online payment mechanism for international trade aims to bolster the security and protection of transactions conducted between two bank accounts. The banking application, adhering to PSD2 regulations, prohibits any third-party entities from accessing customer information without explicit consent. This additional layer of security within the mobile banking application serves as a safeguard against potential fraud, ensuring the confidentiality and integrity of user data.
