Introduction to Mobile Banking Security

Mobile banking is a quick and easy way to handle your finances, including checking your balance, transferring funds, paying bills electronically, and more. When your mobile application is facilitating so many activities, it is massively important for us to make it secure and scalable as per user needs. 

Looking at the importance of mobile banking applications, we decided to bring before you the factors that contribute towards making mobile banking security a priority. The role of confidentiality security in mobile banking applications is extremely important. Keep this in mind when creating your own banking app. So let’s take a look at some of the more popular mobile banking security issues. We will also discuss some points on how to deal with them using new technology and approaches. And how leading financial software development company – TatvaSoft can help in that.

1. Advocate the Use of SIM Cards with NFC Technology

There is a lot of buzz around the security of mobile applications as there are many instances of confidential information leakage or financial loss non-ethical hacking. There have been incidents when using credit or debit card details are leaked or hacked. Many other malicious practices conceal the user data and use their financial records in the future. 

When users are unable to go out in uncertain times, mobile banking is the safest option available. Not just this, there has been the incorrect practice of hacking the details from the cookies stored in mobiles or desktop. No security is assured. Therefore, customers are reluctant to perform web and mobile app support services through their mobile phones.


To save your enterprise from such unknown leakage of confidential information, we advocate the use of SIM cards in Credit and debit. Customers can easily download their credit card data onto their Near Field Communication SIM card using a SIM card embedded with NFC. This is another alternative to protects their account data in general, It enables you to carry a card and use it if your SIM card is nearby. It improves mobile banking security and eventually improving the performance and reliability of the app.

2. Add a Multi-factor Authentication Feature in the App

The best part of financial business is that it has quickly taken up the pace and traversed from paper banking to paperless banking. So in this process of transformation, there are many security checkpoints established by banks and banking software development companies. These points are called multi-factor authentication. By name, we have understood that there are multiple points assigned to check the authenticity of customers

Why do we need a multifactor authentication feature? Multi-factor authentication is like security checkpoints where if there is access to one password, the rest cannot be hacked. In other cases, the one password is a link to several other passcodes and hence mobile banking systems have come up with several other options in defense. With this feature, there are will be many security blocks the hacker has to go through like face recognition, fingerprint, and One-time password. This is an extra layer added to the safety of customers to protect them from breaches or hacks.

3. End-to-end Encryption to Save Information Leakage

When you perform digital transactions, there are two parties always involved – Of course one is the sender and another is the receiver. Like in an everyday instance, we see many people doing regular transactions through mobile apps or financial mobile payment gateways. Everyday users such as normal customers, retailers, cards, payment brands, and issuing banks play critical roles. 

Every day, every year, billions of dollars worth of confidential data are shared. As a result, internet purchases have become a target for cybercriminals. To save consumers from this, it is important for businesses to encrypt the transaction. 

End-to-end encryption is a viable alternative to this enormous problem because it guarantees data security and stability. It is in charge of organizing safety checks and surveys. This is a safety measure for protecting businesses from fraud and unethical users.

4. Introduce Fingerprint Device in-app

For the safety of businesses, there have always been discoveries and innovations. Another vital innovation of the 21st century is the advent of fingerprint recognition. This is another safety layer for mobile apps. This saves the accounts from getting hacked by adding some layers. It is made taking into consideration fro multiple aspects such as browser, IP address, screen size, location, time, device type, location, and others. A fingerprint scanner is installed in the smart devices and it safeguards the information of users in the system itself. So let us assume that the device has your personal information and it gets into the hands of a hacker. What to do? Well, you don’t have to worry about it since it is sealed with your fingerprints details.

When your business develops a mobile banking application like this, your need to ensure that the details are sealed and there is no chance of data leakage. Your developers must know how to integrate this feature within the applications developed. Users from all domains- insurance, mortgage, eCommerce, retail, or any other industry can use this.

5. Real-time Report via Phone or Email Alerts

When you develop a banking app, there are various features apart from the safety ones that a business demands. The banking app offers businesses a fully-featured mobile application. Hence, this includes mobile banking facilities with loans option, mortgage services, personal loans, private loans, home loans, interest rates, online banking, credit card information, and similar other details. In case you have changed your savings account to current or salary-based accounts, it will let you know. The system ensures that every info is timely communicated in the best way possible.

With all this inevitable information stored in the application and each of these details is interlinked. Thus, when you develop the app link every single transaction with the history. This will also add the mobile number of the user. The addition of this functionality keeps the user informed about the transaction via emails or phone alerts. It could be an SMS or through phone calls.

6. Make Use of Behavior Analysis

The development of banking mobile applications has come a far way from where it started. It has now become the need of the hour. Businesses develop software applications that are tailor-made as per the needs of the banks or financial sector needs of businesses. There are numerous details that are stored such as analyzing the time spent on the app, login locations, saved passwords, and other account activities.

This behavior analysis of the user is in favor and they raise a flag whenever there is any unusual activity taking place. Risks associated with the account are timely raised by the development resources online and necessary actions are also taken in real-time. This is an auto-generated feature that investigates all the malicious practices. It also informs the user of all types of suspicious concerns.

7. Data Breach

The security of applications is always questionable with hackers invading the private and confidential data of users. The data breach is one of the common challenges that businesses deal with in the existing system. If we go by the stats, Data breaches exposed 36 billion records in the first half of 2020.-RiskBased

When there is a data breach occurring for every business information, no data is safe. Hence we have to develop applications that safeguard our information is of great importance. Mobile banking applications store both types of data personal and business. They have ready access to users’ passwords, account numbers, and other credentials that hackers would like to have. 

When placed on a mobile computer, such confidential information cannot be adequately secured. Mobile file systems are easy to crack. Installing security applications that secures your data from all types of the breach. Furthermore, without a strong defense, an opponent only needs a range of advanced instruments.

 The Solution

The only way here is to stop relying on the standard way of development kits, find other secure data. Keep most of the information encrypted by using modern encryption algorithms that can be decrypted when the need arises.

8. PSD2’s Financial Consequences

The European Union has revised the Payment Services Directive (PSD2), which includes multi-factor authentication for online European payment. With this law, PSD2 requires financial institutions that maintain payment accounts to contest internet transfers made by users, such as card purchases, through two-factor authentication (2FA).  This better authentication blends what the user recognizes, like a password or PIN, with something the user has, like a code created by a mobile app or a biometric identifier.

This online method of payment for international trading was brought to effect so that the transaction becomes more secured and protected between two bank accounts. This banking application will not allow any third-party company to get information about the customer with his/her consent. So this is an added security to the mobile banking application to protect them from fraud.

Conclusion- The Secure Way is to Hire a Professional Programmer

We know that innovations in technology are occurring at an unprecedented speed. The use of smartphone mobile banking has made banking go digital. The advancements have also given a rise to cyber crimes and thus users are reluctant in utilizing the technology. As a rescue, the banking sector is growing with innovation and has developed the discussed developments in the field of mobile banking application securities. To sum up, the above-mentioned features with the help of app development companies will help customers curb the majority of all the security challenges to overcome frauds.
