How to Make a Secure Mobile Banking App?
With the development of high-speed Internet computing banks are starting to leverage modern security measures in order to prevent highly sensitive data of their customers from being breached. Learn how to build secure and reliable mobile banking app to provide an outstanding experience to your customers, while keeping out the cyberattackers and not compromising the speed and innovation.
Mobile Disruption Has Already Started
Everything has gone mobile. Gadgets are now the preferred devices. Extreme proliferation of smartphones, tablets, and wearables brought the idea of constant connectivity into the minds of consumers. People see their smartphones as omni-functional gadgets for everyday life, performing money transactions, buying goods and services, storing personal data like ID cards and passports.
As a result, methods of accessing information changed dramatically, including the most critical and the most vulnerable information – financial. A huge shift has happened in financial services as the recent technology revolution made it possible to perform transactions almost instantly.
Mobile Has Irreversibly Transformed Banking
The demand for state-of-the-art mobile services increased dramatically. The new generation of customers expects to do less and to have more. They want to have all their financial data on top of their fingers and manage their finances with a single touch.
Today’s market requires a modern banking system to leverage instant connectivity and total mobility. To answer new market needs banks are looking for advanced and exceptional methods to improve the quality of their services and exceed their customers’ expectations. Thus, banking services have migrated from banking branches and even from desktops to tablets and smartphones.
What a Good Mobile Banking App Needs to Be?
Before starting to develop a mobile banking app, you should ensure it meets all the customers’ basic needs and expectations and is going to be helpful and convenient.
The app should not be a one-to-one mapping of the features available in online banking. It should possess only the core features, made as easy as possible. The app should not be in any case overloaded with all the complicated functionalities, but have core stuff right, obvious and usable, like balance checking, quick and easy payments and transfers, and transactions history reviews.
Before you start developing a banking app, think about the features that are low on the app’s priority list and are easy to drop, and drop them. Deciding what not to do is as important as making up the list of features you are going to provide for sure.
Minimalistic Yet Attractive UI/UX
Don’t forget about the look and feel in the process of your mobile banking app development. Good UI/UX is integral to the process. Effective UX can be critical to the success of your application. Look closer at your potential target audience, carry out usability studies, conceptualize ideas, and write user stories to understand what users expect from your application. Build it with these results in mind.
UI/UX should add convenience to the app, not to detract from it. The app can benefit from pagination, animation, and other techniques that make it “live”, but too many bells and whistles will be abundant.
Incorporate key UI/UX principles:
- Intuitive navigation
- Customized experience based on the frequent transactions
- Consistency with all gadget sizes and platforms (iOS and Android)
- Set up notifications settings
- Pair your app with the online banking website
Now let’s dive into the most common banking activities users expect from m-banking apps.
- Create an account easily and quickly. Users prefer to complete the enrollment process from start to finish without even having to set their foot inside a branch.
- Check an account balance and recent transactions history. In the new era of technology, users don’t have to find the ATM to check the balance or ask the paper copy of transactions history in the branch.
- Person-to-person payments.
- Remote deposit capture using smartphone camera.
- Receive text messages and push notifications on the user’s activity, as well as alerts.
- Make bill payments (utility services, payments for mobile communications and Internet, electronic tickets).
- Locate the closest ATM or a bank branch.
- Get on-demand reports and summaries for user’s account activity.
Security is Paramount
So, you know what your mobile banking app should look like and what to fit in it. You’re half-way to provide an outstanding banking experience to your customers. Now put security on the forefront. Make it a top priority.
The last couple of years are infamous for notorious security breaches. Apps are getting smarter and smarter, and this opens wide doors before cybercriminals. Mobile opens up a large potential for data theft and fraud. The more customers access their banks through their gadgets – the more opportunities for frauds arise. Moreover, the imagination of cybercriminals has barely any limits. New methods of infecting mobile devices are expected to rise. What makes the ground so fertile for banking apps security breaches?
Mobile operating systems are vulnerable to bugs, viruses, and malware. Secure mobile application development requires a development team to have an extensive expertise in modern security practices. Unfortunately, only a few mobile banking app development companies are capitalizing on the possibility to gain a competitive advantage by offering strongly secure mobile apps. Still, a majority of customers are highly concerned about the security risks involved with mobile banking.
Key Threat Factors
- Jailbroken or rooted devices. Jailbreaking and rooting remove some of the security features and inherent limitations that keep mobile devices from passing information back and forth when they shouldn’t, and, thus, expose account information to extreme risk. Jailbreaking allows mobile malware and rogue apps infect the device and gain control over the critical functions such as SMS.
- Storing customers’ data on their phones, with obvious privacy implications. Anonymous developers create fake bank apps that attempt to exploit information on users’ devices in order to commit banking fraud.
- Sending activation codes for accounts through plaintext communication (HTTP) provides the cybercriminal with the possibility to intercept the traffic and hijack the session to steal the user’s account details.
- Outdated OSs and non-secure connections. Open Wi-Fi connections are not as secure as office firewalls. Anyone can watch a user typing a password, as well.
Ensure Solid Data Security
It’s critical to prevent security breaches in the early stages of mobile banking app development process. Timely identification of potential risks helps develop a product safely from start to finish of SDLC.
To drive this point further, here is what you can do to mitigate the most common flaws:
- Make sure your existing security policies are technologically enforced and are dependent on user compliance.
- Have a full thought-out security plan at every stage of application development.
- Build you app safely. Consider risk mitigation, security management, regulatory compliance obligations, and web-based/mobile application source code vulnerabilities prior to deployment.
- Two-factor authentication. Also known as two-step verification. The practice of sending an SMS with a one-time passcode every time the user tries to log in. The use of two-factor authentication (2FA) adds a significant layer of security to the application.
- Integrate the latest digital signature technologies into the mobile app to make all the transactions more secure. These mathematical techniques are used to ensure the authenticity, integrity, and nonrepudiation of a message. Digital signatures have the same legal significance as ink on paper signatures.
- Strong password protection and build-in password strength checker. The app shouldn’t allow the users to save their passwords. This is great for quick opening of the app, but this means someone who steals their phone has full access to their accounts. A strong password should contain a certain number of capital letters, symbols, special characters, and numbers. It should be impossible to guess.
- Auto log out after X seconds of inactivity.
- Incorporate security into the app development process. Last minute fixing may affect the whole functionality.
- Ensure that all connections are performed using secure transfer protocols.
- Improve additional checks to detect jailbroken devices.
- Remove all development information from the production app.
- Enforce SSL Certificate checks by the client application.
Threatened Men Live Long
In addition, one of the preventive security measures you should adopt is educating your customers about the security risks and best practices to follow. A well-informed customer using a mobile banking app can serve as an additional layer of protection in itself. Promote security among them as your core differentiator and remind your customers to:
- Password protect their smart devices
- Avoid saving login data
- Log out when they are done
- Set up SMS notifications on every transaction
- Provide them with official application, or inform where it can be downloaded
How to Pay Less and Get More
Having proper security onboard, mobile banking applications may be highly profitable. However, they are not only about money, they are about trust. Secure and reliable mobile banking app may serve as your best driver for customer acquisition. Keep in mind that costs incorporated with an attack can be much higher.
How much may cost the development of the mobile banking app? World’s leading banks spend approximately $132,000 for the development of mobile banking app from scratch. The middle-sized outsourcing company will charge you for the solution of this kind between $60,000 and $80,000, which can help you gain maximum benefits for a very reasonable price.
If you decided to leverage an outsourcing company and cut costs for the app development, contact the company you chose to identify the final price. Usually, mobile banking app development cost depends on the developers’ salaries and a number of working hours needed to complete the project. For example, the average hourly rate in the Eastern Europe is $35-50, as compared to US’ $100-150.
