eWallet applications have become household things.

Used by a large chunk of the population across the world, eWallet applications are responsible for trillions of dollars in transactions each year.

While they are known for their convenience and ease of use, this begs the question of whether they are safe. Well, eWallet app security is a big concern, especially for the service provider.

If you are one of the eWallet app companies who want to secure their solution or just want to learn more about the topic, this blog is for you.

Here, we shall be discussing everything you need to know about eWallet app security, common threats, best practices, trends, and more.

So with this being said, let’s get right into it:

The Ever Growing Threat of Cyber Fraud: A Global Security Crisis

Fintech statistics show us an ever-growing market, with trillions in market value and billions of users across the globe.

But what they also show us is the growing threat of cyber fraud. Let’s dive into it:

  • Globally, cybercrime costs businesses an estimated $6 trillion annually.
  • Financial institutions are the most targeted industry for cyberattacks, accounting for 20% of all attacks.
  • eWallet apps are a prime target for cybercriminals, with losses exceeding $1 billion in 2022 alone.
  • Phishing remains the most common type of cyberattack, accounting for over 80% of all reported incidents.
  • The average cost of a data breach in 2023 is $4.35 million.

The loss of these cyber-attacks is huge. But even if that’s not a justification for why eWallet app security is important, let us give you some more reasons in the section below.

Why eWallet App Security is Important?

There are lots and lots of businesses that want to create an eWallet app.

However, not everyone wants to invest in eWallet app security. That’s where the real trouble starts. “But eWallet security isn’t all that important is it?”

Hate to break it for you, but if you’re not investing in Digital Wallet app security, there’s a sword hanging over your head.

In fact, poor security is one of the reasons why most digital wallet app startups fail in market.

Importance of eWallet App Security

Let’s see why it’s so important to protect your mobile wallet, as a fintech company:

1. To Maintain Brand Image

If a company wants to market an eWallet app successfully and create a brand image that is sustainable, then eWallet app security is a topic of importance.

Any marketing company or even a company CEO would love to tell you about the importance of the brand image and branding itself. When we are talking about fintech apps like eWallets, the majority of brand image depends on the level of app security they offer.

The reason is that a company that’s losing money (customer’s money) to frauds and cyber threats, isn’t something a customer would like to associate with.

This is why, to maintain a brand image, eWallet app security is super important.

2. Drive Customer Loyalty

To make an app successful is to gain people’s trust and drive loyalty.

One of the best ways to boost customers’ confidence in the eWallet application and the business itself is by offering impregnable eWallet app security.

When the user base knows their money and high-value information is safe, they can use the app worry-free.

Ask yourself, have you ever worried about fraud when using top apps like PayPal? Exactly.

3. Being Compliant With Regulations

Fintech and the financial world alike are subjected to an endless number of regulations and rightfully so. One common theme that most of the regulations have in common is to deliver an ewallet with security to the end user.

This is a must for user and data privacy standards. Therefore, if an eWallet app needs to compete in the market, or exist in the market at all, doing this is very important.

4. Keep Revenue Stream Steady

eWallet monetization strategies will let you generate millions if done right.

But if you want to keep the stream steady and not lose money to fraud, it’s important to maintain a full proof platform. The reason is, a secure app will attract more customers and investors while deflecting all fraud attempts that snatch millions at a time.

After all, financial institutions like eWallet companies are the first target of fraudsters.

5. Remain Future-Proof

If you have been exploring fintech app development scenarios, you must have heard the word “future-proof” a lot.

Being future-proof means having a platform that is ready for the market of tomorrow. And to achieve this status, it’s important to make your eWallet secure.

So, these are the top reasons why it’s important to make your digital wallet secure. And with this out of the way, let’s look at some common threats to eWallet app security.

Common eWallet App Security Threats & Weak Points

To create a secure eWallet application, one must know of the threats that are lurking.

So, shining a light on that, we shall be going through some of the common eWallet app challenges and security threats in this section of the blog.

Common eWallet App Security Threats

So let’s get right into it:

Threat 1: Phishing Attacks

One of the most common types of security threats is phishing attacks.

For those who don’t know about phishing, the attackers try to obtain sensitive information by pretending to be a trustworthy entity.

Here’s how it works in the eWallet security world: deceptive messages, emails, or calls are sent to the customer, directing them to a fake counterfeit website that may look like their bank’s.

Here, once they enter their login credentials or personal information, attackers will use it to their advantage.

Due to the general lack of awareness and financial literacy among generations, it is one of the most harmful cyber-attacks. Companies across the world have launched their own financial literacy apps to tackle this problem.

Threat 2: Social engineering

This is a rather “none-technical” cyber threat.

Social engineering is when an attacker manipulates the user to gain their confidential information. This involves psychological games and tricks, and they are quite effective

In fact, there have been instances where people have impersonated someone and exploited the information out of eWallet company’s employees.

Threat 3: Communication Failure in APIs

To make an eWallet application work, a lot of Fintech APIs are used.

APIs or application programming interfaces establish communication between different components and it also involves the transfer of financial information.

More often than not, different components come from different companies which makes them less compatible with each other and leads to communication failure. This can lead to data leaks and other unwanted parties sucking on the data.

This is the reason why, making API security the most important e-wallet security measure.

Threat 4: Man-in-the-middle (MITM) attacks

Man-in-the-middle and MitM attacks are yet another common form of cyber-attacks that pose a big threat to eWallet app security.

Here’s how it takes place: the hacker will intercept communication between the devices and eWallet platforms. During these attack sessions, they will steal any important data they can get their hands on, including login credentials and payment information.

Threat 5: Malware and viruses

If you have been using a PC or any kind of computer, there is a high chance that you have already heard of malware and viruses.

These are malicious software and programs that can highly damage even the most secure eWallet. Malware and viruses are often disguised under the name of popular apps that users may want to download from third-party sites. For instance, app store or play store alternatives.

However, when they are installed, they attach themselves to smartphones and they are very hard to uninstall. Here, they will capture the user’s financial data as well as the user’s keystroke.

Threat 6: Account takeover (ATO)

The name says it all. Account takeover more popular known as ATO, is when the attacker gains access to a user’s account and locks them out of it.

Various methods can be used to gain unauthorized access, including social engineering. Speaking of which, once the user is inside the account, they will exploit the funds and transfer them to their account. They also steal their personal information.

Threat 7: QR code scams

In all popular eWallet applications like Google Play, Apple Pay, and Samsung Pay, we have something called QR code trigged payments.

This has become a common way to trigger contactless payments in recent years. And this also becomes one of the biggest threats to Digital Wallet security.

The reason is that hackers can create fake QR codes that, when scanned, can redirect users to phishing websites or download malware onto their devices.

Threat 8: Unpatched vulnerabilities

Creating an eWallet app is no easy task. More often than not, many bugs and errors are overlooked, leaving vulnerabilities.

These vulnerabilities are often targeted by hackers and used to damage the platform while also trying to gain access to user accounts.

This is a big issue that can be solved with regular app maintenance and support.

Threat 9: Weak authentication mechanisms

It goes without saying that eWallet apps should use strong authentication mechanisms, such as multi-factor authentication (MFA), to protect user accounts.

However, it should also be understood that weak authentication methods, like single passwords, are easily compromised by hackers. And that’s exactly what happens when there is a compromise in the secure digital wallet.

Threat 10: Third-party risks

In every app development process, a lot of third-party components are involved.

Similarly, eWallet apps often rely on third-party services, such as payment processors and data storage providers.

If these third-party providers are not secure, user data could be compromised.

Now that we are done with the common threats to eWallet security, it’s time to see how you can identify the same. Take a look at the audit process in the section below.

eWallet App Security Audit Process

The first step to making your digital wallet secure is to identify the vulnerabilities.

In order to do this, we have to conduct an audit to check eWallet app security. In this section of the blog, we shall be discussing exactly that.

eWallet App Security Audit Process

So let’s get right into it:

1. Scope and Planning

The first step to conducting an app security audit is, defining the scope. What do you want to audit? Is it the data storage or authentication process?

Once you have a scope, it’s time to select an audit methodology. For instance, it can be penetration or beta testing, vulnerability scanning, and so on.

In addition to this, the team needs to establish a timeline and budget.

2. Information Gathering

With the scope set and plan ahead, it’s time to start gathering information.

The team will gain access to information about the eWallet app, including architecture diagrams, source code (if applicable), system documentation, and security policies.

Plus, they shall also analyze the eWallet app design and implementation to identify potential vulnerabilities.

3. Vulnerability Assessment and Penetration Testing

It’s time to use automation testing tools to start vulnerability assessment.

One of the most important things that happens in this step is manual penetration testing. This is done to identify zero-day vulnerabilities and exploit potential attack vectors.

After testing, the impact as well as the severity of the identified vulnerabilities are assessed.

4. Security Code Review

Following the testing, it is time to review the eWallet app’s source code to identify coding errors and security weaknesses.

Following this, the team shall evaluate the use of secure coding practices and cryptographic algorithms. This is done to ensure compliance with industry best practices for secure coding.

5. Reporting and Remediation

With all said and done, it’s time to create a report.

The audit team shall prepare a comprehensive audit report documenting identified vulnerabilities, their severity, impact, and remediation recommendations.

Following this, it’s time to make the necessary changes to ensure the vulnerabilities are fixed. Here, banking app developers have to prioritize vulnerabilities based on their risk level and develop a plan for remediation.

Finally, it’s time to implement remediation measures to address identified vulnerabilities.

This is how you identify gaps in Digital Wallet security measures. Based on the audit report, it’s time to introduce eWallet app security features. Let’s just look at just that in the next section of the blog.

Top Security Features of a Digital Wallet

One of the top tips to improve eWallet security is to introduce features that compliment app security at all levels.

eWallet app features play an important role in ensuring impregnable security. Take a look at some of the top wallet app features that help ensure total security.

Top Security Features of A Digital Wallet

These are, as mentioned below:

Feature 1: Secure Login and Sign-Up Process

If you want to know how to protect your digital wallet app, the first thing that you get to learn is secure onboarding.

It goes without saying that, the client side is the most vulnerable part of an eWallet platform. In fact, if the user is not verified, they can be a huge security threat.

This is the reason why to secure your digital wallet app, the platform must have a secure login and signup process.

Feature 2: Biometric Authentication

Throughout the blog, we have read how important authentication is in mobile wallet security. Well, one of the best authentication features is: biometric authentication.

This functionality has been in mobile phones for years [now. For instance, a fingerprint scanner on Android devices for unlocking or the popular FaceID for facial scans in recent iPhone models.

Biometrics are unique to every human and pretty difficult to bypass that’s what makes it a top eWallet app security feature.

Feature 3: Passwords

A password is the most basic mode of protection, which must be used by every personalized website or app.

Adding a rejection feature that activates when the password is too short or easy to guess will make your app more secure and safe.

Biometric security can also be added if the smartphone contains a fingerprint sensor. This is a key component of a secure wallet app.

Feature 4: P2P Encryption

P2P Encryption is a very robust security tool that helps in protecting the debit or credit card transaction process.

As soon as you swipe a card on the PoI (Point of Interaction) terminal, it will start encrypting your debit or credit card data until the final transaction is completed.

This is a very useful fraud prevention tool to implement if you are trying to ensure eWallet security with robustness.

Feature 5: Geofencing

Geofencing integration in the eWallet application ensures the app can know the location of the user.

Here’s how it helps you secure your digital wallet securely: whenever there is an unauthorized transaction, it will not be approved as it won’t match the location of the user’s current location.

This is often used in eWallet apps like Google Pay. Therefore, if you are planning to level up the eWallet app, make sure to improve this feature.

Feature 6: Tokenization

With the help of this technology, seamless eWallet security has become a reality.

Tokenization disconnects the buyer’s sensitive data from the end receiver through the use of mapped tokens, which the receiver uses to process the buyer’s credit card payment.

As soon as the user enters the card details to make payments, the card details are encrypted and turned into tokens that look similar to a random number.

Feature 7: Contactless Payment

Contactless payment is one of the eWallet app trends that has been changing the market. This has been seen in top NFC payment apps and how they have become so popular.

Well, apart from the convenience value and its aesthetic appeal, contactless payment technology is also great for promoting eWallet app security. Communication via NFC technology is much faster and more secure since all the data is encrypted.

Furthermore, when being used via a phone, it is next to impossible to commit physical fraud which is often the case with credit cards and debit cards.

Feature 8: Two-Factor Authentication

What better than one layer of app security? That’s right, two layers.

This brings us to one of the top tips to improve digital wallet security i.e. introducing a two-factor authentication feature.

What this does is, in addition to the usual authentication layer, another one is added which can be activated via OTP or biometric.

Since it is already hard enough to bypass one layer, getting through two is next to impossible physically.

Feature 9: MFA – Multi-Factor Authentication

Well, if you want to take the authentication process to the next level when enhancing your digital wallet security, consider MFA.

It stands for multi-factor authentication. Here, the user is required to pass two or more layers of authentication to verify their identity and make a transaction possible.

Whether you want to create an app like Cash or the usual eWallet, this is a top feature that you should definitely consider.

And with this out of the way, let’s look at some of the top technologies used to secure an eWallet application.

Top Technologies For eWallet Security

If you have an idea for the eWallet app that you want to bring to reality or want to update the current legacy system to improve the eWallet app security, here’s a tip to follow.

App tech stack plays an important role in the function and working of the app. Take a look at some top technologies to add to your tech stack to make sure there are no vulnerabilities.

Top Technologies For eWallet Security

1. Blockchain is a very important Technology for eWallet Security

The use of blockchain development expands far beyond cryptocurrencies. Digital wallets integrated with blockchain technology are extremely safe, secure, and immutable when compared to other solutions.

This technology is preferred mostly by financial organizations and government agencies due to the high level of security associated with blockchain.

Blockchain is also very enticing to these large organizations due to the extra features that blockchain technology offers, such as decentralization and being able to offer tokens

2. NFC Technology Useful for eWallet Security

The NFC or Near Field Communications allow users to transfer funds without sharing their contact details. This technology deals with easy data exchange between closely located devices.

NFC mobile payment allows users to make payments directly with their smartphone – instead of payment cards. Some of the successful examples of NFC are Samsung Pay and Apple Pay.

In addition to this, NFC also allows the transfer of funds by simply touching one smartphone to another smartphone. This is one of the trusted e-wallet tech.

3. Bluetooth and Beacon Technology useful for e-wallet Security

Are eWallets safe?

Well, when filled with mobile payment application security like Bluetooth, yes, they are.

This allows you to identify nearby devices that you can make a payment to. This is a very fast and secure technology to use for transferring funds digitally.

You can transfer funds to other users who are close to you or who are in the prescribed transfer range. The best part is that this technology doesn’t even ramp up eWallet app development cost too much.

4. QR code is currently trusted by eWallet Security Technology

QR Codes are generally used for making payments or transferring funds to other members of the public.

It is also used to make payments with contacts that are not saved in the user’s phone already. To make a payment, users just have to scan the QR code of the receiver.

This technology is one of the smoothest and most simplified ways of making payments.

With all that said and done, let’s look at some of the best practices to secure your digital wallet in the next section of the blog.

Best Practices to Secure Your Digital Wallet
