What Technologies Make Online Money Transfers Secure?

A 2022 report by the Bank for International Settlements suggests that about $7.5 trillion is transferred daily around the globe.

For context, the U.S. federal government spent $7.01 trillion in its 2025 fiscal year, which ran from October 2024 to September 2025, according to the U.S. Treasury Fiscal Data.

Basically, this implies that about 7% more money is traded on the foreign exchange market daily than the U.S federal government spends annually.

As you would expect, digital platforms that serve as channels for the movement of large volumes of money on a daily basis are bound to be affected by various risks, including transfer fraud, phishing, data theft, man-in-the-middle attacks, and even fake apps.

In fact, losses due to these risks pile up as you consider various payment channels/segments. Juniper Research, for instance, suggests that losses due to online payment fraud alone will exceed $362 billion by 2028, with 2028 accounting for at least $91 billion. Thus implying that these losses are only going to increase over time.

What should this mean for you?

Well, the world has already gotten to the point where it’s nearly impossible to do away with online payments. Therefore, your best bet is to protect yourself.

After all, as malicious entities are refining their techniques, fintechs are equally developing innovative technologies that power the safety of online transfer in money transfer apps. For additional online safety, you should go for fintech apps that use innovative technologies behind the scenes to secure online transfers.

This article explores the key technologies and protocols that protect online money transfers that you should look out for in fintech apps, from encryption to biometric ID.

Key Technologies That Keep Transfers Safe

Below are seven key technologies that have been proven to keep transfers safe globally:

1.End-to-end encryption (E2EE)

IBM describes end-to-end encryption as a “secure communication process that prevents third parties from accessing data transferred from one endpoint to another.”

Fundamentally, E2EE technologies encrypt data being sent from one end, ensuring that it is only the intended recipient at the other end that can decrypt it.

Uses and How It Works

End-to-end encryption is typically used in communication, collaboration, and financial tools.

The aim is to protect sensitive data traveling through a given communication channel or financial network from the prying eyes of intermediaries, third parties, and malicious actors on different nodes in the network.

With money transfers, for instance, let’s suppose that you want to initiate a money transfer to Ecuador. E2EE technology ensures that all sensitive transaction details (including bank account and credit card info) and personal details are protected throughout the entire transaction, protecting your privacy.

2.Two-Factor & Multi-Factor Authentication (2FA/MFA)

Two-factor authentication (2FA) and multifactor authentication (MFA) are enhanced verification methods that require users to provide two or more factors to verify their identity to gain access to their account.

2FA systems typically require two factors, while MFA systems may require more than two factors, depending on user settings.

Uses and How They Work

Any organization or entity can embed 2FA or MFA in its system to secure access control. However, it’s more widely used by financial services, email services, and cloud storage services.

2FA and MFA systems work by requesting the provision of information across three main authentication factors:

• Something you know, typically a PIN, password, or security questions.
• Something you have, such as an authenticator app or a unique device for receiving an OTP.
• Something you are, usually your biometrics, including fingerprint, iris scan, or facial scan.

Any combination of these factors can ensure that an unauthorized person doesn’t get access to your fintech account—or any other account for that matter.

3.Tokenization

Tokenization is a security method that involves replacing sensitive data with a non-sensitive equivalent called a “token”, which provides no real value to the viewer.

Like E2EE, tokens help mask sensitive data until they get to their destination, but unlike E2EE, they cannot be deciphered.

Uses and How It Works

Tokenization is typically used in financial services to provide enhanced data security for credit card information and social security numbers.

It is a key requirement of Payment Card Industry Data Security Standard (PCI DSS) compliance, which aims to ensure the security of digital transactions.

In payment processing, tokenization broadly involves three steps:

• Token generation: Sensitive data is sent to the tokenization system, which generates a random token to replace it.
• Token vaults: The sensitive data is sent to a token vault, where it basically becomes inaccessible unless the token is mapped back to it.
• Payment processing: The token, now replacing the sensitive data, serves as a placeholder for the sensitive data throughout the rest of the transaction.

4.Secure Sockets Layer / Transport Layer Security (SSL/TLS)

SSL and TLS are foundational security protocols that provide secure communication over the internet, typically between web browsers and web servers or between two servers.

Secure Sockets Layer protocols are predecessors to Transport Layer Security Protocols, which provide more advanced cryptographic keys for protecting your activities over the web.

Uses and How They Work

Together, SSL and TLS are used to create secure and trusted communication over the internet, especially on websites.

SSL/TLS-compliant websites are usually indicated by “https” and a padlock icon, signifying that sensitive data you input on the website, such as login details, credit card numbers, or other personal information, is protected.

SSL/TLS provides encryption, authentication, and data integrity by enabling your browser to obtain and verify a server’s certificate, ensuring that a supposed financial website is authentic before exchanging your information with it.

5.Fraud Detection & AI Monitoring

Fintech apps are leveraging AI and machine learning to implement real-time, system-wide fraud monitoring, detection, and prevention during payment processing.

These systems can continuously learn from old and new data and adapt to emerging threats, establishing their role as more advanced, proactive fraud detection technologies.

Uses and How It Works

AI security systems in finance apps are used to provide 24/7 monitoring of user accounts to detect anomalies even in the absence of human oversight.

AI monitoring works by:

• Learning and understanding the unique behaviors of a given user, including typical transaction volumes and other account activities.
• Flagging any activity that deviates from the usual behavior, such as initiating the transfer of large amounts to an unfamiliar location.
• Automatically halting the transaction or all account activities if necessary, until the real user provides additional authentication factors.

This helps prevent fraudulent activities on accounts around the clock.

6.Biometric Authentication

Biometric technologies in fintech include fingerprint scanning, facial recognition, iris scans, typing patterns, and voice recognition, which are unique physical and behavioral identifiers for gaining access to a user account.

Due to the high level of uniqueness attached to biometrics, they are generally considered to be more secure than PINs and passwords.

Usesand How It Works

Biometric authentication is typically used alongside password-based authenticators to create a 2FA/MFA approach that provides a higher level of security.

Biometric authentication works by:

• Obtaining and securing a biometric template: The system obtains the user’s biometric data/template during enrollment and stores it for future reference.
• Authentication: Upon subsequent logins, the system takes a fresh scan of the biometric data and compares it to the stored template. It only grants access if the new scan matches the template.

Activating biometric authentication on your account can greatly enhance the security and integrity of your account. Modern fintechs are also improving the reliability of their biometric authenticators by integrating “liveness detection” in their systems to limit spoofing.

7.Compliance & Regulation Technologies

There are various types of compliance and regulation technologies in fintech, including Know Your Customer (KYC) and Anti-Money Laundering (AML) technologies.

These technologies help ensure that both customers and financial service providers meet all relevant requirements for initiating or processing a transaction.

Uses and How It Works

Fintechs use AI in KYC systems to reduce false positives and speed up high-quality verification when collecting foundational identity data when onboarding a user. AI in AML systems ensures 24/7 continuous monitoring for suspicious activities during transactions using the KYC database.

AI-powered compliance and regulation technologies are crucial for monitoring efforts, as they can sift through millions of transactions quickly to spot indicators of crime, detect anomalies, establish links of fraudulent activities, and cross-check databases to determine a user’s identity using a diverse range of parameters.

These technologies are often governed by PCI DSS, GDPR, and similar regulations, which contractually force fintech services to ensure the security of customer data during transactions.

What Users Can Do to Stay Safe

Given that technologies are making online money transfers more secure, users will be generally safer when they use apps that integrate the above-mentioned technologies.

In addition, they should:

• Choose secure platforms with clear privacy policies.
• Enable all security features at their disposal, including 2FA, MFA, and app lock.
• Keep apps updated to get the current security patches for their fintech app.
• Be cautious with public Wi-Fi and phishing emails. If an email looks suspicious, delete it. right away; don’t open it.

These additional steps can go a long way to protect your account from phishing, identity theft, man-in-the-middle, and other malicious attacks.

Conclusion

As much as fintechs are doing their best to make online money transfers more secure, the user has a greater role to play in protecting their accounts by staying vigilant and cautious.

Above all, it is absolutely important to always choose trusted platforms that invest in strong security technologies across all their platforms, including web, desktop, and mobile apps.
