Explore the different types of payment fraud and become aware of telltale signs and how to prevent them.

Payment fraud is growing in scale and sophistication, affecting businesses across every industry, and as digital payments expand, so do the opportunities for bad actors to exploit vulnerabilities. Understanding how fraud works and how to prevent it is essential for protecting revenue, maintaining trust, and staying resilient in an increasingly complex threat landscape.

What Is Payment Fraud?

Payment fraud refers to the theft of money from businesses or individuals through unauthorized transactions or deceptive purchases. Fraudsters may act using their own accounts or by gaining unauthorized access to someone else's account.

While payment fraud can happen in person, online transactions are especially vulnerable. According to Juniper Research, global business losses from online payment fraud are projected to surpass $362 billion between 2023 and 2028. A business's fraud risk depends largely on its industry, the sensitivity of the data it handles, and the payment methods it accepts. The more ways customers can interact with accounts and complete purchases, the more entry points exist for bad actors to exploit.

Different Types of Payment Fraud

Fraudsters use many tactics, and below we list 14 of the most common. Given the large number of threats, businesses must prepare their teams to recognize a variety of warning signs. Strong internal communication policies, clear escalation procedures, and knowledge of the landscape are foundational to any fraud prevention strategy.

1. Phishing

Phishing is a social engineering tactic in which criminals attempt to trick people into revealing sensitive information such as account credentials or payment details. These attacks often come in the form of malicious links sent via email or text, but they can also occur over the phone. Attackers may pose as trusted figures - a friend, a bank representative, or a government official - to manipulate victims.

Prevention tips:

Let customers know exactly how your business will contact them, including phone numbers and email addresses.

Be transparent about what information your staff will and will not ask for.

Alert customers to any known phishing attempts targeting your brand.

Train employees on information security protocols and how to identify suspicious communications.

2. Credit and Debit Card Fraud

This type of fraud involves obtaining card information - either physically or digitally - and using it to make unauthorized purchases. Cards may be stolen directly, or details may be harvested through card skimming devices installed on ATMs or point-of-sale terminals. Attackers also acquire card data through phishing schemes or by purchasing stolen credentials on the dark web.

Prevention tips:

Restrict POS system access to authorized personnel and regularly inspect payment hardware for tampering.

Build secure, encrypted payment pages that comply with data protection standards.

Offer customers multiple notification options for purchases and account activity.

Warn customers never to share account or confirmation numbers with unverified sources.

3. Wire Transfer Fraud

In wire transfer fraud, criminals convince victims to send money directly to them. Because wire transfers are difficult to reverse, they are a preferred method among scammers. Attackers commonly impersonate someone the victim trusts - a family member, a company executive, or a business vendor. The use of a convincing back-story is often referred to as "social engineering." For example, an attacker may text employees pretending to be their CEO, claiming an emergency and requesting an urgent fund transfer.

Prevention tips:

Train employees to spot the signs of social engineering and impersonation.

Establish official communication channels and avoid conducting financial business over easily spoofed channels like text messages.

Report and share all phishing attempts with the entire team.

4. Check Fraud

Check fraud involves using counterfeit or altered checks to make payments or writing checks from accounts that lack sufficient funds. Fake checks may be digitally printed or modified versions of real checks. In some cases, the check is genuine but drawn from a closed account.

Prevention tips:

Implement software that verifies the authenticity of checks.

Train staff to recognize the visual and physical signs of fraudulent checks.

5. Chargeback and Refund Fraud

Also known as "friendly fraud," chargeback fraud occurs when a customer makes a legitimate purchase and then falsely claims a refund - either directly from the business or through their credit card company. This type of fraud is particularly tricky because it can be hard to distinguish from genuine disputes, especially when delivery or service quality is involved.

Prevention tips:

Validate customer information, including billing addresses and card security codes.

Use payment platforms that include fraud protection and dispute automation tools.

Respond to refund and chargeback requests quickly.

Minimize legitimate chargebacks by fulfilling orders accurately and on time.

6. Identity Theft

Identity theft happens when a criminal obtains someone's personal information and uses it for financial gain or to make purchases in someone else's name. For businesses, a common result is having to deal with chargebacks after customers discover fraudulent charges on their accounts. Although the primary victim is the customer, businesses have a responsibility to prevent data breaches that expose customer information in the first place.

Prevention tips:

Train employees to recognize phishing and follow secure information handling practices.

Ensure your payment systems comply with PCI DSS (Payment Card Industry Data Security Standard) requirements.

7. Account Takeover Fraud

Account takeover (ATO) fraud typically follows identity theft. Once attackers obtain a user's credentials, they change the password and contact information to lock the real owner out. From there, they may use the account for fraudulent purchases or sell it to other bad actors.

Prevention tips:

Enforce strong password requirements for all accounts.

Require two-factor authentication (2FA) and send confirmation alerts for any significant account changes.

Notify customers of purchases and account modifications in real time.

8. New Account Fraud

New account fraud (NAF) occurs when someone uses stolen or fabricated identities to open new lines of credit or accounts. These fraudulent accounts can then be used to make purchases or commit further fraud down the line.

Prevention tips:

Require multi-factor authentication (MFA) - not just email verification - during account creation.

Verify address details and card security information during transactions.

Use fraud protection tools that leverage machine learning to detect unusual account creation patterns.

9. Gift Card Fraud

Gift card fraud is a social engineering scam where criminals pressure victims into purchasing gift cards and handing over the card numbers. Once the numbers are given, the funds are essentially unrecoverable, making this a popular method among scammers.

Prevention tips:

Display warnings about gift card scams during the checkout process.

Remind customers never to share gift card numbers with people they don't personally know.

Educate in-store staff to recognize signs of gift card fraud and when to escalate the situation.

10. Merchant Identity Theft

In merchant identity theft, attackers impersonate legitimate businesses or vendors to defraud customers or partner organizations. They may use phishing to extract employee credentials and gain access to business systems, or they may pose as a trusted vendor and redirect payments to themselves.

Prevention tips:

Train staff to identify phishing attempts and follow secure communication practices.

Establish verification procedures when communicating with vendors and business partners.

Report phishing attempts to employees and partners promptly.

11. Pagejacking and Domain Spoofing

Pagejacking involves cloning an existing webpage and redirecting users to the fake version to steal login credentials or payment information. Domain spoofing follows a similar concept - attackers build an identical-looking site under a slightly different URL. Users are typically directed to these fraudulent pages through malicious emails or texts.

Prevention tips:

Run plagiarism detection tools to identify duplicate versions of your pages online.

Pay attention to unusual customer service complaints that might signal a spoofed site.

Submit takedown requests to search engines if you discover a duplicate site, and notify affected customers.

12. Mobile Payment Fraud

As mobile payments become more prevalent, they've also become a target for fraud. Attackers can exploit mobile apps through malware installation, stolen app credentials, or interception of 2FA codes. For example, a scammer may call a customer pretending to represent a business and ask them to read back a verification code - which is actually a 2FA code the attacker has triggered on the victim's account.

Prevention tips:

Authenticate customers over the phone carefully to reduce the risk of impersonation-based fraud.

Monitor for unusual spending or refund activity in mobile transactions.

Educate customers about the risks of clicking on unknown links, QR codes, or visiting unfamiliar websites.

13. Push Payment Fraud

Unlike unauthorized transaction fraud, push payment fraud involves tricking the victim into willingly sending money to a fraudster. This can take many forms, including phishing, blackmail, or deceptive scenarios like fake emergencies. The key distinction is that the victim actively initiates the transfer.

Prevention tips:

Clearly communicate to customers what your staff can and cannot ask them to do or pay.

Make it easy for customers to report anyone impersonating your business.

Issue proactive alerts about ongoing scam attempts tied to your brand.

14. ACH Payment Fraud

ACH (Automated Clearing House) payment fraud involves criminals gaining unauthorized access to a victim's bank account details and using them to initiate fraudulent transfers. For businesses, this risk can come from both outside attackers and malicious insiders.

Prevention tips:

Strictly limit and monitor employee access to business bank accounts.

Educate all staff with account access about phishing tactics and establish firm security policies.

Which Businesses Have the Highest Fraud Risk?

Not all businesses face the same level of exposure. Fraud risk is generally highest in sectors that process online payments, handle sensitive personal data, or still accept paper checks.

E-Commerce Businesses

E-Commerce businesses are particularly vulnerable. Online retail involves accepting payments from a wide range of locations, often with multiple payment methods. Features like peer-to-peer payment integrations or international checkout add more potential points of failure. The more accounts and payment methods a customer has linked, the more attractive a target they become for data breaches.

Healthcare, Banking, and Data-Sensitive Industries

These sectors are at elevated risk because of the high value of the information they store. A breach in these sectors doesn't just expose financial data - it can compromise identity information used to commit fraud across many platforms simultaneously.

Businesses Still Accepting Checks

These kinds of businesses face unique challenges. As check usage declines, employees may become less experienced at identifying fakes, which makes training and verification systems all the more important. According to the Association for Financial Professionals, check fraud remains one of the most common forms of payment fraud.

How to Mitigate Risk

A variety of tools and strategies are available to help businesses identify and reduce fraud exposure. Conducting a security risk assessment is a strong starting point, helping teams understand which vulnerabilities are most critical and where to prioritize investment.

From there, organizations should focus on establishing a solid operational and security foundation before layering in more advanced fraud detection capabilities.

Foundational Controls

These measures create a baseline level of protection by securing systems, safeguarding data, and reducing avoidable losses:

Strong network and password security: Establish internal policies governing account access, password requirements, and physical access to devices and systems.

Network tokenization: Ensure payment systems encrypt and tokenize customer data to protect sensitive information.

PCI standards compliance: Build payment workflows that meet Payment Card Industry (PCI) standards to safeguard cardholder data.

3D Secure (3DS) authentication: Use the latest 3DS protocols to validate transactions and verify user identity before completing purchases.

Chargeback protection: Work with your payment processor to implement tools that help minimize financial losses from disputed transactions.

Once these core protections are in place, businesses can enhance their fraud prevention strategies with more dynamic, data-driven approaches.

Advanced Detection & Optimization

These techniques improve visibility, adaptability, and long-term resilience against evolving fraud tactics:

Fraud KPI tracking: Monitor key metrics such as dispute rates, authorization rates, and approval/decline ratios to identify trends and respond proactively.

Rules-based systems: Implement rule-based detection as a reliable operational backbone. While rules require ongoing maintenance, they are especially useful in early stages and can be refined over time.

Machine learning algorithms: Leverage ML-powered systems to analyze large, complex datasets and uncover patterns that are difficult to detect manually. These models continuously improve as they adapt to new fraud behaviors.

Staying Ahead of Payment Fraud

Payment fraud is an ongoing challenge, but a proactive, layered approach can significantly reduce risk. By combining strong foundational controls with data-driven detection and continuous monitoring, businesses can stay ahead of evolving threats.

Ultimately, effective fraud prevention requires regular review, employee awareness, and a commitment to adapting as tactics change.
