What is payment fraud? What faster payment systems mean for fraud prevention

Payment fraud: What is it and why the payment system used matters 

Payments are evolving, and so are fraud tactics. As digital transactions become faster and more convenient, fraudsters are finding new ways to exploit vulnerabilities across payment channels. Financial institutions must stay ahead by implementing proactive fraud detection strategies to protect their customers and mitigate losses.

Key topics covered in this post: 

Understanding payment fraud

Payment fraud refers to unauthorized or deceptive transactions designed to steal funds, manipulate accounts, or exploit weaknesses in payment systems. Fraudsters leverage a variety of tactics to move illicit funds quickly through payment systems before detection.

Financial crime professionals have developed many best practices for detecting and preventing payment fraud committed using traditional payment methods such as Automated Clearing House (ACH) transactions, checks, wire transfers, and card networks. But customer expectations are shifting toward instant transactions, and new and less familiar payment technologies are gaining traction. For example, FedNow and The Clearing House’s Real-Time Payments (RTP) Network allow banks and credit unions to send and receive instant payments 24/7, while blockchain-based payment systems like Ripple or stablecoins offer faster, decentralized transactions.

How fraud is committed across traditional and emerging payment systems

Financial criminals continuously adapt their methods, taking advantage of system vulnerabilities and human error. Some of the most common payment fraud tactics include:

  • Check fraud – Altering, forging, or counterfeiting checks to illegally access funds. 
  • Wire fraud – Impersonating account holders or businesses to divert wire transfers to fraudulent accounts.
  • Account takeover fraud – Gaining unauthorized access to customer accounts through phishing, credential stuffing, or malware.
  • Mule networks – Using individuals or businesses to move stolen funds, often under the guise of legitimate transactions.

New and faster payment systems have some advantages over the more traditional systems that fraud teams have monitored for decades. For example, no checks or cards means less opportunity for criminals to steal valuable customer information from these physical items. However, with faster payments comes greater fraud risk. The Federal Trade Commission (FTC) reported that in 2024, U.S. consumers lost over $12.5 billion to fraud, a record high and a 25% increase over 2023. Unlike traditional transactions that allow time for review and reversal, instant payments mean that fraudulent transfers can be executed and withdrawn within seconds, making recovery difficult​.

What's more, convincing account holders to authorize fraudulent transactions through confidence scams is a social engineering tactic that does not discriminate based on payment system. Fraud schemes that rely on building relationships with victims first are perhaps more dangerous when employed alongside payment systems that conduct instant transactions, giving victims less time to think about their actions and financial institutions less time to question them. The use of new technology like generative AI in fraud scams has made deceptive communication even more difficult for unsuspecting customers to detect.

Payment fraud prevention strategies

To safeguard transactions and reduce fraud risks, financial institutions should implement a multi-layered fraud prevention approach. This includes real-time monitoring, behavioral analytics, and adaptive fraud controls that can detect suspicious patterns before a transaction is completed. The following strategies are part of an effective approach:

  1. Leverage real-time fraud detection software – Implement AI-driven fraud monitoring that analyzes transaction patterns and flags anomalies instantly.
  2. Enhance customer authentication – Strengthen multi-factor authentication (MFA) and biometric verification to prevent unauthorized access.
  3. Educate customers and staff – Regularly train employees and account holders on recognizing phishing, scams, and fraud tactics.
  4. Monitor high-risk transactions – Set transaction limits and review outbound payments, especially in high-risk corridors.
  5. Use data-sharing networks – Collaborate with industry fraud prevention networks to detect known fraud patterns and block fraudulent transactions before they occur.

Identifying red flags in payment behavior

So, what does payment fraud look like in practice? Here are some common indicators that may point to fraud when analyzing customer activity:

  • Unusual transaction patterns: Spikes in volume or frequency, especially outside of normal business hours or locations.
  • Lifestyle mismatches: Transactions that don’t align with a customer’s known spending habits, such as luxury purchases on a previously frugal account.
  • Geographic anomalies: For example, a transaction in Boston followed 15 minutes later by one in California.
  • Excessive chargebacks or non-sufficient funds (NSFs): Especially for accounts with no prior history of such issues.
  • Check hiding or kiting behaviors: Moving funds rapidly between accounts to simulate available balances.
  • Inconsistent or manipulated customer information: Repeated changes in names, addresses, or phone numbers across applications or accounts.
  • Evidence of coercion: Customers appearing nervous or being influenced by third parties—either in-person or over the phone—during transactions.

Distinguishing whether the customer is the victim or perpetrator is critical, as red flags may present differently depending on the situation. 

Collaborating across teams to fight fraud

While anti-money laundering (AML) software and fraud detection platforms like Abrigo Fraud Detection help identify abnormal activity, human oversight remains essential.

Front-line staff are uniquely positioned to recognize red flags in customer behavior. Clear escalation procedures and cross-department communication are vital for a well-rounded fraud prevention program. Financial institutions should also review past fraud incidents to identify gaps in current controls. 

Regulators expect financial institutions to employ adequate technology and human resources to manage evolving fraud scams and risks. In a payment fraud webinar, Abrigo advisors recommended investing in the following:

  • Updated hardware: Apply updates and patches in a timely manner and use multi-factor authentication (MFA) and biometric verification to prevent unauthorized access.
  • Advanced fraud detection: – AI-driven fraud detection and monitoring solutions analyze transaction patterns to identify anomalies in all types of payments. Machine learning models continuously adapt to new fraud typologies.
  • Enhanced employee training – Ensure ongoing education and training across your institution. Frontline staff need to be able to recognize phishing attempts, deepfake scams, and synthetic identity fraud, along with variants as they emerge.
  • Customer or client awareness campaigns: Providing fraud education through special seminars, newsletters, and digital campaigns can reinforce best practices for spotting scams and reporting suspicious activity to fight payment fraud.

Payments will only become faster and more digital in the future, and payment fraud is likely to follow suit. With the right approach and technology, fraud teams can keep up with emerging payment fraud methodologies and keep their customers safe.
