Payment Fraud Detection and Prevention: Here's All To Know
Key takeaways: With AI technology, payment fraud and fraud prevention have become more complex and sophisticated. Both financial data owners and businesses that accept illegal payments are directly affected by payment fraud. The best payment fraud prevention strategy requires careful risk assessment, planning, implementation, incident response preparation, and documentation. What is payment fraud? Payment fraud is the unauthorized use of an individual’s financial information to conduct illegal transactions. The overall strategy is to deceive individuals into sharing their financial and other sensitive information using hardware and software hijacking technology. Payment fraud happens when devices such as scanners, keystroke loggers, and malware capture manually entered data to divert the information back to the perpetrators. Businesses invest significantly in payment fraud prevention tools to counter these attacks. Types of payment fraud With today’s technology, every payment method is unfortunately at risk of fraud. We discuss them briefly below: Credit card fraud According to a 2025 Nilson Report, global payment card fraud losses reached $33.83 billion in 2023, with the US bearing approximately 42% of these losses. The most prevalent type of credit card fraud happens remotely: card-not-present (CNP) fraud, which occurs when stolen card information is used to make purchases online or over the phone. While EMV chip technology has reduced card-present fraud, criminals still find ways to exploit merchant vulnerabilities, often involving cloning, where criminals copy card details onto a blank magnetic stripe card or stolen cards used before the victim notices and reports them. Example: In November 2024, a UK resident’s replacement credit card was intercepted and used fraudulently before she received it, underscoring the vulnerabilities in card issuance and delivery processes.

This happens via physical theft of the card, skimming devices capturing card details, or data breaches exposing card information. Unlike credit card fraud, victims of debit card fraud may experience immediate financial loss as funds are withdrawn directly from their accounts. Example: In October 2024, a UK resident discovered unauthorized transactions exceeding £100 on their Uber and Uber Eats accounts linked to their debit card. Uber refunded the fraudulent charges, but it was unclear where the unauthorized transactions came from. Mobile payment fraud Mobile payment fraud occurs when fraudsters exploit mobile payment systems, apps, or devices to make unauthorized transactions or steal financial information. One way this is done is through SIM swapping, where an attacker gains control of a victim’s phone number to access their accounts, or through malware that infects a device to intercept sensitive information like payment credentials. Example: In November 2024, three Indiana residents were charged in connection with a nationwide SIM-swapping conspiracy. The defendants managed to steal funds and personal data through the mobile numbers connected to the victims’ email, social media, and cryptocurrency accounts. See: Mobile Device Security Policy Wire fraud Wire fraud involves schemes conducted via phone calls, emails, or online messaging platforms, often using false representations or promises to defraud individuals or organizations of money or property. Fraudsters trick victims into transferring funds to accounts they control, leading to substantial financial losses. Example: In July 2024, individuals based in Michigan, Illinois, and Texas pleaded guilty to conspiracy in international mail and wire fraud, defrauding victims of at least $2 million from 2017 to 2022. Check fraud Despite declining check usage due to digital payment methods, check fraud remains common. This involves illegal activities such as forging signatures, altering check details, or depositing counterfeit checks. Example: In late 2024, JPMorgan Chase filed lawsuits against customers who exploited a viral “money glitch” by depositing large, fake checks via ATMs and withdrawing funds before the checks cleared. This scheme resulted in over $660,000 in losses for the bank. Bank fraud Bank fraud involves schemes to steal cash and other bank assets, such as loan fraud, account takeover, fraudulent wire transfers, and embezzlement. Criminals may carry out these types of fraud using stolen identities, forged documents, or insider access. Example: In December 2024, reports emerged of low-level bank employees selling client data to online scammers, facilitating sophisticated financial fraud schemes. Staffers in various banks made copies of customer financial information, which they then sold to buyers on Telegram. Payment fraud strategies The different types of payment fraud involve various deceptive practices aimed at stealing financial data for unauthorized use. Here are seven of the most common ways payment fraud happens: Phishing Phishing is when scammers impersonate legitimate entities to trick individuals into revealing sensitive information. This deception is often carried out using fake emails, text messages, or websites that appear legitimate. How to detect phishing Watch out for unsolicited communications requesting personal information, generic greetings, grammatical errors, and URLs that deviate slightly from authentic addresses. How to prevent phishing Implementing email filtering solutions can help identify and isolate potential phishing attempts. Multi-factor authentication (MFA) adds an extra layer of security, and employees should be trained to recognize phishing emails. Skimming Skimming is when criminals install devices on ATMs or point-of-sale terminals to illicitly capture card information during legitimate transactions. These devices read the magnetic stripe data, enabling the creation of counterfeit cards for fraudulent use. How to detect skimming Signs of skimming devices include loose or misaligned card slots, unfamiliar attachments on payment terminals, or visible adhesive residues. How to prevent skimming Upgrade to payment terminals that support EMV chip technology, which is more secure than magnetic stripe systems. Additionally, install tamper-evident seals and conduct routine checks on all payment devices. Identity theft Identity theft involves the unauthorized access and use of someone’s personal information — such as Social Security numbers, bank account details, or credit card numbers — to commit fraud or theft. How to detect identity theft Consider installing monitoring services that can identify unusual account activities, such as unrecognized transactions, changes in account details, or unexpected credit inquiries. How to prevent identity theft Implement layers of identity verification processes,, such as biometric data and MFA. Update and patch systems regularly to protect against data breaches. Train
