Card payment fraud cost UK businesses a staggering £551.3 million in 2023, and this figure continues to grow steadily. When considering how to get a card machine for your business, understanding these security risks should be your top priority.
As contactless payments surged by 30% between June 2017 and June 2018 (with 52% of all shop payments being contactless by July 2018), thieves managed to steal more than £8 million through contactless fraud in just the first half of 2018. Furthermore, businesses face additional risks with card-not-present transactions, where merchants often bear liability for fraudulent telephone payments and online transactions processed without 3-D Secure.
In this guide, we’ll examine how fraudsters exploit vulnerabilities in payment systems, recognize early warning signs of potential fraud, and implement practical protection measures. We’ll also explore how selecting the right card machine with enhanced authentication mechanisms can significantly reduce your fraud risk, protecting both your revenue and reputation.
How Card Payment Fraud Happens in Real Life
Fraudsters are becoming increasingly sophisticated in their approaches to card payment scams. Remote purchase fraud, where stolen card details are used online, surged 22% in 2024 and has become the most common attack vector. This rising threat requires businesses to understand exactly how these scams operate in the real world, a concern that makes understanding How to Get a Card Machine from a reputable provider a fundamental step in building a secure payment environment.
Common fraud scenarios in UK businesses
UK businesses regularly encounter several prevalent fraud types. Card-not-present (CNP) fraud accounts for approximately 70% of total card fraud losses and occurs when transactions happen without physical card verification. “Friendly fraud” or chargeback scams have increased from 15% in 2023 to 36% in 2024, where customers falsely claim they didn’t authorize legitimate purchases.
Another concerning trend involves counterfeit cards, where criminals use skimming devices to steal card data from point-of-sale terminals. Additionally, businesses face refund fraud, where fraudsters exploit lenient return policies using stolen payment methods.
Social media platforms account for nearly three-quarters of online fraud cases, primarily because they provide criminals easy access to potential victims.
How fraudsters exploit weak points
Criminals constantly search for vulnerabilities in payment systems, policies, and procedures. One increasingly common tactic involves tricking customers into disclosing one-time passcodes sent via text message. Once obtained, these codes allow criminals to authenticate fraudulent online transactions despite Strong Customer Authentication requirements.
For in-person payments, researchers have exposed concerning weaknesses in contactless EMV payment systems. In one striking example, they demonstrated how a payment terminal could be tricked into accepting a fraudulent £25,000 transaction.
Moreover, fraudsters increasingly use social engineering to manipulate victims. This approach proves more effective than traditional identity theft, which dropped by 26% to £58.7M as businesses improved their detection systems.
The role of online and in-person transactions
In-person transactions face different risks than online ones. Card-not-received fraud, where cards are intercepted after issuance but before reaching the legitimate cardholder, grew 13% between January and June 2024. Meanwhile, lost and stolen card fraud increased by 30% to £100.2 million.
In contrast, online environments present unique challenges. Nearly 2.6 million remote purchase fraud cases were logged in 2024—equivalent to more than 7,000 incidents daily, or almost five every minute. Furthermore, six in ten UK adults now use mobile banking apps, which has sparked an increase in mobile banking fraud cases to a record 9,590 in the first half of 2024.
Consequently, businesses must implement different security strategies depending on whether they primarily process online or in-person payments.
Recognizing the Warning Signs Early
Detecting payment fraud early can save your business thousands in potential losses. Skilled fraudsters leave behind telltale signs that, once recognized, can help prevent financial damage. Let me show you what to watch for before approving that next suspicious transaction.
Unusual order patterns or high-value purchases
Transactions significantly larger than your average order value should immediately raise concerns. Criminals with stolen cards typically try to maximize purchases before the theft is discovered. Furthermore, orders containing multiple identical items in different colors or sizes often indicate fraud, as these goods can be quickly resold for cash. I’ve found that genuine customers rarely purchase high-value items without asking questions, whereas fraudsters rush through expensive purchases without hesitation.
Mismatch in billing and shipping details
A billing and shipping address mismatch represents one of the most common fraud indicators. Although legitimate reasons exist (like sending gifts), this discrepancy warrants investigation. Essentially, shipping to P.O. boxes, freight forwarders, or non-residential addresses makes an order particularly suspicious. For instance, many fraudsters use these locations as reshipping points to receive packages without detection.
Multiple failed payment attempts
Watch closely for customers making several payment attempts in quick succession. This pattern typically indicates “card testing,” where criminals try multiple stolen cards until one works. According to security experts, transactions involving different cards from the same IP address—especially several orders submitted around the same time—should be flagged for review. Multiple declined transactions followed by a successful one almost always signals fraudulent activity.
Customer reluctance to provide ID
Genuine customers rarely object to verification requests. Conversely, if someone struggles to provide basic personal information like their address or full name, this strongly indicates fraud. Similarly, watch for spelling errors or inconsistencies in submitted information—these often reveal hastily created false identities. Above all, remember that a customer who cannot establish their connection to the delivery recipient presents a significant red flag.
Practical Steps to Protect Your Business
Protecting your business from card payment fraud requires implementing several strategic security measures. With criminals successfully stealing around £1.2 billion from UK businesses in 2018 alone, these practical steps have become essential rather than optional.
Use card machines with built-in fraud protection
Modern card machines come equipped with sophisticated security features that significantly reduce fraud risk. Initially, look for terminals with point-to-point encryption (P2PE), which makes customer card data extremely difficult for fraudsters to access. Card machines with EMV technology add an extra layer of security, while solutions from payment providers typically include advanced fraud-fighting tools that minimize PCI compliance complexity.
Enable 3D Secure for online payments
3D Secure (3DS) adds a crucial verification layer for online transactions, connecting three entities: your bank, the card issuer, and the protocol’s infrastructure. Primarily, this protocol enables data exchange between merchants and issuers to validate that transactions come from legitimate cardholders. As a result, businesses gain liability protection—if a properly authenticated 3DS transaction later proves fraudulent, the financial responsibility shifts from your business to the card-issuing bank.
Limit manual entry of card details
Manually entered card details present substantially higher fraud risks. In fact, once chip and PIN or contactless payments are approved, sellers typically aren’t liable for fraudulent transactions. However, manual entry, magnetic stripe swiping, or signature verification methods expose your business to potential losses. Whenever possible, insist on secure payment methods like chip and PIN or contactless.
Train employees on fraud awareness
Fraud awareness training equips staff to recognize different fraud types and respond appropriately. Certainly, designating specific fraud awareness responsibilities to named job roles helps create accountability. Training should cover:
- Recognizing red flags in everyday transactions
- Understanding the three types of fraud defined in the Fraud Act 2006
- Proper reporting procedures for suspicious activity
Set up alerts for suspicious activity
Implement systems that flag unusual patterns, potentially saving thousands in losses. Track geographical locations through IP address monitoring, plus analyze transaction data sets to identify irregular behaviors. Consider joining the NCSC’s Early Warning service, which provides free alerts about potential cyber attacks on your network using information from trusted sources.
What to Do If You Suspect or Experience Fraud
Discovering fraud requires swift action to minimize financial damage and protect your business reputation. Knowing exactly what steps to take can mean the difference between recovering funds or suffering significant losses.
How to report fraud to your payment provider
Contact your payment provider immediately upon discovering suspicious transactions. Report the fraud within 13 months of the unauthorized payment to maintain your refund rights. Many banks require notification within two business days to limit your liability to $50. When reporting:
- Gather transaction details before calling
- Request card blocking or replacement
- Ask about temporary refunds during investigation
- Follow up in writing to document your claim
Documenting and preserving evidence
Thorough documentation strengthens your case for financial recovery. Create a dedicated folder labeled “fraud evidence” containing:
- Screenshots of suspicious transactions
- Communication with suspected fraudsters
- Transaction receipts and confirmation numbers
- Timeline of events in chronological order
Backup this evidence securely, as it may be needed months later during investigations.
Notifying affected customers
Transparency builds trust during security breaches. Develop a communication strategy with your legal team that balances customer awareness against potential reputational damage. Provide clear guidance on protective steps customers should take.
Working with law enforcement
File a police report promptly to document the incident officially. Law enforcement may require this report for their investigation. Additionally, report the fraud to Action Fraud at 0300 123 2040, providing all relevant transaction details. Remember that law enforcement plays the primary role in crime prevention.
Reviewing and updating your fraud policies
After the incident, conduct an internal investigation to identify security gaps. Implement corrective actions promptly based on findings. Consider enrolling in additional fraud prevention services like ACH Debit Block or Positive Pay.
