Contactless Payment Scams

Contactless Payment

Contactless payments through cards are hugely popular within the UK – in fact, they’ve now overtaken chip and pin payments. Contactless payments increased by 30% between June 2017 and June 2018 – and 52% of all shop payments were contactless in July 2018. Overall, there were 7.4bn contactless payments in 2018.

Around 7 in 10 payments in the UK are contactless, and 17% of 25 – 34-year-olds make only one monthly payments using cash – or rely entirely on cards to make payments.

One of the reasons for the increased popularity of using contactless cards is they’re easy and simple to use to pay for a variety of goods. By removing the need for a PIN code, contactless cards do offer a fast and convenient way to pay – however, they may also offer criminals the opportunity to commit fraud.

Below, we look at the facts behind contactless cards, how fraudsters can take advantage and the best ways to avoid becoming a victim of credit card fraud.

How do contactless cards work?

Contactless cards contain both a chip and an antenna that is used to carry out the transaction. When you hold your card on or near a card reader, the retailer’s card reader sends out a signal which is picked up by your card’s antenna. The chip inside your card contains information about your account and by using this information, the card reader can process its payment.

Payments are currently limited to a maximum of £30 (it was previously £20), and are typically used for small retail purchases. There can sometimes be a problem with “card clash” which is when two contactless cards, either payment cards or travel cards like Transport for London’s Oyster Card, both interact with a card reader at the same time.

Contactless payments are also quicker because payments are processed in batches.

How widespread is contactless card fraud?

It may seem like contactless technology allows fraudsters an easy way to access your money without a PIN. Assuming you take precautions to protect your card, the chances of it happening to you are reduced – however, consumers are right to be vigilant as cases of contactless card scams doubled in 2018.

Because contactless payment technology currently limits the value of purchases, the total potential value of fraud involving these cards is reduced. Thieves are always looking for big payouts, which are limited by contactless scams.

However, there’s also been recent research that shows that the £30 maximum spend on contactless cards can be bypassed. Researchers have found that the flaws in the payment system for some contactless cards could potentially allow criminals to steal hundreds of pounds in a single transaction.

The hack the researchers used to “break” the £30 limit uses a device that intercepts the signals between the card and the card reader. It then simultaneously ‘tells’ the card that no verification is needed and the card reader that verification has been provided.

Another purported method that fraudsters use is to actually process payments by standing near someone on a train or in another crowded public place and reading their contactless card through their clothes. However, according to Which? there’s little evidence that this type of fraud is common.

How does Contactless Payments Fraud Happen?

While contactless payments offer convenience, they also present opportunities for fraudulent activities. Understanding the various methods used by fraudsters is essential in mitigating risks associated with contactless transactions.

  • Skimming and Cloning

Skimming involves the unauthorized capture of card information using hidden devices installed on payment terminals. Fraudsters can then clone the card or use the stolen information for unauthorized transactions.

  • Data Breaches

Data breaches occur when hackers infiltrate payment systems or databases, gaining access to sensitive customer information. This stolen data can be used to perpetrate fraudulent activities, including unauthorized contactless transactions.

  • Detecting Contactless Payments Fraud

Detecting fraudulent transactions in real time is crucial for minimizing financial losses and protecting personal information. Implementing robust fraud detection mechanisms can help identify suspicious activities promptly.

  • Transaction Monitoring

Utilizing advanced algorithms and machine learning algorithms can aid in monitoring transaction patterns and detecting anomalies indicative of fraudulent behavior. Real-time alerts can be triggered for further investigation and intervention.

  • Card Security Features

Modern payment cards are equipped with security features such as dynamic CVV codes and tokenization, enhancing protection against fraudulent transactions. These features add layers of security that make it more challenging for fraudsters to exploit vulnerabilities.

Preventing Contactless Payments Fraud

Prevention is key in combating contactless payment fraud. By implementing proactive measures and best practices, individuals and businesses can significantly reduce the likelihood of falling victim to fraudulent activities.

  1. Enable Two-Factor Authentication

Enabling two-factor authentication adds an extra layer of security by requiring users to provide additional verification, such as a PIN or biometric data, for completing transactions. This helps mitigate the risk of unauthorized access to payment accounts.

  1. Regular Security Updates

Staying vigilant and keeping payment devices and software up to date with the latest security patches and updates is crucial for addressing known vulnerabilities and safeguarding against potential threats.

  1. Understanding Contactless Payments Fraud

Understanding the intricacies of contactless payment fraud empowers individuals and businesses to take proactive steps in protecting themselves against financial losses and identity theft. By staying informed and implementing robust security measures, we can collectively combat fraudulent activities and foster a safer digital ecosystem.

How to avoid and report contactless card fraud?

Contactless card fraud is on the rise; in the first half of 2018, thieves stole more than £8 million from contactless scams.

You can minimize the chances of becoming a victim of contactless fraud by following these steps:

  • Don’t keep your cards in easily accessible pockets or bags which will draw pickpockets’ attention.
  • Line your wallet or cardholder with tin foil to block scamming devices from reading your card. If you don’t fancy the DIY approach, there are products like RFID readers available that do the same thing.
  • Don’t let anyone take your card out of sight while taking a payment – even for just a few seconds. They could be using a skimming device to copy data from your card’s magnetic strip.
  • Don’t give your friends your card to make payments – always make sure you’re there for all transactions.
  • Ask for a receipt to make sure you were charged the correct amount.
  • Keep a close eye on bank statements and your credit report to look for any unusual activity.
  • Report any lost or stolen cards as quickly as possible. There is a limit on how many times you can use a contactless card before requiring a PIN, which stops criminals from carrying out a large volume of small transactions of up to £30 each – however, it’s best to not wait for the card to be blocked.

What is Third Party Risk Management?

Third-party risk management (TPRM) is a type of risk management program that focuses on identifying and reducing risks that come with the use of third parties. Third parties that open businesses to risk are vendors, suppliers, partners, contractors, or service providers.

The risk management program aims to give organizations an understanding of the third parties they use. TPR programs are dependent on the type of organizations, the industry they operate in, and several other factors. But, several TPRM practices are universal and applicable to every business.

Third-party risk management often encompasses all the practices that help businesses prevent third-party risks and fraud.

In this guide, we’ll go over what is third-party risk management and common TPRM practices businesses can use.

Importance of Third-Party Risk Management

Third-party risk management has been around for a long time. However, l with recent growth in third-party fraud cases has increased the need for third-party risk management.

Disruptive events have impacted thousands of businesses globally. Moreover, several data breaches have been directly related to poor third-party risk management.

Some of the most common ways businesses can be impacted are:

  • Internal outages and slowing down operational capabilities.
  • External outages affect areas such as the supply chain.
  • Vendor risks that make your business vulnerable to supply chain fraud. 
  • Operational shifts that affect data gathering, storage, and security.

Almost all organizations today use some kind of third-party provider to keep their operations running smoothly. So, when there’s an issue with your third-party suppliers, your business suffers greatly.

Let’s say you’re using a cloud platform such as Amazon Web Services (AWS) to host your website. If AWS goes down for a couple of hours, your operations also go down.

Outsourcing is crucial for the success of modern businesses, it not only saves businesses money, but it also helps in getting help from experts.

Unfortunately, there’s a downside. If proper third-party risk management programs aren’t in place, the use of third parties can leave your business open to several risks.

Best Third-Party Risk Management Practices

Businesses can use several third-party practices that help you build a better program, regardless of where your business currently stands. Here are the 3 best practices that apply to almost every company.

1. Prioritize Your Inventory

Not all vendors are equally important for your business, this is why you need to determine which third-party vendors matter the most. To improve the efficiency of your third-party risk management program, you need to segment your vendors. 

You can segment the vendors into 3 categories:

  • Low risk, low criticality – Tier 3
  • Medium risk, medium criticality – Tier 2
  • High risk, high criticality – Tier 1

Generally, organizations will focus their time and resources on tier 1 vendors first, as they require more stringent due diligence and evidence collection. Tier 1 vendors are subject to the most in-depth assessments, which often include on-site assessments.

A lot of times, during the initial evaluation, these tiers are calculated based on the inherent risk of a third party. Inherent risk scores are generated based on industry benchmarks. These include:

  • Sharing proprietary or confidential business information with the vendor
  • Sharing personal data with the vendor
  • Serving critical business functions
  • Sharing sensitive personal data with the vendor
  • Sharing personal data across borders

The impact of a vendor can also be a determining factor. Let’s say a third-party vendor is unable to deliver their service, how much impact will that have on your business? When there is significant disruption in your operations, the vendor will also be higher. Businesses can figure out the impact by considering these factors:

  • The impact of unauthorized disclosure of information
  • Impact of unauthorized modification or destruction of information
  • Impact of disruption of access to the vendor/information

Another way to determine the impact of a vendor’s inability to deliver their work is by grouping based on contract value. Vendors that have huge budgets may automatically be segmented as tier-1.

2. Leverage Automation Whenever Possible

Efficiencies only happen when operations are consistent and repeatable. There are several areas in the third-party risk management process where businesses need automation. Some areas where businesses can use automation include:

  • Intaking and onboarding new vendors

Businesses can add vendors to their inventory by using an intake form or via integration with contract management or other systems.

Solutions like DIRO online document verification can help businesses in verifying vendor identity during onboarding. This helps in reducing vendor risk significantly.

  • Calculating inherent risk and tiering vendors

During the vendor onboarding process, businesses need to collect vendor information that helps in calculating the level of risk the vendor poses for the business.

Based on the level of risk, businesses can set up different levels of due diligence for vendors. This helps prevent fraud that comes with poor third-party risk management.

  • Assigning risk owners and mitigation tasks

Whenever a vendor is flagged, route the risk to the correct individual and include a checklist of mitigation action items. 

  • Triggering vendor performance reviews

You need to set up automation tiggers that conduct reviews of vendors during specific times of the year. The reviews could be each quarter, every 6 months, or once a month.

  • Triggering vendor reassessment

Businesses should send an assessment based on contract expiration dates. Businesses should also save last year’s assessment answers so vendors don’t have to start completely from scratch.

  • Scheduling and running reports

Businesses should set up automated reports that run every day, every week, or every month. These reports must be shared with the right person.

Every third-party risk management program is unique, so as a business, you need to start by looking internally at the small processes that can be automated.

3. Think beyond cybersecurity risks

Whenever businesses think of third-party risk management or vendor risk management programs, they think of cybersecurity risks. But, third-party vendor management is far more than cybersecurity risks.

While it is important to focus on small things and consider cybersecurity risks, there are other types of risks that businesses should prioritize, such as:

  • Reputational risks 
  • Geographical risks 
  • Geopolitical risks 
  • Strategic risks 
  • Financial risks 
  • Operational risks 
  • Privacy risks 
  • Compliance risks 
  • Ethical risks 
  • Business continuity risks 
  • Performance risks 
  • 4th party risks 
  • Credit risks 
  • Environmental risks
