What is payment fraud and how to prevent it

Payment fraud is any transaction that is carried out in order to deprive a person or business of money, property, or sensitive information. A common form of this is when a person, who's not the legitimate owner of the payment instrument, initiates a payment with the intention to commit fraud.

New fraud techniques emerge all the time and it's important to stay on top of emerging fraud trends to ensure your risk strategy remains effective. Here's a breakdown of the six main types of payment fraud:

Credit card fraud

Credit card fraud involves the use of stole card details to make purchases or simply withdraw money from the account associated with that card.

How to detect and prevent credit card fraud:

• Perform an AVS (Address Verification Service) or CID (card identification) check on transactions to verify the payment location and that the card is present.

• Apply behavioural analytics technology that flags suspicious activity, like someone repeatedly purchasing the same item, multiple purchases with the same email, or orders delivered to the same address using different payment details.

Card testing fraud

Card testing is the process of testing stole cards to see if they still work. Card details sold on the dark web are worth much more if they've been tested.

Card testing is especially prevalent in digital, low-value or even zero-amount transactions like those used to sign up for subscriptions or free trials.

How to detect and prevent card testing fraud:

• Apply behavioural analytics technology to identify fraudulent checkout attempts.

• Know your shoppers’ behaviour to ensure you’re blocking the correct scenarios.

• Use velocity checks to monitor the time-frame of orders. Card testers often use bots/scripts to test large batches of cards at once. If the transaction was too fast to be done by a human, it probably wasn't.

Account takeover fraud

Account takeover fraud is a form of identify theft in which a shopper's store account is breached. Fraudsters can then make changes to the account, make purchases using saved payment details, or create lookalike websites to steal the credentials of other shoppers.

How to detect and prevent account takeover fraud:

• Use timeline visualisation to understand the normal behaviour of genuine shoppers and how they differ after account takeovers have taken place.

• Ask for verification once account details are changed, for example when a shipping address is changed.

Friendly fraud

Friendly, or First Party, Fraud is when a shopper initiates a chargeback despite having received (and intending to keep) the purchased goods.

How to detect and prevent friendly fraud:

• Make sure your risk system can recognise patterns that identify serial friendly fraudsters, such as shoppers who have initiated multiple service-related disputes across different cards and identities.

• Use blocked lists to make sure those bad shoppers don't return.

Refund fraud

Refund fraud is a tricky one since it's very hard to spot and it's on the rise. It occurs when a fraudster requests a refund from a business. They then fail to return the order or return a different product.

How to detect and prevent refund fraud:

• Make sure your risk system has Unified Commerce capabilities so you’re able to fully understand the lifecycle of a shopper and view their past orders to identify refund fraud.

• Use a combination of unique attributes and leverage custom risk rules to mitigate such scenarios and identify unique shoppers misusing those details.

Gift card fraud

Gift card fraud is pretty easy to commit since gift cards are hard to trace and don't have the stringent regulations debit and credit cards are subject to. A fraudster might use stole card details to buy a product online and then return it for a refund or a gift card.

How to detect and prevent gift card fraud:

• Use contextual data to help build a much stronger defense against gift card fraud.

• Use a combination of custom risk checks and block lists based on this data to help spot these types of transactions.

• Identify misuse of gift cards by using custom risk rules and specified indicators to mitigate such events.

Payment fraud comes in many guises and it evolves all the time. So how do you stay on top of it?

One approach is to put security at the forefront; keep your defences high and block anything remotely suspicious. The challenge is when genuine customers inadvertently behave in ways algorithms identify as 'suspicious'. Blocking these transactions will lead to frustration, a lost sale, and possibly even a lost customer.

Every business (and customer) is different and risk management needs to be tailored to each unique set of challenges. Here's how to strike a sustainable balance between risk and revenue through detecting, preventing and responding to fraud.

• Detect: Recognise genuine customers and spot fraudsters across all your sales channels.

• Prevent: Maintain full control and reduce operational workload by combining risk rules with machine learning.

• Respond: Increase your authorisation rates and reduce chargebacks by adapting and optimising your risk setup.

Detect

Fraud detection technology

Fraud detection technology uses historical and cross-platform data between businesses to detect behavioural abnormalities and determine which customers are genuine and which are fraudsters. Configurations can also be made for specific high-risk segments, such as specific industries or geographic regions with higher fraud rates.

Prevent

Supervised machine learning

Supervised machine learning involves a combination of risk knowledge and machine learning. Businesses can create risk profiles to help automate part of the risk assessment, saving time and reducing risk management efforts.

Customisable risk rules

Different industries and businesses face different risks. Through customisable risk rules, businesses can create risk profiles tailored to their unique risks and use them as a base in the payment evaluation process to determine which transactions should be blocked and which should be accepted.

Authentication

Fraudsters often use identity theft to commit fraud. To make sure a customer is genuine and not a fraudster, businesses can verify them through 3D Secure 2.

Manually review

Certain types of transactions are at a higher risk of being targeted by fraudsters, these include high-value transactions or transactions in high-risk markets. For an extra layer of fraud protection, businesses can manually review these types of transactions before they’re completed to avoid a chargeback.

Respond

Testing and experimenting

No one knows the best risk management approach for their business until they test it. To find out what works for you, configure different risk settings and A/B test them against each other to see which approaches are the most effective for your business.

Although the techniques to commit fraud are evolving, the options to tackle them are just getting better. By leveraging the right technology and building an effective risk strategy, businesses are able to protect themselves and their customers against different types of fraud.

Fraud detection is the process of identifying fraudsters and fraudulent behavior. There are different tactics businesses can use to differentiate legitimate customers from fraudsters, such as using machine learning, pattern recognition, and data analysis. 

Payment fraud solutions can detect behavioral abnormalities and determine whether customers are genuine or fraudsters. Due to the different types of payment fraud, a 'one-size-fits-all' approach will not work. A better way to detect fraud is to invest in financial technology that takes a nuanced approach that balances risk and conversion decisions to reduce costs and maximize revenue.

Fraud prevention is the process of preventing fraudulent activities from impacting the business, customer, or financial institution. To do this effectively, businesses need to maintain full control and reduce operational workload. This is done by combining risk rules with machine learning and manual reviews.

Supervised machine learning Supervised machine learning involves a combination of risk knowledge and machine learning. Businesses can create risk profiles to help automate part of the risk assessment, saving time and reducing risk management efforts. The bigger the scale of the platform the machine learning model is learning from, the more your business will benefit. These models can learn from multiple channels, payment instruments and regions to build strong shopper understanding and ensure that automated decisioning does the heavy lifting.

Customizable risk rules Different industries and business models face different types of risks. Through customizable risk rules, businesses can create risk profiles tailored to their unique needs and use them to complement the payment evaluation process of machine learning models. This can help optimize underperforming risk profiles or rules, and monitor the impact of changes. .

Manual review Certain types of transactions are at a higher risk of being targeted by fraudsters, these include high-value transactions or transactions in high-risk markets. For an extra layer of fraud protection, businesses can choose to manually review these types of transactions before they’re completed to avoid negative bottom line impact.

The best way to optimize your risk setup is to test and experiment. It is hard to know which risk strategy will best evolve with your business and the market unless you test it. To find out what works for you, you can  backtest the impact before you activate a new rule, or change the settings of an existing rule. You can run the rule on historical data to give you more confidence in the effect of the rule before you turn it on. You can set up different configurations and A/B test them against each other to experiment which methods are the most effective for your business.

To know if your fraud strategy is working, you need to be able to measure success in a way that makes sense for your business - taking into account the latest trends, operational particularities, conversion goals and risk appetite. To do this, you need to:

1. Define success

2. Decide KPIs

3. Measure fraud

4. Benchmark

There are different tactics businesses can use as part of their risk strategy to reduce fraud and differentiate fraudsters from genuine customers.

Delegated authentication

Delegated authentication allows businesses to prevent fraud without compromising on conversion rates. It involves handing over the authentication process to a third party and optimizes authentication experiences, especially for returning shoppers. This allows businesses to offer safe and seamless experiences while increasing conversion rates.

3D Secure

3D Secure 2 (3DS) is a security measure for online payments that allows businesses to prevent payment fraud while providing customers with safe and effortless payment experiences. 

With 3DS, the acquirer, scheme, and issuer interact with each other to exchange information and authenticate transactions. This improves the payment experience for your customers and saves you the costs of fraudulent chargebacks.

3D Secure is mandatory for countries mandated under Payment Services Directive 2 (PSD2). However, businesses anywhere can also use it to protect themselves against fraud.  

Tokenization

Tokenization allows businesses to replace sensitive data with non-sensitive ones. This allows businesses to recognize their customers, enables one-click and zero-click payments, increases security and compliance with regulations, and reduces fraud and chargebacks.

Peak season

Fraud increases during peak season. And it’s important to be ready to protect your customers without losing sales. Here are a few things to consider for peak season:

• Fraud setup and rules

• Conversion optimization

• Monitoring and analysis

Risk threats change based on industry, which means that the solutions to support them will vary.

Hospitality

The hospitality industry is especially vulnerable to cyberattacks, with many hotels finding it challenging to keep up with evolving regulations. To address this, hotels need a financial technology partner to implement secure systems that adhere to regulations throughout the entire payment data lifecycle, across different geographies. 

Employing tokenization can also help safeguard guest information from start to finish, enhancing guest experiences while ensuring compliance.

Digital

Combating fraud with manual rules is a time-consuming and ineffective process for digital businesses within the mobility, gaming, or software industry, putting revenue and customer satisfaction at risk.

By using machine learning (ML), businesses can automate complex decisioning to save time and focus on improving customer experiences rather than maintaining static rules.

Online businesses can also use to protect customers from online payments fraud. Digital wallets like Apple Pay and Google Pay, and major card schemes use network tokens to create effortless and secure online payments experiences.

Retail  

Many retailers have operations and channels across regions. Building risk strategies and collecting insights  in one place will create important synergies but it can be a big challenge. With a unified fraud solution, retailers can respond to fraud with customizable risk rules with speed and ease across all their brands and channels.
