Strategy 1: Device and Browser Fingerprinting
What is Device and Browser Fingerprinting?
Device and browser fingerprinting is a method used to identify unique characteristics about a user's device and browser. It helps e-commerce businesses and retailers differentiate between genuine users and fraudsters, and detect potentially fraudulent activities associated with chargebacks.
How does it work?
- Collection of unique device and browser identifiers: Device and browser fingerprinting involves the gathering of a range of data points (e.g., device type, screen resolution, and browser plugins), which provides a unique hash to represent a user's device and browser combination.
- Cross-referencing against known device profiles: The collected information is compared against a database of known device profiles to determine if a device or browser is legitimate or has been associated with fraudulent activities in the past.
Pros & Cons
- Reduces unauthorized use of stolen information: By identifying unique device and browser characteristics, e-commerce businesses can detect transactions made with stolen credentials, and therefore reduce chargebacks related to unauthorized transactions.
- Mitigates account takeover and Card-Not-Present (CNP) fraud risks: Device and browser fingerprinting can help detect irregular account activity, such as multiple failed login attempts on unfamiliar devices, ultimately reducing the risk of account takeovers and CNP fraud.
- May face user privacy concerns: The collection of device and browser data may raise privacy concerns among users, potentially leading to distrust or reluctance to use the platform.
- Not foolproof; sophisticated fraudsters may bypass fingerprinting: Advanced fraudsters may be able to manipulate or simulate legitimate devices and browsers to avoid detection, ultimately bypassing fingerprinting efforts.
E-commerce and retail managers looking to implement device and browser fingerprinting should:
- Employ fingerprinting libraries: Utilize reputable fingerprinting libraries like FingerprintJS or OWASP Amass to collect unique device and browser attributes.
- Integrate with existing risk assessment systems: Incorporate device and browser fingerprinting into your existing fraud prevention and risk assessment systems, ensuring seamless integration of this chargeback prevention strategy.

By understanding and strategically implementing device and browser fingerprinting, e-commerce and retail businesses can identify potential fraudulent transactions, preventing chargebacks and safeguarding their financial health.
Strategy 2: IP Geolocation and Impossible Travel
What is IP Geolocation and Impossible Travel?
IP geolocation and impossible travel refer to fraud prevention techniques that leverage the user's physical location to identify and flag potentially fraudulent transactions. By determining the user's location through geolocation based on their IP address, businesses can assess the risk associated with a transaction based on its originating location.
How does it work?
IP geolocation works by identifying a user's physical location based on their IP address. This is achieved through the use of commercial or open-source IP geolocation databases, which map IP addresses to specific locations. Impossible travel is the concept of flagging transactions that occur within an unrealistic timeframe, like purchasing an item in New York and then in London just minutes later, given the user's location. Businesses can set specific geolocation-based rules to flag and halt transactions occurring from unusual or high-risk locations.
Pros & Cons
- Prevents fraudulent transactions from unexpected locations: By blocking transactions from high-risk locations or flagged IP addresses, businesses can minimize the chance of chargebacks resulting from fraudulent activities.
- Reduces account takeover attempts: By identifying the user's true location, businesses can thwart account takeover attempts, as the perpetrator will likely be in an unexpected location compared to the legitimate user.
- VPN usage may cause false positives: Some legitimate users may use VPNs to mask their true location for privacy reasons, which can lead to false positives and potential loss of business. Businesses must strike a balance between maintaining user privacy and protecting against chargebacks.
- Limited effectiveness against local perpetrators: Geolocation and impossible travel restrictions are less effective against fraudsters who operate within the same geographic area as the legitimate user.
To implement IP geolocation and impossible travel measures, businesses should follow these steps:
Leverage commercial and open-source IP geolocation databases: Integrating IP geolocation databases like MaxMind or IP2Location with the e-commerce platform will help map user's IP addresses to their actual locations. Regularly updating the database is essential for accurate and up-to-date information.
Set business-specific rules for location-based risk analysis: Define rules based on the transaction's originating location to assess the risk associated with each transaction. For example, businesses may choose to flag transactions from countries with high fraud rates or locations significantly different from the shipping address.
Monitor for unusual transaction patterns: Continuously analyze transaction data to identify unusual patterns that may indicate fraudulent activity, such as a sudden spike in transactions from a specific location. This information can be used to refine location-based risk analysis rules and improve overall fraud prevention efforts.
By implementing IP geolocation and impossible travel restrictions as part of a comprehensive fraud prevention strategy, e-commerce and retail businesses can better protect themselves against chargebacks resulting from fraudulent activities.

Strategy 3: Emulator and Virtual Machine Detection
What is Emulator and Virtual Machine Detection?
Emulator and Virtual Machine (VM) Detection is a fraud prevention technique used to identify and block transactions originating from emulated or virtual devices. Cybercriminals often use these devices as a means to mimic genuine users, conduct illicit activities such as card testing, and avoid detection. Identifying these devices and preventing them from accessing your e-commerce platform is essential to reduce chargeback risks and enhance overall security.
How does it work?
Emulator and VM Detection works by analyzing and identifying specific features, such as system behavior patterns and hardware metrics, which indicate that a device is emulated or running on a virtual machine. If a transaction originates from such a device, the system can flag it as potentially fraudulent and prevent it from being processed, thereby stopping fraudulent activities without impacting legitimate users.
Pros & Cons
- Stops fraudsters from using emulated devices to mimic genuine users: By detecting and blocking access to emulated and virtual devices, the risk of account takeover and card testing fraud is significantly diminished.
- Reduces account takeover and card testing fraud: Emulator and VM Detection disrupts the tools and tactics commonly used by fraudsters to exploit stolen credentials, preventing a considerable proportion of fraudulent transactions.
- May raise user privacy issues: Monitoring and analyzing system features for fraud prevention can potentially infringe on user privacy, leading to concerns and potential backlash from customers.
- May cause false positives for legitimate users on virtual devices: Although rare, some legitimate users may use virtual machines for various reasons. In such cases, blocking their transactions may result in lost sales and disgruntled customers.
To effectively implement Emulator and VM Detection, businesses should consider the following measures:
Integrate detection software to analyze system features: Employ detection tools designed to analyze specific behavior patterns and hardware metrics that can reliably identify emulated or virtual devices. Several commercial and open-source solutions are available, tailored to different environments and requirements.
