Gift Vouchers
Traditional gift vouchers are printed paper gifts available in set values that can be spent in specific stores. Open-loop, semi-open loop, and closed-loop are often terms used when referring to gift vouchers. All gift cards sold via our partners’ websites are closed loop. This means that the gift card can only be spent at a single brand location, for example, an Xbox voucher can only be spent at Xbox etc.

How to Prevent Card Testing on Payment Forms
How to Prevent Card Testing on Payment Forms
Payment forms are prime targets for fraud. One common attack is 'card testing,' where fraudsters test payment cards for validity without making purchases. Here's how to safeguard your forms.
Key Methods to Prevent Card Testing
- Implement CVV Validation: Ensure CVV checks pass to verify the card is present.
- Use 3D Secure Authentication: This adds an extra layer of security through card issuer authentication.
- Monitor and Analyze Transactions: Regularly review transaction data to detect suspicious patterns early.
Understanding CVV Validation
CVV (Card Verification Value) validation is crucial. It helps confirm the card's physical presence and reduces the risk of online fraud.
Card Testing Prevention Best Practices: A Merchant Guide
Enabling 3D Secure Authentication
3D Secure authentication requires cardholders to provide an additional authentication step, such as a one-time password, reducing the risk of unauthorized use.
Monitoring Transactions for Anomalies
Regularly monitoring transactions allows you to identify and respond to suspicious activity promptly, minimizing potential losses.
