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.

CVV Format Validation Test Cases: A Comprehensive Guide
Understanding CVV Format Validation
When it comes to online transactions, CVV (Card Verification Value) plays a crucial role in ensuring the security of credit card transactions. This guide provides a comprehensive overview of CVV format validation test cases to help you understand how to validate CVVs effectively.
What is CVV?
CVV is a three or four-digit number printed on the back of your credit card. It is used by merchants to verify the authenticity of the card during online transactions.
CVV Format Validation Test Cases
- Length Check: Verify that the CVV is exactly three or four digits long.
- Digit Check: Ensure that all digits in the CVV are numeric.
- Format Check: Confirm that the CVV is in the correct format (all digits).
- Card Type Check: Validate the CVV based on the card type (Visa, MasterCard, etc.).
Why is CVV Validation Important?
Validating the CVV helps prevent fraudulent transactions by ensuring that the cardholder possesses the physical card. It adds an extra layer of security to online purchases.
