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 Input Validation Test Cases Guide
Understanding CVV Input Validation
When it comes to online transactions, ensuring the security of sensitive information is paramount. One such piece of information is the CVV (Card Verification Value), a three or four-digit number on the back of credit cards. This guide outlines the essential CVV input validation test cases to maintain a secure transaction environment.
1. Format Validation
The first test case is to validate the format of the CVV. It should only accept three or four digits. Any input that doesn't match this format should be rejected.

2. Length Validation
While the format test ensures the correct number of digits, the length validation checks that the CVV is exactly three or four digits long. This is important to prevent any manipulation of the input.
3. Numeric Validation
CVVs are numeric by nature. This test case ensures that the CVV consists only of digits and does not contain any alphabetic characters or special symbols.
4. Range Validation
Every CVV has a valid range of numbers. This test ensures that the CVV falls within this range, preventing the use of invalid CVVs.
5. Duplicate Detection
It's crucial to detect and prevent the use of duplicate CVVs. This test case identifies any repeated CVVs and flags them for review.
Conclusion
Implementing these CVV input validation test cases is essential for any online platform handling credit card transactions. By ensuring the accuracy and security of CVV inputs, you can significantly reduce the risk of fraudulent activities.
