• Use Only in Sandbox – Always use generated card numbers in test or sandbox environments. Never attempt real transactions.
• Check Card Types – Select the correct card type (Visa, Mastercard, Amex, etc.) based on your testing requirements.
• Test Edge Cases – Use different card formats, lengths, and scenarios to ensure your system handles all possible inputs.
• Keep Records – Save generated card numbers for automated QA testing and repeated test cases.
• Combine image with CVV & Expiry – Some payment gateways require additional details like CVV and expiration dates, so always follow their sandbox documentation.
