How It Works
Learn about the advanced algorithms and AI technology that power our secure test card generation system
Luhn Algorithm Validation
Every generated card number uses the industry-standard Luhn algorithm (modulus 10 algorithm). This mathematical validation ensures all numbers are structurally valid and will pass basic validation checks.
The algorithm calculates a check digit based on the other digits, making it possible to detect simple errors and ensuring compatibility with real payment validation systems.
AI-Powered Test Generation
Our advanced AI system analyzes generated card data and creates comprehensive BDD test scenarios covering common e-commerce payment workflows.
Test scenarios follow the Given-When-Then format, perfect for integration with testing frameworks like Cucumber, SpecFlow, or Behave.

Everything You Need to Know
Get answers to common questions about our credit card testing tools and features
Are the generated credit card numbers real?
No, all generated credit card numbers are completely fake and for testing purposes only. While they pass Luhn algorithm validation, they are not connected to any real accounts or financial institutions. They are safe to use for development and testing.
Can I use these cards for actual purchases?
Absolutely not. These are test card numbers designed specifically for development and testing environments. Attempting to use them for real purchases would fail as they are not linked to any real accounts. Always use legitimate payment methods for actual transactions.
How does the AI test generation work?
Our AI analyzes the generated card data and creates comprehensive BDD test scenarios covering common payment workflows. It generates Given-When-Then scenarios that you can directly use in testing frameworks like Cucumber, SpecFlow, or Behave for automated testing.
What card brands are supported?
We support all major card brands including Visa, MasterCard, American Express, Discover, JCB, and Diners Club. Each generated number follows the specific formatting and validation rules for that particular card brand.
Is this tool free to use?
Yes, our basic credit card generation tools are completely free to use. Advanced features like AI test case generation and bulk export may require a premium account. We believe in supporting the developer community with reliable testing tools.
Do you store any of the generated data?
No, we do not store any generated credit card numbers or personal information. All data generation happens client-side in your browser, ensuring complete privacy and security. Your generated test data never leaves your device.
