Frequently Asked Questions (FAQ)

What is the Luhn algorithm?
The Luhn algorithm (also known as the modulus 10 or mod 10 algorithm) is a simple checksum formula used to validate a variety of identification numbers, such as credit card numbers, IMEI numbers, and Canadian Social Insurance Numbers. It's a basic check to detect accidental errors, not a security feature.
Are the fake credit card numbers real?
No, the numbers generated by the faker are not real and cannot be used for actual transactions. They are mathematically valid according to the Luhn algorithm but are intended solely for testing and development purposes.
Is it safe to use this tool?
Yes, it is safe. All validation and generation happen directly in your browser, and no credit card numbers (real or fake) are stored or transmitted to our servers. This tool is designed for testing and educational purposes only.
