The generator creates card-number bodies by brand prefix and computes a valid check digit using the Luhn algorithm. The output is suitable for automated tests and form validation scenarios.
Formula
body = brand_prefix + random_digits
check_digit = luhn(body)
card_number = body + check_digitGenerated values are structurally valid for checksum testing, not real financial instruments.
Example
Example: for Visa, the generator starts with prefix 4 and computes a valid Luhn check digit for a 16-digit output.
FAQ
Are generated cards real?
No. They are random test values intended for non-production use.
Why does checksum matter?
Many systems reject invalid card numbers at input time, so checksum-valid samples are useful in QA.
Can I export in bulk?
Yes, use TXT or CSV export from the generator block.
