FAQ
- Is it safe to enter card numbers here?
- These tools are for development and testing only. All processing happens in your browser — no data is sent to any server. Never enter real production card numbers in any online tool.
- What is the Luhn algorithm?
- The Luhn algorithm is a checksum formula used to validate credit card numbers, IMEI numbers, and other identification numbers. It detects single-digit errors and most transpositions.
- Can I generate test card numbers?
- Yes. The test card generator creates Luhn-valid card numbers for development testing. These are clearly marked as test numbers and cannot be used for real transactions.
