About Luhn Lab
Luhn Lab is an educational sandbox to learn and test Luhn validation. Walk through an interactive “How Luhn Works” tutorial, paste lists to check which numbers pass Luhn, generate synthetic card data from BIN patterns with expiry/CVV, and look up
BIN details. Built for demos, QA, and learning—never for real payment transactions. Includes in‑app privacy notice.
