I built a free tool to generate realistic-looking credit card details for testing payment forms, checkout flows, and frontend validation.

Key features:

Supports 15+ networks: Visa, Mastercard, Amex, Discover, RuPay, UnionPay, JCB, Maestro, and more

Region-specific formats with a valid Luhn check

Interactive UI with card flip animation

Copy to clipboard or generate a QR code of the card details

No signup, no backend — works offline as a PWA

No tracking or data is stored anywhere

Use case: Testing UIs, building demos, or teaching how payment flows work, without using real card data.

Would appreciate feedback or suggestions from the community!

I'd remove the validador. An idiot will type a real card number and then claim you stole it.

It's client-side code, nothing stored it's for validating fake cards not real
