Input

Card Mask

A card number with a four-digit mask, the scheme detected from the leading digits, and a Luhn check before submit.

React + Tailwind, shadcn-compatible: press “Copy for AI” and your Cursor or Claude Code agent installs it with the shadcn CLI.

What you can change

  • the label copy and the starting defaultValue
  • the set of detected card schemes
  • the captions of the expiry and code fields

A link for your AI agent: preview, code and instructions.

FAQ

How do I add Card Mask with Cursor or Claude Code?
Press “Copy for AI” on this page and paste it into your agent's chat. The instruction contains the shadcn CLI install command, the dependencies and what to keep, so the agent installs this exact component instead of recreating a lookalike.
What does Card Mask depend on?
No npm packages beyond React and Tailwind CSS.
What can I change in Card Mask?
Adapt: the label copy and the starting defaultValue; the set of detected card schemes; the captions of the expiry and code fields. Keep as installed: the local --vibeui-input-008-* palette — do not swap it for your theme tokens; storing digits only: the spaces are presentation, not the value; the Luhn check on a full number — it catches a single wrong digit before the request.
Is Card Mask free?
Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.

For developers

npx shadcn@latest add https://vibeui.club/r/pro/input-008.json

This command needs a signed link: sign in and open “Component source” below — it issues a working link valid for 30 minutes. All install options

Technical notes

The component is self-contained: one file, no dependencies, its own palette in local variables --vibeui-input-008-*. A client component: "use client". Only the digits live in state, and the spaces are drawn in by a grouping function — a paste in any format gives one result. The payment scheme is detected by prefix and named in words rather than a logo: logos cannot be distributed in a registry. Luhn is computed only on a full sixteen digits. The expiry and the code stand beside it: a card is not accepted without them.
