Reach Pin Pad

Component

About

A PIN entry keypad built for one-handed phone use. A toggle shifts the whole grid to sit under the left or right thumb's natural reach zone instead of centering it, which is where most PIN pads put it and where a thumb has to stretch the most. A wrong code shakes the whole pad and flashes the dots red; a correct one settles the dots to green and reveals an "Unlocked" line.

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Reach Pin Pad to your project and fits it to your theme.

Code

How Reach Pin Pad is used: the demo's code. The component's own source comes with a free account.

Usage.tsx

import * as React from "react";
import { ReachPinPad } from "@/components/ui/reach-pin-pad";
import { Lock } from "lucide-react";

const VALID_CODE = "2468";

export default function ReachPinPadDemo() {
  const [hand, setHand] = React.useState<"left" | "right">("right");

  async function handleComplete(code: string) {
    await new Promise((r) => setTimeout(r, 350));
    return code === VALID_CODE;
  }

  return (
