## 説明

Checkify links your WordPress site to your Checkify business account. Once connected,
you can verify visitors using Checkify Passes and embed verification on any page.

**Core features:**

 * QR-based site connection (no API keys to copy)
 * Secure install keypair and short-lived site tokens
 * Verification profiles: human, age 18+, age 21+, age 25+
 * Public PHP API for satellite plugins (`checkify_connector()`)
 * Shortcode: `[checkify_verify profile="is_human"]`
 * Local QR rendering in the browser (bundled QRCode.js)

**Optional satellite plugins:**

 * WooCommerce age gate
 * Contact Form 7 human verification
 * Checkify Page Gate — page/post protection
 * Login and comment protection

### External services

This plugin connects to Checkify services to provide human verification and optional
age verification.

Service used:

 * Checkify API: https://checkify.me
 * Checkify website: https://checkify.me

The plugin connects to Checkify when:

 * A site administrator creates a site connection claim.
 * A site administrator polls the status of a site connection claim.
 * A connected WordPress site creates a verification request.
 * A connected WordPress site checks the status of a verification request.
 * A connected WordPress site confirms a completed verification result.

The plugin may send the following data to Checkify services:

 * The WordPress site domain.
 * A Checkify site identifier.
 * A Checkify installation identifier.
 * A Checkify Pass identifier configured by the site administrator.
 * Verification request identifiers.
 * Verification status tokens.
 * Request timestamps.
 * Cryptographic signatures used to authenticate the WordPress installation.

The plugin does not use an external QR code generation service. QR codes are generated
locally in the visitor’s browser using the bundled QRCode.js library.
