Verify ID cards, gym memberships, test results, and almost anything else

Your organization issues more than course certificates. Staff ID cards. Gym memberships. Library cards. Medical test results. Professional licenses. Every one of them needs a way for someone to check it is real.

Edutain Certificate Validator Pro handles all of them, so the same plugin doubles as an ID card verifier, a library card verifier, or a general document verification tool.

Leave the course name field empty, add your own custom fields — ID Card Number, Card Type, Test Name, Test Result, License Expiry — and the plugin becomes whatever verifier you need. Someone can then verify an ID card, membership, or document on the same trusted public page your learners already use. Same simple setup. No extra plugins, no developer required.

Why choose Edutain Certificate Validator?

Manual certificate checking and spreadsheet tracking do not scale, and they give employers no way to confirm anything independently. Edutain Certificate Validator gives your organization a complete WordPress certificate verification system that helps you:

• Prevent fake certificates
• Build trust in the credentials you issue
• Reduce time spent answering verification requests by hand
• Provide instant certificate validation, around the clock
• Manage digital certificates professionally

External services

This plugin connects to Freemius, Inc. for optional account connection, Pro license activation and validation, premium plugin updates, and Pro checkout. It is a third-party service, so using these features means data is sent to Freemius.

The Freemius Checkout script is loaded from https://checkout.freemius.com/js/v1/ on the plugin’s Dashboard, Data Management, Upgrade, and Freemius Account screens, where purchasing controls may appear. As with any remote request, this can send your IP address, browser user-agent, and the referring admin page URL. Opening Checkout also sends the selected product, plan, license quantity, and billing cycle. Any contact, billing, and payment details you enter during Checkout are handled by Freemius and its payment providers.

When an administrator connects a Freemius account, activates or manages a license, checks for premium updates, or opts into data sharing, the bundled Freemius SDK may send: your site URL and title; WordPress, PHP, and SDK versions; site language and multisite context; the plugin version and its active, deactivated, or uninstalled state; the administrator’s name and email address; Freemius account, site, install, product, plan, and license identifiers, including a submitted license key; and, only if you enable that optional permission, a list of installed plugin and theme names and versions.

Freemius permissions are shown to you inside WordPress, and optional diagnostic sharing can be turned off there. Some communication is required to activate and validate a Pro license.

Certificate data is never sent to Freemius. Learner names, email addresses, course names, issue dates, authentication codes, custom fields, and verification analytics stay in your own WordPress database.

Freemius terms of service: https://freemius.com/terms/ Freemius privacy policy: https://freemius.com/privacy/

If you configure a certificate logo using an external image URL instead of the WordPress Media Library, your site downloads that image while generating a PDF, and the image host may receive your server’s IP address and standard request headers. No certificate data is included in that request.

Usage

1. 01Install and activate the plugin.
2. 02Open Certificate Validator > Data Management .
3. 03Download the example CSV, upload your completed file, or add a certificate record manually.
4. 04Open the automatically created Validate Certificate page, or add [edcv_validator] to any page or post.
5. 05Give each learner their authentication code or a direct verification link.

Privacy

Certificate records, including learner names, optional email addresses, and the optional expiry_date value, are stored in a dedicated table in your WordPress database. Pro certificate status and custom fields are stored in a separate metadata table.

Public verification compares a submitted authentication code against your local certificate table. Rate limiting creates a temporary transient keyed by a hashed version of the visitor’s IP address. With Pro analytics active, each verification attempt is stored with the submitted code, result, certificate state, timestamp, and a salted hash of the visitor’s IP address. The analytics retention setting controls scheduled deletion, and can also be set to keep logs indefinitely.

Pro email management sends certificate information to valid recipients through WordPress wp_mail() . Bulk email jobs store temporary job state in the edcv_pro_email_queue option, including a job identifier, record-scan cursor, maximum record ID, recipient progress, status, and timestamps. WP-Cron processes eligible records in batches of 15. Delivery, and any transfer to an email provider, depends on your site’s mail setup.

QR codes and PDFs are generated locally. QR generation uses temporary files that are deleted after use. A PDF logo selected from the Media Library is read from its local attachment file. A manually configured external logo URL is downloaded temporarily during PDF generation and then deleted.

The bundled Freemius SDK provides account, licensing, premium update, and checkout functionality. See the External services section above for what is sent, when, and links to Freemius’s terms and privacy policy.

Plugin data is kept on uninstall unless you enable the relevant deletion settings. Core certificate data and Pro metadata and analytics have separate opt-in deletion controls.
