Activate the plugin through the ‘Plugins’ menu in WordPress.
Navigate to the “Graded Cards” menu in your admin dashboard to start adding cards.

Frequently Asked Questions
Yes! While designed with sports cards and trading cards in mind, you can use this for any collectible that has a certificate number and a grade, such as Pokémon cards, Magic: The Gathering, Funko Pops, etc.
No. The plugin is designed to be very lightweight. The admin table is paginated to handle large collections without performance issues, and the frontend queries are simple and efficient.
Important: Deleting the plugin via the WordPress admin dashboard will permanently remove the custom database table and all of your card data. This action cannot be undone. If you want to keep your card data in the database, you should deactivate the plugin instead of deleting it.
