# CustomerCardInstance

> Represents the current load state of a single customer card for a specific customer.

A customer can only have one card instance per config at any point in time. The three concrete implementations — `CustomerCardInstanceLoading`, `CustomerCardInstanceLoaded`, and `CustomerCardInstanceError` — reflect whether the card is being fetched, has loaded successfully, or failed to load.
