Individual cards are the core object within the Clutch platform. You can use a card number to link customer data with, issue balances on it, or attach third party usernames to it. Cards are 1 to 1 synonymous with the concept of a customer record, with the added value of also being able to contain balances in addition to customer demographics, events, and purchase activity.
One card can hold a multitude of balances, but at most one per value type that is configured for the program to which the card’s card set belongs.
A card always has a unique card number, which is what it is identified with within the Clutch Platform. In addition, you can assign a custom card number, for instance your internal system’s customer id, to each card, which can then be used to search matching cards.
