A new card to attach to the customer. The card can either be a token, like the ones returned by our Stripe.js, or a associative array containing a user's credit card details, with the options described below. You must provide a card if the customer does not already have a valid card attached, and you are subscribing the customer for a plan that is not free. Although not all information is required, the extra info helps prevent fraud.
