As a follow up to my recent post about weird cc verifications, Stripe returns a token when I pass a card with a valid number but invalid CVC & zip code. I checked "require CVC & zip code authentication" in the account settings in the dashboard.<p>I will receive an error from Stripe in my iOS app if I pass an invalid card number but a token if I have a valid card + valid CVC.<p>When I charge the card, Stripe errors on the server.<p>How do I authenticate the card immediately, without charging it? (This is critical to the business logic)<p>[1]SO post http://stackoverflow.com/questions/19301798/stripe-card-authentication-passed-from-iphone-failed-on-server
