Saving cards token for Stripe

Hi there,

We sell a product that the final price would be calculated on delivery, I want to
authorize payments and capture the final payment amount later. Also I want to be able to capture a less or greater amount than what is authorize.
I talk with stripe support and they referral me to this page: https://stripe.com/docs/saving-cards

Does your plugin support this API ?
Does the plugin save the cart info on my server or tokenized card information ?

Thank you for your answer.
