No api for updating and retrieving the list cards

[renielsalvador]

There is an option for adding cards but, none for updating and retrieving vaulted cards.

I think that generically, in Omnipay, there is no method to retrieve card data -- doing so would probably break PCI requirements. Similarly there is no generic method to update card data -- normally this is done via a card delete / card add. The majority of gateways that support stored card data do not support updating or retrieving that card data.
