How to customise card screen popup

[calistus]

For the pay with new card option, how can we customise the widget that popups where user enters his card detail. Example I'd like to change the button text from "Save" to "Pay" so it doesn't seem like we are saving the user card detail on our Database.

I'm also looking for a way to change this, but I guess we cant customize this.
