I just purchased the newest version for my 4.7.5 store a few weeks ago. I didn't see anything about being able to save a card to charge later. I get lots of customer asking me to add something on and just charge their card, which has been impossible until now. So how do I activate this and use it? I didn't see anything in the instructions, but I might have just missed it. If it is there, give me an idea where to find it please.
