Not that I am aware of but I don't think I have ever looked in this option. You could call one of the cards you have in mind that is a prepaid card and ask about transfer options. Grocery stores have these prepaid cards if you need a phone number, grab it off of the back of one of those!
Probably not. By definition, a prepaid card is where you put money on the card, then use the card for convenience sake. I doubt the card will let you go into debt above what money you put in.
acording to me there is no prepaid credit or debit card comppany that allows you to transfer your balance . it is very long procesure so they cant allow you.
