Paying in park with giftcard?

[disneypolybride2008]

Hi, my question is if you use a disney gift card to pay do you have to sign? What about using it at restaurants? If you use the Disney Visa Rewards Redemption card do you have to sign? I am thinking of getting a disney gift card to use instead of using our magic band if i won't have to enter a pin and/or sign.

thanks!
