photopass is a credit-like card you get when you have your picture taken (for me it was with a character, i assume they are at the entrances still too) and the photographer asked me "do you have a photo card?" i say "no" he swipes a card in what looks like a portable credit card reader and hands it to me and I move on. well you know the line is getting long, etc. I remember my mom telling me about it, one card for ALL pictures taken at ALL parks. So - i draw conclusions. Basically, it's a credit card like your KTTW card you keep for your duration at WDW, all theme parks (not sure about DD, water parks, etc) and whenever profesionall photographer takes your pic you give to photographer, he swipes and when you go home you can leisurely view and purchase the pictures taken. it's so awesome to be able to view them at home, that is the ideal for me, at my pace and no pressure. i hate taking time at shutters to look at pics, fall in love and then remember how many other things i have already charged and walk away!! too hard! let me think it over at home!!
