As long as that customer's card is re-photographed again prior to any subsequent photos of the subject, Snapizzi will assign them all to the same gallery for that customer. There is no limit to the number of times a customer can use the same code. They can always use a new card for other photo sets, but the result is they would have a gallery created for the number of cards they used during the event. They would enter each code to find each photo set.
