No. Although every code is unique, they can be shot in any order. If a customer's card(s) are 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 camera card. They can always use a new card for other photo sets, but the result is that they will have a gallery created for each card used during the event. It is, of course, easier if they just use the same card.
Shooting multiple cards in a keyframe photo will place all photos in that series in each customer's gallery whose card is photographed. We recommend not shooting over 20 cards at a time in one frame.
Ensure that you photograph the codes so that Snapizzi can scan the DataMatrix code properly. We recommend the codes be a minimum of 100x100 pixels in size. Snapizzi has a 100% accuracy rate as long as the coded cards are photographed properly.
Give as much care and attention to photographing the camera card keyframe photo as you do your subjects.
