You're fed up with the listing of the missing trading cards in your collection (or your child's)? Are you tired of writing dozens of numbers on paper that you then lose? So you're lucky, you just found the solution. You can create multiple collections, either with normal numbering or even with letter-initiated numbering. Customise each collection and add photos from the book. Share with your friends the list of missing or repeated cards for easy exchanges. Simpler can not be.
