I just purchased this great wallet. On the DVD, Nardi and Spellman do a routine called "Cash Cabaret." However, as part of the explanation of the DVD, they do not go into detail about how the prediction card ends up in the person's pocket. In the performance of this trick there doesn't seem to be any going back into the wallet or nail writing that I can see.

Does anybody have any information about how to do this aspect of the trick? Feel free to PM me if your explanation would give too much away. Thanks in advance for your help
