Two for the price of one here as with Credit Transfer you get a mental effect and a piece of magic together. A borrowed credit card is slipped into a small envelope. Two paperback books are shown and the pages are riffled of one of the books until a spectator calls 'stop'. The credit card in the envelope is dropped into the book to mark the place. The second book is now opened to reveal an envelope is already inside it, and the page it rests on turns out to match the page just selected in the first book. Then the credit card vanishes from the envelope in the first book and arrives inside the envelope in the second book.
