Mechanical Holdout

Card Switching已報道技術水平：Professional

運作方式

A mechanical holdout is a device worn on the person. It keeps one or more cards out of the game and brings them back when wanted. The hand looks empty. The cards are not in it. This is not hand mucking, which hides cards in the palm. The machine does the hiding.

有案可查

John Nevil Maskelyne describes mechanical holdouts in Sharps and Flats (1894). This entry uses that book. It does not attach a modern case.
