Cartomancy is fortune-telling or divination using a deck of cards. Forms of cartomancy appeared soon after playing cards were first introduced into Europe in the 14th century.
Practitioners of cartomancy are generally known as cartomancers, card readers, or simply readers.
Cartomancy is one of the oldest of the more common forms of fortune-telling. In English-speaking countries the most common form of cartomancy is generally tarot card reading. Tarot cards are almost exclusively used for this purpose in these places.
Cartomancy using standard playing cards was the most popular form of providing fortune-telling card readings in the 18th, 19th and 20th centuries. In English-speaking countries Tarot cards are more commonly used, however a standard deck of Anglo-American bridge/poker playing cards (i.e., 52-card, four-suit set) can also be used; the deck is often augmented with jokers, and even with the blank card found in many packaged decks. In France, the 32-card piquet playing-card deck is most typically used in cartomancy readings, although the 52 card deck can also be used. (A piquet deck can be a 52-card deck with all of the 2s through the 6s removed. This leaves all of the 7s through the 10s, the face cards, and the aces.)
