Tarot card reading is a form of cartomancy whereby practitioners use tarot cards to purportedly gain insight into the past, present or future. They formulate a question, then draw cards to interpret them for this end. A traditional tarot deck consists of 78 cards, which can be split into two groups, the Major Arcana and Minor Arcana. French-suited playing cards can also be used; as can any card system with suits assigned to identifiable elements.

Tarot is a pack of playing cards, used from at least the mid-15th century in various parts of Europe to play card games such as Tarocchini. From their Italian roots, tarot-playing cards spread to most of Europe, evolving into a family of games that includes German Grosstarok and modern games such as French Tarot and Austrian Königrufen. In the late 18th century French occultists made elaborate, but unsubstantiated, claims about their history and meaning, leading to the emergence of custom decks for use in divination via tarot card reading and cartomancy. Thus, there are two distinct types of tarot packs in circulation: those used for card games and those used for divination. However, some older patterns, such as the Tarot de Marseille, originally intended for playing card games, are occasionally used for cartomancy.
