Tarot cards (tarot decks) are a means used by tarot readers and many psychics. A tarot card deck contains 78 cards. Tarot readers practice understanding each of the tarot cards with meanings. A tarot reader must spend countless time in studies of the symbols and numbers on the tarot cards to perform an accurate tarot reading.
The difference between a tarot reading and a mystic reading is that a tarot reader uses tarot decks and a mystic does not. It is more common to come across a tarot card reading psychic since, in new age predictions, these are considered to be closely related.
