Tarot card in the context of Tarot de Marseilles

A playing card is a piece of specially prepared card stock, heavy paper, thin cardboard, plastic-coated paper, cotton-paper blend, or thin plastic that is marked with distinguishing motifs. Often the front (face) and back of each card has a finish to make handling easier. They are most commonly used for playing card games, and are also used in magic tricks, cardistry, card throwing, and card houses; cards may also be collected. Playing cards are typically palm-sized for convenient handling, and usually are sold together in a set as a deck of cards or pack of cards.

The most common type of playing card in the West is the French-suited, standard 52-card pack, of which the most widespread design is the English pattern, followed by the Belgian-Genoese pattern. However, many countries use other, traditional types of playing card, including those that are German, Italian, Spanish and Swiss-suited. Tarot cards (also known locally as Tarocks or tarocchi) are an old genre of playing card that is still very popular in France, central and Eastern Europe and Italy. Customised Tarot card decks are also used for divination; including tarot card reading and cartomancy. Asia, too, has regional cards such as the Japanese hanafuda, Chinese money-suited cards, or Indian ganjifa. The reverse side of the card is often covered with a pattern that will make it difficult for players to look through the translucent material to read other people's cards or to identify cards by minor scratches or marks on their backs.

In playing cards, a suit is one of the categories into which the cards of a deck are divided. Most often, each card bears one of several pips (symbols) showing to which suit it belongs; the suit may alternatively or additionally be indicated by the color printed on the card. The rank for each card is determined by the number of pips on it, except on face cards. Ranking indicates which cards within a suit are better, higher or more valuable than others, whereas there is no order between the suits unless defined in the rules of a specific card game. In most decks, there is exactly one card of any given rank in any given suit. A deck may include special cards that belong to no suit, often called jokers.

While English-speaking countries traditionally use cards with the French suits of Clubs, Spades, Hearts and Diamonds, many other countries have their own traditional suits. Much of central Europe uses the Germanic suits of Acorns, Leaves, Hearts and Bells; Spain and parts of Italy and South America use the Latin suits of Swords, Batons, Cups and Coins; German Switzerland uses the Swiss suits of Acorns, Shields, yellow Roses and Bells. Asian countries such as China and Japan also have their own traditional suits. Tarot card packs have a set of distinct picture cards alongside the traditional four suits.
