Playing card

A playing card is a typically hand-sized rectangular (in India, round) piece of heavy paper or thin plastic used for playing card games. A complete set of cards is a pack or deck. Playing cards are often used as props in magic tricks, as well as occult practices such as cartomancy, and a number of card games involve (or can be used to support) gambling. As a result, their use sometimes meets with disapproval from some religious groups (such as conservative Christians). They are also a popular collectible (as distinct from the cards made specifically for collectible trading card games). Specialty and novelty decks are commonly produced for collectors, often with political, cultural, or educational themes.
