These decks allow the user to know the value and suit of the card simply by looking at the back of the cards in a specific spot.
Generally, there are two types of marked decks: Coded and readers. The difference of which lies on how the markings are indicated.
Coded Marked Decks: A system that uses specific markings or patterns on a uniform spot throughout the deck - such as a clock system to determine value.
Reader Marked Decks: A system of which explicitly says the value of the card giving a much faster response time for the performer.
Marked decks, when used right, can be an incredibly powerful tool for magicians.
