Marked cards are decks of playing cards with discreet markings designed to aid magicians or card cheats in quickly reading card values and suits at a glance. There are various techniques used for marking cards; some methods may be visible without needing special gadgets while others require advanced technological solutions.
Playing gambling games using marked cards is considered cheating; however, in card magic it opens up possibilities that would otherwise be impossible to achieve.
Detecting a Marked Deck
As a magician, you may have seen that more and more decks of cards are now being produced with built-in marking systems to enable incredible card tricks that would otherwise be impossible with regular decks of cards. While these markings provide additional help with card tricks, if used incorrectly they could also be detected and used to cheat at games; to prevent this happening it’s wise to only buy from reliable vendors and ensure they have an established history.
There are various methods available to you for marking a deck of cards, each offering their own set of advantages and disadvantages. Blocking is a popular technique used to make identification of suit and rank easier; tinting uses color to highlight parts of cards’ backs like heads for Aces or left wings for Kings; this type of marking may be more subtle but still detectable by other players who closely examine the cards.
Swiping, or marking cards using thin strips of paper, is another effective technique. Usually these strips will bear information such as suit and value of each card in addition to identifying who the dealer is; this method works particularly well if multiple people are manipulating one deck of cards simultaneously.
Other methods involve adding marks to the obverse side of a card, which aren’t visible to anyone but those who added them. Casinos will sometimes alter this side in order to prevent collusion between dealers and customers during table games; players might use special daubs or marking pens during games themselves or while using cards belonging to someone else.
One can read marked decks using several methods, including reader systems and coded systems. While simple tinting cannot tell value or suit of cards from a distance, reader systems use more sophisticated methods like NU-CONCEPT’s Luminous Deck that uses luminous formula marking cards so they are visible only to people wearing sunglasses with filters or special contact lenses.
Reader Systems
When it comes to marking cards, some magicians prefer using an obscure coded system reliant on obscure symbols. Though difficult for spectators to decode, this system can be very effective as you’ll have plenty of other considerations while performing such as patter, presentation and technique without worrying about deciphering each card back at the same time.
An easier approach can be achieved using reader systems included with some of the top marked decks on the market. These systems incorporate hidden information about suit and value onto each card face, which only a specialized IR camera can read. Some readers even offer tricks you can perform using their marked deck.
Some readers require special contact lenses or sunglasses, while others can be used with a poker analyzer smartphone. No matter which reader you select, quality should always be considered when purchasing it; look for devices with high-resolution scanning cameras capable of providing clear images of marks.

Coded Systems
Some card-marking cheaters take it one step further by altering the edges of each card to mark its suit and value, known as “shading.” This process can be completed manually with an air brush, templates or using special devices that detect invisible light or infrared, although its results remain invisible to the naked eye.
Marking a deck of cards using ink marks is the simplest and least specialized way to do it, since no special tools are needed for reading them; unlike luminous ink, which requires special glasses or contact lenses for viewing; ink marking is also known as two-way line shade marking.
Examining the texture of cards can also help identify a marked deck. Marked cards might feel different than regular cards or may emit an unusual odor; furthermore, if packed prior to their ink drying they might stick together and make identification impossible.
Pay attention to other players. If someone consistently wins with odd hands, this could be a telltale sign they are using best marked deck of cards.

While standard marked cards cannot be read with mobile phone poker analyzers or external scanners, barcode marked cards can. Whether or not these devices will work for you depends upon how well you understand their nuances and know how to read them correctly.
The Riffle Test
The Riffle Test is one of the easiest and simplest ways to identify whether a deck of playing cards has been marked. This technique involves riffling them and closely inspecting every part of their back for signs of movement – when using block-out, tinting or cut-out work to mark cards it should show movement when being riffled, something even non-expert players can detect easily; luminous or juice methods however are more difficult.
Marking a deck of playing cards can be done in various ways, all designed to help cheats read what card they’re holding. While the early forms of marking were limited to bends and crimps on cards, later cheats began altering back designs using paints, pigments, scratches or any combination thereof. Subtle methods of marking include colouring in or scratching off small sections of cards to reveal lighter or darker spots or altering colours altogether; another advanced way involves the use of luminous markers that only become visible under certain light conditions or when combined with special glasses.
Some cheats don’t need to mark all of the cards in a deck in order to gain an advantage; rather, they may use just marking one rank (usually an Ace) to allow them to see when they have been dealt an advantageous hand – even this simple tactic could give a significant edge against their opponents in Texas Hold’em and other poker games.
As technology has advanced, so has our ability to detect marked decks. A number of companies now provide decks that are immune to the riffle test and compatible with various reading systems – these decks may not be perfect but can still serve as powerful tools when performing magic or mentalism – available with both Bicycle and Beeback designs for maximum effect when blindfolded for added effect.
