A system having a radio-frequency-identification (RFID) tag reader and a camera to map playing cards to RFID tag values. Each card is inserted into a sleeve that has an RFID tag. During or after insertion of a card into a sleeve, the camera captures an image of the card and the RFID reader captures an RFID tag value for the sleeve. The identity of the card is then determined from the captured image and mapped to the RFID tag value. This mapping information is generated for each card-sleeve pair in a card deck and utilized to track the movement of the cards during game play. The RFID tag value of each card-sleeve pair in the card deck is captured before and after a player draws a card from the deck. The missing RFID tag values are compared to the mapping information to identify which cards where drawn by the player.

Lenticular products and methods of manufacturing. A lenticular product can include a lenticular sheet having a front surface and a back surface, the front surface including an array of lenticular lenses. Images can be printed on the back surface of the lenticular sheet, and each of the images can be arranged into frames interlaced with other frames corresponding to other images, wherein each of the frames is aligned with a lenticular lense such that light reflected from frames associated with a same image are refracted in a same direction and frames reflected from frames associated with a different image are refracted in a different direction. The lenticular can include a backing layer having a first surface coupled to the back surface of the lenticular sheet and a second surface opposite of the first surface. The backing layer can include instructions and/or images on the second surface representing a sports move.

Internally illuminable playing cards are disclosed. The disclosed playing cards may include a polymeric body, at least one light-emitting diode (LED) at least partially inside of the polymeric body, a battery (or a slot in the polymeric body for receiving a battery) for providing power to the at least one LED, and a switch at least partially inside the polymeric body and operatively connected to the at least one LED to facilitate turning the at least one LED on and off. As can be understood based on this disclosure, the internally illuminable playing cards can be used for flourishing and cardistry techniques, in a manner similar to the way typical paper playing cards are used for such techniques.

A table game system is provided that includes a plurality of association tables, each of which makes it possible to obtain the correlation between codes attached to shuffled playing cards and the ranks thereof, and prevents the correlation between the codes of the shuffled playing cards and the ranks thereof from being known by a person who intends to commit cheating by changing the association table used as appropriate. A card shoe apparatus 2 of the table game system of the present invention includes a barcode reader 100 that reads a barcode 3 attached to a shuffled playing card set 1s, and thereby reads a shuffled card ID that can uniquely identify the shuffled playing card set 1s. The shuffled card ID of the shuffled playing cards to be used is subjected to a process of association to identify one of association table numbers (T1 to T10) or database numbers, and the rank and the suit of a card 1 that are attached to the card 1 are identified based on a code C with an association table (T3). If the code C does not match a code defined in the association table (T3), an error occurs and it is determined that cheating may be committed.

An electronic card game system and method using NFC or RFID electromagnetic communication, including an initiator having a driving coil, a first card having a secondary coil with a capacitor, and a playing piece having a receiving coil. The initiator and the first card may be placed on a playing surface so that at least a portion of the driving coil and at least a portion of the secondary coil overlap. Similarly, the first card and the playing piece may be placed on a playing surface so that at least a portion of the receiving coil and at least a second portion of the secondary coil overlap. These overlapped coils allow a driving signal initiated at the driving coil to be transmitted through the secondary coil and received by the receiving coil.

WAN is a child friendly educational card game that can be used to teach the concepts of trigonometric functions and identities or can be played as a simple card game by anyone over seven years old. The game uses all six basic trigonometric functions and their squares. These trigonometric functions are represented by various shapes and colors on the cards. Mathematical operations are determined by how the cards are placed. The game is played by creating card hands representing functions and operations that equal the number one. These card hands are called WAN hands.
