A deck of cards includes eighty four playing cards. Each playing card has a front surface and a back surface. The front surface of all of the playing cards has the same design. The eighty four playing cards include four sets of twenty one playing cards. Each of the four sets corresponds to a branch of military service and each playing card within each of the four sets of twenty one playing cards corresponding to a rank within a respective branch of the military service

An educational card game, designed primarily for children. A designated deck of cards are broken into several sets, with, the respective sets designated on the backs of the cards. The front of the cards has at feast one colored symbol. The cards, and therefore symbols on the cards, can be designated as number, letter, shape, image or other symbol, depending on what the child is to team from that particular deck of cards. The cards are meant to be played as one of a number of games, so that players can learn while having fun. In one embodiment, a player with a deck of cards attempts to match either the color or symbol of a card atop a “play” pile.

An image is formed on a principal surface and a side face of a card. A thermal transfer printing apparatus includes a first feeding unit configured to feed an intermediate transfer medium including a transfer layer that is disposed on one surface of a substrate in such a manner as to be peelable from the substrate, a second feeding unit configured to feed a thermal transfer sheet including a colorant layer disposed on one surface of a base material, a printing unit configured to heat the thermal transfer sheet based on image data and transfer an ink of the colorant layer onto the transfer layer to form an image, and a transfer unit configured to heat the intermediate transfer medium and transfer the transfer layer having the image formed thereon onto a principal surface and a side face of the card.

An accounting card game is disclosed. The game includes a first deck of cards having a positive numerical value and a second deck of cards having a negative numerical value. The decks have an equal number of cards. For each card in the first deck of a positive numerical value, the second deck includes a corresponding card of a negative numerical value having the same numerical magnitude. Players form matches of positive and negative card of the same magnitude, forming positive and negative match piles, and score points based on the values of the positive match piles. The accounting card game is useful for learning accounting and math skills in a fun and exciting manner.

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.
