The present disclosure relates to a method for manufacturing a trading card with improved surface characteristics and a trading card manufactured by the method, and provides a method for manufacturing a trading card and a trading card manufactured by the method in which the trading card has a thick UV varnish coating layer, excellent gloss without generating bubbles and improved adhesion of the coating layer by printing and applying UV varnish again on the upper part of the trading card with the UV varnish coating layer and then curing it again.

Provided is a trading card in which a trading card package and content of the trading card package are linked and the content can be specified, and an illegal act can be found. A manufacturing method for a trading card package includes a step of grouping trading cards on which rareness degree information is printed and a step of packaging the grouped trading cards. Trading card IDs are imparted to the trading cards. In the grouping step, the trading card IDs are registered in a database. A package ID is imparted to a package. The package ID is enclosed in the package or provided on the package. The package ID of the package including the trading cards, the trading card IDs, and the rareness degrees included in the package are associated.

Card-handling devices may include an input area sized and shaped to receive cards and an output area for outputting at least some of the cards. A defect detection system may be located along a card path downstream from the input area. The defect detection system may include an emitter positioned and oriented to direct radiation toward a major surface of a card as the card moves along the card path. A detector may be positioned and configured to detect the radiation emitted by the emitter and reflected from the major surface of the card as the card moves along the card path. A controller may be operatively connected to the detector and configured to correlate a signal from the detector with an identification of a degree to which the major surface of the card has deviated from a reference plane.

According to some embodiments, a gaming system includes a first shaped game piece capable of receiving a reversible pigment and a second shaped game piece capable of receiving a reversible pigment. The first shaped game piece and the second shaped game piece comprise a same shape and the reversible pigment comprises a thermochromatic pigment.

The present disclosure relates to a playing card, where a suit and a rank are printed on one surface of a card base sheet, a back pattern is printed on a back surface, an intermediate layer having a black layer or a color layer similar to black is provided on the card base sheet to make transmission of visible rays difficult, and ink containing no carbon is used for printing the suit and the rank. The intermediate layer is configured to prevent transmission of visible rays from the back surface. The suit and the rank printed with the ink containing no carbon are configured to transmit infrared rays. The intermediate layer and the suit and rank printed with the ink containing no carbon are configured such that it is difficult for both the visible rays and the infrared rays to distinguish the suit and the rank from the back surface.
