Title:
GAME SYSTEM, CARD, CARD SHOE AND CARD-SHUFFING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/026131
Kind Code:
A1
Abstract:
Deck information representing a deck of cards (100) is encoded by the DNA contained in the DNA ink (DNA-containing coating) with which the markings (101) representing card suit or rank are printed. The cards (100) are guided along rails (19) in a card shoe (3). A DNA sensor (13) is provided on the sliding surface (17) of the card shoe (3). When light from a light source of the DNA sensor (13) is shined on the DNA-containing coating of the marking (101) printed on the card (100), the light reflected from the DNA-containing coating (light of a prescribed frequency) is received by the DNA sensor (13). When the deck information is read from the DNA, the card (100) is verified using said deck information and the results of the verification are output, thereby allowing on-the-spot detection of cheating in card games as well as preventing those who have obtained cards (100) dishonestly from reproducing said cards (100).
