Title:
TRACKING PLAYING CARDS DURING GAME PLAY USING RFID TAGS
Document Type and Number:
WIPO Patent Application WO/2020/206311
Kind Code:
A3
Abstract:
System having an 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 card into 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.
