A method for preventing repeating identification of card symbols comprises the steps: obtaining an environmental image of an identification zone as a reference sample before the game starts; a dealer dealing a poker card into the identification zone with the card symbol identified and continuously obtaining the current image of the identification zone; after the poker card is moved to a card display zone, comparing the current image with the reference sample; if the difference between the current image and the reference sample is smaller than an error allowance value, judging the poker card is fully removed from the identification zone, and proceeding dealing and identification process of next round; if the difference between the current image and the reference sample is greater than an error allowance value, judging the poker card is not fully removed from the identification zone, then the dealer can perform manual process as required.
