<p>METHOD AND DEVICE FOR RECOGNIZING A GRAPHIC ELEMENT PRINTED ON A PLAY SLIP A method for recognizing a graphic element of technical function which is printed on a play slip (10) is based on a comparison of images. The content of an area (30) of the slip in which the graphic element is printed, is compared to reference images. The method is compatible with any mode for printing the graphic element on the slip: alphanumeric codes, barcodes, logos, pictures which vary according to the game, etc., but only uses one recognition algorithm. The graphic element which is recognized may be any graphic element of technical function, including a graphic element of useful data, in particular a game code (3) or a game symbol, or a reference graphic element for determining a position of the slip.
