Club cards and tickets can be eliminated by providing an application that allows a player's mobile phone to process an image of an optical machine-readable representation of data. At the end of a wagering session on a WGM, the WGM can display a barcode representing a player's winnings, an achievement, game status, etc. The player takes a picture of the barcode with his or her mobile phone. The application on the phone processes the barcode image and automatically updates an account of the player in accordance with the data represented or carried by the barcode. For instance, the mobile phone sends a request to a wagering account server to electronically deposit the winnings, as represented by the barcode, in a wagering account associated with the player's club profile.
