The invention comprises a gaming system including at least one gaming machine arranged to accept and print receipts. In one embodiment of a method, a player playing a gaming machine is issued a receipt which represents credit or value belonging to the player, and includes secondary information. The secondary information may comprise promotional award information, such as a matching bet for use in playing another game or a prize, or information unrelated to the games, such as a horoscope. In another embodiment of the invention, a method comprises issuing a first receipt at a first location, such as a parking garage, accepting the first receipt at a gaming machine, issuing a second receipt at the gaming machine and then accepting the second receipt at another location, such as a parking garage exit. In this method, the gaming machine serves as a validation mechanism to a player activity or event.
