In a gaming establishment, a player feeds a general purpose charge card such as a VISA, MasterCard or AMERICAN EXPRESS card to a reader at a gaming machine or enters on a keyboard or other input device, information relating to the general purpose charge card, and keys in a desired amount of playing credit and optionally, a PIN (personal identification number) for automatic transmission to a remote financial institution (VISA or other charge card facility) either directly or through an intermediate transaction processing facility. Also transmitted are an identification of the gaming machine and the gaming operator. Upon approval of the requested playing credit, the gaming machine is enabled and thereafter a running net (balance) is kept for the player and/or each machine and/or the gaming operator by accounting for win-lose-draws. After the playing session is over, net playing credit information is automatically transmitted to the financial institution either directly or through an intermediate transaction processing facility so that the entire playing sessions can be a single line item on the player's regular statement from that financial institution. Provisions are made to allow a player to use the same playing credit to play on more than one machine at the same time, to quit a machine and quickly move to another and still keep the same running balance, and to move from one gaming establishment to another on the same running balance.
