An apparatus and method for cashless gaming wherein a player can access credits via a pin activated keypad located on the gaming machine. A switch control circuit receives a shift signal which changes to a random value, performs an operation on the bit number and a value indicated by the shift signal to generate a next bit number, and outputs the generated bit number as the selection signal. QoS setting means sets QoS which the ATM network ought to guarantee, based on the statistical information, and QoS guarantee determining means determines based on the routing information whether or not the set QoS can be guaranteed. The first conductive material layer coats an inside surface of a cup-shaped opening formed in an insulating layer. The frame, unicastmulticast, and frame position flags are then sent to a frame forwarding processor. These features also allow exceptional miniaturization of magnetically active parts called a Cerfite.
