GAME ACCESS DEVICE WITH TIME VARYING SIGNAL

Systems and methods for controlling access to wireless gaming devices and networks are provided. For example, access is controlled through one or more levels of security checks, such as a hard security check instead of or in addition to a soft security check. In a hard security check, the user employs an apparatus such as a card or other physical token that can be used to access the wireless gaming device. Such an apparatus may communicate information that identifies the user to the device or may simply be used to produce a signal without which the device is locked to users. The apparatus may further emit a time varying signal to enhance security.
