Verifying eligibility of players attempting to participate in gaming events is disclosed. Communication objects having RFID tags and closed circuits are worn by players within a verification system. A casino desk, hotel concierge, or other entity can administer the system. These RFID tags are adapted to communicate with associated tracking units attached to gaming machines and other devices via radio waves. Each communication object is adapted to alter its communication pattern responsive to any break of its closed circuit. Communication objects may be bracelets, wristwatches or collars, such that object removal results in the closed circuit breaking, thereby disabling or de-authenticating the device. A communication object may emit a signal which can be tied to one of two or more accounts. One of the two accounts may be charged for a player transaction depending on the transaction nature. A server having a verification program and database may also be used.
