Event management includes enrolling prospective participants by associating each participant with a profile. The profile includes the participant's attributes which are vetted automatically or by social networking means. A token is assigned to each profile which enables access to the profiles. An event is created and associated with event access control rules which correspond to various attributes. Access to the event involves scanning the token, accessing a participant's profile and testing attributes in the profile relative to the access control rules. The token can be re-used at different events having different access control rules.
