Method and systems of registering participants for an event at an event site are disclosed. Identification data specific to a participant encoded on a first token object is read with a mobile computing device. A query is generated from the mobile computing device to a remote event registration system for prior registration data based upon at least a subset of the received identification data. The prior registration data is received on the mobile computing device. A first subset of the prior registration data is transmitted to a local event registration system, and a payment success indicator is received upon successful payment processing. Registrant identification data is generated by the local event registration system in response to recording the first subset of the prior registration data and the payment success indicator.
