Aggregated Fare Workflow

This type of transaction occurs at a contactless terminal at a point of access to the transit service. The final fare charged is not always available at the time of travel. It is calculated at the end of a travel period (typically 24 hours) based on journeys made during that period.

Diagram that illustrates an aggregated transit transaction.
  1. The cardholder taps the card at a terminal to enter the transit system.
  2. The gate validates the card using offline data authentication (ODA), the card expiration date, and the deny list.
  3. You send an authorization request for a nominal amount.
