Transit View: Fare Policies and Risks

This page describes how the TAs can utilize UniTiAg services. UniTiAg does not take part in the trip validation process and fare calculation. It only provides OTRBs to the TAs. The TA is free to decide whether a particular card tap should lead to the access granting or declining, and what the fare should be.

LPA Account

Some TA policies may require additional data, not included in the OTRB. In such cases, the TA must keep its proprietary Local Patron Accounts (LPA) and propagate them, at least partially, to the wireless validators.

The policy options and related LPA data are presented in the table below.
