Single Fare

This type of transaction uses a contactless terminal at points of access to the transit service. The single fare model functions on a "pay as you go" basis, where each journey's fare is individually processed after every trip. Since the fare might not be known at the time of tapping, both tap-in and tap-out data are collected and sent to the transit system.
