San Diego Transit Agency to Target Infrequent Riders with Open-Loop Payments–at Least at First

The San Diego Metropolitan Transit System, or MTS, and a smaller affiliated transit agency are planning to introduce open-loop payments in April–deep in the heart of car-centric Southern California.
The open-loop rollout is part of an account-based fare system, which MTS and its main vendor, Germany-based INIT, began rolling out a little less than five years ago.
