The SMART eTickets app by Sonoma-Marin Area Rail Transit (SMART) simplifies ticket purchasing and usage for commuters. By registering your email address and securely linking your debit or credit card, you can conveniently buy and utilize one-way or round-trip tickets instantly on your iPhone. The app offers discounted fares for eligible passengers such as Youth, Seniors, and individuals with disabilities, allowing for single or group fare payments.

Users can store multiple tickets on their device for future use, activate tickets before boarding, and manage their payment methods securely within the app. It's essential to activate tickets before boarding, display them to SMART personnel, and ensure your mobile phone is operational with sufficient battery prior to travel.
