San Diego’s Metropolitan Transit System (MTS) in the US state of California is rolling out an account-based contactless ticketing system that will let passengers pay their public transit fares with a physical or digital transit card and have those fares capped to a maximum of the price of a daily or monthly pass. MTS’s account based Pronto fare payment system will replace its existing Compass transit card and will also be available on services run by the North County Transit District (NCTD) in the northern part of the San Diego region. When you ride, the one-way fare will be deducted from the card you use — physical or virtual on your phone. A rider will never be charged more than a day pass in a given calendar day, regardless of how many trips/taps they make. Likewise, a rider will never be charged more than a month pass regardless of the number of trips/taps in a calendar month. You’ll be able to track their progress toward a day or month pass on your smartphone or your online account. In addition to fare-capping, the new system will enable users to manage and upload funds to their Pronto account in real time.
