Recent data pulled from ACI Worldwide’s 2016 Mass Transit Payments Report shows that almost 70 percent of San Francisco’s public transit riders don’t trust that their payment information is secure when they buy tickets.

Two thousand transit riders were polled in nine major cities to gather the results. San Francisco’s rating is tied with Miami for the least trust over its payment security systems.

Other data that came from the poll: 19 percent of San Francisco’s transit riders preferred to use a mobile app to purchase their fares. The City also ranks lowest on the list of riders who prefer to pay with cash, coming in at only 57 percent.
