Privacy Advocates Raise Concerns Over Clipper Card Data

Listen to the audio:

Bay Area travelers swipe their Clipper Cards 689,000 times per day as they enter a BART station or board a Muni, VTA or AC Transit bus.

But few are aware that the Metropolitan Transportation Commission (MTC) -- the regional agency that administers the card -- keeps information about each Clipper Card transaction for as long as seven years. Someone can demand that information via subpoena or search warrant -- and that's a concern for some privacy advocates.

Where is Clipper Card information about users' travel kept? And what kind of protections does the MTC and operators like AC Transit or BART provide to keep that data secure?

Host Cy Musiker talks with Randy Rentschler, who works on legislation and public affairs for the Metropolitan Transportation Commission.
