Mistake reveals email addresses of 1,764 Clipper card users

Nearly 1,800 Clipper card users had their email addresses made public to each other due to an office mistake by an administrator of the regional transit fare.

While sending out a mass message, an employee at Cubic Transportation Systems, the private manufacturer of the Clipper card, forgot to address the note in the blind-copy field, resulting in 1,764 card users having their email addresses made public.

The note was intended to remind the Clipper users that their credit cards were set to expire in December and needed to be renewed. While no other personal information was released in the message, the “reply all” listed the personal emails of all people that received the reminder.

Randy Rentschler, spokesman for the Metropolitan Transportation Commission, the public agency that oversees the Clipper card, said the accident was a just a “classic human error.”

“We’re sorry that this happened, we’re apologetic, and we’re going to send out an email to state our apologies,” said Rentschler.

The MTC outsources the day-to-day management of the Clipper card to Cubic, the private manufacturer. While the worker who sent out the email was employed by Cubic, Rentschler said that it was ultimately the MTC’s responsibility.

“We are the managing partners of Clipper and if there is a problem with Clipper, it comes down to us,” said Rentschler.
