We have been made aware of a technical issue with the Clipper fare system that is causing Clipper fare readers onboard transit vehicles and stations to reject or fail to activate or accept BayPass. Our partners at AC Transit and the Metropolitan Transportation Comission are currently working with CUBIC, the Clipper vendor, to resolve these issues. AC Transit has notified their operators to honor malfunctioning BayPass Clipper Cards until this issue has been resolved.
If you experience an issue with your BayPass Clipper Card, please submit a report at BayPass Clipper Card Problem Report. This will help our partners to investigate and resolve your issue as soon as possible.
Thank you for your patience while we work through these technical issues.
