Update on Clipper readers (as of Jan. 25)

As some Go Pass users may be aware, Clipper readers at some Caltrain stations were not loading the Go Pass correctly in early January. This issue was caused by connectivity issues and meant that some Go Pass users were unable to tag their Go Passes. All Caltrain Clipper readers should be working properly now, and Clipper is monitoring readers to make sure they stay up-to-date. 

If you were notified by our office that your Go Pass was loaded:

  • Please tag on and tag off for every ride.
  • If you are unable to get your Go Pass to tag on:
    • Please try another Clipper card reader. 
    • Hold your card flat against the Clipper logo on the reader.
    • Some commuters have found that the Clipper card only works when the card is not next to their Stanford ID card or badge, and/or is removed from any plastic ID holder.
  • If you are having trouble with your Go Pass, please contact us at commuteclub@stanford.edu or 650.736.9923.
  • Cash value is NOT required and should NOT be deducted when you use an active Go Pass. If this happens at any time, please call Clipper at (877) 878-8883 for a refund.

Please note that if you have a discounted card (senior, student, disabled), the Go Pass will not work on these cards. Please contact our office for a replacement card. We apologize for the inconvenience.

How to use your 2018 Go Pass

2018 Go Passes are valid Jan. 1 2018, through Dec. 31, 2018. In order to activate the Go Pass, you will need to tag on within 180 days (by the end of June 2018). If you do not tag the pass within this time, please contact our office to reactivate your pass.

How it works:

  • In order to have valid fare, Caltrain requires you to tag on and tag off before and after each ride.
  • When the conductor comes by to check for passes, he or she will scan your Clipper card. 
  • Please review these instructions from Clipper about the tagging process.
