• The orientation and distance and location you hold your clipper card from the reader makes a big difference to if it will be read successfully or not. The antennas in the readers create a highly uneven field and if you hold the card in an area where the field is weaker, it’ll be harder for it to read it. Check it out:

    It’s been a long, long time since I did any RF engineering so don’t hold me to this 😛

    It wasn’t too long ago that BART insisted they would never do this because it wasn’t cost effective. Shortly thereafter (or it could’ve been the other way around) someone discovered that you could ride anywhere in the BART system on Clipper for less than full fare. I suppose losing thousands of dollars every day made Clipper integration miraculously affordable.

    Unless you’re buying a Fast Pass, the BART Clipper readers are much easier to use than the Muni ones. Wave your card, add your money, wave your card again, done. No buttons to push, no menus to navigate, and a $2 instead of $5 minimum. Even saw a Muni Metro booth minder wave a tourist over to the BART machines instead of getting up and explaining how theirs work.
