alt Hacker NewsThat also happens with Clipper Card in the Bay Area. Happened to me a couple of weeks ago on BART. I wonder if all transit cards need to be loaded with money when used on iPhone. I remember having a Clipper Card with autoload and that would work just fine without balance.
You might be right. I like how NYC is set up with just tap to pay with your wallet app without needing to unlock or anything.
