so, i just recently found out that the whole bay area (SF, San jose, Ect.) is going to be using "fare cards". quoting the manufacturer of the card's site Clipper Card Websiteit can take 3-5 days before the value is available to be added to your card. This is because the pass or cash that you add to your card is stored directly on your card, not on a server
Would Rfidiot work in this situation, like how they did in the netherlands?
