San Francisco like Tokyo
"BART became the first transit agency in the country Tuesday to test a system-wide cell phone payment program that allows riders to pass through the gates with a wave of their handset. The $200,000 pilot project, which will be tested by about 230 riders for the next four months, utilizes a wireless chip that lets people pay by passing their phone over a wireless reader. BART has been using the contact-free technology in its EZ Rider pilot program, which allows riders to pay at the turnstiles by waving a plastic card that has a wireless chip."
