Nagasaki is going all high-tech Sony-style on your ass by actually using Sony's FeliCa technology in mobile phones. Here is a quick refresher: FeliCa is a Sony's contactless IC card technology that is being adapted into various mobile phones. It allows for wireless high speed processing of a slew of information including cash, tickets, credit cards, member IDs, etc. Buses in Nagasaki are going to begin being integrated with FeliCa readers. No need to throw your change at a disgruntled bus driver, just wave your phone in front of the FeliCa reader and you are charged for a ticket, and the ticket information is stored on your phone.
