Sony’s Felica technology is behind many of the most popular contactless NFC smart cards. Already the de facto standard in Japan for commuter travel payments, Felica is being used at the point of sale, railway and air ticketing, as well as for University ID cards – to name a few. It was recently announced that bitcoin has been successfully integrated with Felica technology. Plans have been announced for each contactless smart card to include a bitcoin wallet that holds a private key on the card.
