JIS X 6319-4 is the Japanese Industrial Standard that formalizes Sony's FeliCa contactless smart card communication protocol. Operating at 212 or 424 kbps with Manchester coding, FeliCa achieves sub-100ms transaction times — the fastest of any NFC technology. The standard defines the proprietary polling, anti-collision, and block-based read/write operations used by Suica, PASMO, Octopus, and other major transit systems. It was adopted by the NFC Forum as the basis for Type 3 tags.
