Osaifu-Keitai

Osaifu-Keitai (おサイフケータイ, Osaifu-Kētai?), literally meaning "Wallet Mobile", is a trademark of NTT DoCoMo, which developed the system. It refers to mobile phones that integrate Sony's Mobile FeliCa ICs, as well as to services provided by applications on these phones.

Although it was developed by NTT DoCoMo, the system is also supported by other mobile phone operators, making it the de facto standard mobile payment system in Japan. Osaifu-Keitai services include electronic money, identity card, loyalty card, fare collection of public transits (including railways, buses, and airplanes), or credit card.
