Relationship between NFC and FeliCa

The figure above shows the relationship between the different building blocks of the FeliCa technology and open standards.

The each component of FeliCa technology is described in ISO/IEC communication standards, NFC Form specifications defining the digital interface and half duplex communication protocol, and a Japanese Industrial Standard, JIS X 6319-4, that includes additional message formats and commands.

Open-command based applications not using the FeliCa cryptography such as e-money viewers can be fully developed using information from publicly available specifications.

An excellent feature of NFC is that it has a module structure, composed of wireless communication technologies, mode commands and message formats. It offers very flexible development and at the same time hides the complexity of these technologies in order for application developers to easily enter into the NFC business.

You may know that Android - the smart phone operation system from Google - supports NFC since its 2.3 version. A number of applications using the NFC functionality are available in the Android market. It is remarkable that applications created by everyday developers like e-money viewer are included in the Android market.

The relationship between NFC and FeliCa can be summarized as follows: NFC-F and FeliCa are the same wireless communication technology and FeliCa is a contactless IC card operating system on -top of the open NFC-F standards.
