When completed, the NFC Forum’s Host Controller Interface will be a logical interface, allowing an NFC front end to communicate directly with an application processor and multiple secure elements in various electronic devices such as cell phones, PDAs and PC peripherals, enabling faster integration of NFC functionality. The Forum’s HCI will cover all NFC operational modes, including reader/writer, peer-to-peer and card emulation. The HCI may be implemented over relevant physical interfaces, including Serial Peripheral Interface Bus (SPI), Inter-Integrated Circuit (I2C), Universal Asynchronous Receiver/Transmitter (UART), Universal Serial Bus (USB) and others. The interface between the NFC controller and the Universal Integrated Circuit Card (UICC) or SIM card is being specified by the European Telecommunications Standards Institute (ETSI) and is outside the scope of the Forum’s HCI specification work. jkatzman@virtualmgmt.com www.nfc-forum.org
