TAGR 2.08/30/2023 ![]() ![]() Each Profile has specific Configuration Parameters and covers a particular use case. These Activities can be used as defined in this specification or can be modified to define other ways of setting up the communication protocol, covering the same or different use cases. It describes the building blocks, called Activities, for setting up the communication protocol. The specification explains how the NFC Digital Protocol Specification can be used to set up the communication protocol with another NFC device or NFC Forum tag. It includes bit level coding, bit rates, frame formats, protocols, and command sets, which are used by NFC-enabled devices to exchange data and bind to the LLCP protocol. The specification covers the digital interface and the half-duplex transmission protocol of the NFC-enabled device in its four roles as Initiator, Target, Reader/Writer and Card Emulator. The specification defines the common feature set that can be used consistently and without further modification for major NFC applications in areas such as financial services and public transport. ![]() ![]() It harmonizes the integrated technologies, specifies implementation options and limits the interpretation of the standards in essence, showing developers how to use NFC, ISO/IEC 14443 and JIS X6319-4 standards together to ensure global interoperability between different NFC devices, and between NFC devices and existing contactless infrastructure. This specification addresses the digital protocol for NFC-enabled device communication, providing an implementation specification on top of the ISO/IEC 18092 and ISO/IEC 14443 standards. NFC Digital Protocol Technical Specification The NFC LLCP thus delivers a solid foundation for peer-to-peer applications, enhancing the basic functionality offered by ISO/IEC 18092, but without impacting the interoperability of legacy NFC applications or chipsets. LLCP is a compact protocol, based on the industry standard IEEE 802.2, designed to support either small applications with limited data transport requirements, such as minor file transfers, or network protocols, such as OBEX and TCP/IP, which in turn provide a more robust service environment for applications. The connection-oriented service adds in-order, reliable delivery, flow-control, and session-based service layer multiplexing. The connectionless service offers minimal setup with no reliability or flow-control guarantees (deferring these issues to applications and to the reliability guarantees offered by ISO/IEC 18092 and ISO/IEC 14443 MAC layers). The specification defines two service types, connectionless and connection-oriented, organized into three link service classes: connectionless service only connection-oriented service only and both connectionless and connection-oriented service. NFC Logical Link Control Protocol (LLCP) Technical SpecificationÄefines an OSI layer-2 protocol to support peer-to-peer communication between two NFC-enabled devices, which is essential for any NFC applications that involve bi-directional communications.
