    Abstract: In near field communication between an active initiator (30) and a plurality of passive listen devices (40) the initiator device (30) must obtain a unique identity code from each listen device (40) in range by means of an initialisation process. After establishing an RF field (M) and thereby activating the listen devices the initiator (30) transmits a poll request signal. The poll request signal consists of a sequence of couples. Each couple comprises an identification vector (IVC) and an allocation vector (AVC). Each listen device includes a memory (42) which records control code and an embedded introduction vector (IVL). Each listen device receives the entire poll request signal, and compares each received introduction vector (IVC) with its embedded introduction vector (IVL). When a match is found the listen device calculates a time slot for transmission of its poll response signal based on the allocation vector coupled with the matched introduction vector. The time slot calculated will not overlap with any other time slot so that bit level collisions in the poll response signals will be avoided.

    Abstract translation: 在主动启动器（30）和多个被动监听设备（40）之间的近场通信中，发起者设备（30）必须通过初始化过程从范围内的每个监听设备（40）获得唯一的身份码。 在建立RF场（M）并由此激活监听设备之后，发起者（30）发送轮询请求信号。 轮询请求信号由一对夫妇组成。 每一对包括识别向量（IVC）和分配​​向量（AVC）。 每个监听设备包括记录控制代码和嵌入式引入向量（IVL）的存储器（42）。 每个监听设备接收整个轮询请求信号，并将每个接收到的引入向量（IVC）与其嵌入的引入向量（IVL）进行比较。 当发现匹配时，监听装置基于与匹配的引入向量耦合的分配向量，计算用于发送其轮询响应信号的时隙。 所计算的时隙不会与任何其他时隙重叠，以便避免轮询响应信号中的比特级冲突。

    Abstract: A method of simultaneously connecting a first NFC-enabled device in poll mode (52) with a plurality of second NFC-enabled listen mode devices (70, 72, 74), the method comprising: detecting the presence of the plurality of second NFC-enabled listen mode devices (70, 72, 74) and being characterised by: allocating to each of the detected second NFC-enabled listen mode devices (70, 72, 74), a separate logical channel (208) in an NFC controller interface (60) of the first NFC-enabled device (52). In each logical channel (208), a connection is suitably established and maintained and the instantaneous connection status of each of the detected second listen mode devices (70, 72, 74) is suitably monitored and/or recorded. A device-specific RF finite state machine (200) may be used for recording which NFC listen mode devices (70, 72, 74) are connected to the NFC interface (60) using which RF protocols (204). Likewise, a device-specific NCI finite state machine (206) is suitably used for recording which NFC listen mode devices (70, 72, 74) are allocated to which dynamic channels (208) of the NCI (60).
