Abstract: A contactless system is described in which multiple execution environments may be coupled to a near field communication (NFC) controller, wherein each execution environment is configured to communicate with remote readers via the NFC controller using an assigned one of a plurality of communication protocols. During a polling session from a proximate reader, responding to a request command using a requested communication protocol and activating one of the plurality of execution environments assigned to the requested communication protocol to use the NFC controller. An arbitration is performed in response to each polling session such that a same combination of communication protocol and execution environment is not activated for adjacent polling sessions.

Abstract translation: 描述了一种非接触式系统，其中多个执行环境可以耦合到近场通信（NFC）控制器，其中每个执行环境被配置为经由NFC控制器使用多个通信协议中的一个通信协议与远程读取器进行通信。 在来自邻近读取器的轮询会话期间，使用所请求的通信协议来响应请求命令，并激活分配给所请求的通信协议的多个执行环境中的一个以使用NFC控制器。 响应于每个轮询会话执行仲裁，使得相同轮询会话不激活通信协议和执行环境的相同组合。
