Abstract: A near field communications (NFC) device is disclosed that interacts with other NFC devices to exchange information and/or the data. The NFC device can include a plurality of secure elements each configured to store one or more card emulation instances. Each card emulation instance is associated with an application identification (AID) and a priority value. The NFC device can route communications between another NFC device and plurality of secure elements based on each card emulation instance's associated AID and priority value.

Abstract: Aspects of the disclosure provide a virtual memory management method that can reduce memory requirement and improve system performance. The method can include detecting a scenario, matching the detected scenario with a predefined scenario that includes a pre-set mapping relationship of a first module to a dynamic memory address within a first portion of a dynamic memory, and writing the first module from a static memory to the first portion of the dynamic memory at the dynamic memory address. Further, the method can include executing the first module from the dynamic memory. In addition, the method can include storing a second module at a second portion of the dynamic memory independent of the detected scenario.
