NFC routing method
First Claim
1. A device, comprising:
- one or more memories; and
processing circuitry, which, in operation;
responds to a first near field communication (NFC) message from an external NFC device by identifying a first processing device of a plurality of processing devices and processing the first NFC message based on the first identified processing device of the plurality of processing devices;
determines, based on bits of a second NFC message received from the external NFC device, whether the second NFC message was directed to the first identified processing device; and
when it is determined that the second NFC message was not directed to the first identified first processing device of the plurality of processing devices, responds to a third NFC message by identifying a second processing device of the plurality of processing devices and processing the third NFC message received from the external NFC device based on the second identified processing device, wherein the processing circuitry, in operation, responds to the first NFC message received from the external NFC device by applying a first processing rule, and, when it is determined that the second NEC message received from the external NFC device was not directed to the first identified processing device, responds to the third NFC message received from the external NFC device without applying the first processing rule.

Abstract
A near field communication (NFC) router of a mobile device receives a first message from an external NFC device and, in accordance with a first active rule, processes the first message as being targeted to a first host processing device of the mobile device. When the NFC router receives a second message from the external NFC device and detects a bit pattern in the second message indicating that the first host processing device is not an intended target of the second message, the NFC router activates a second rule. When the NFC router receives a further first message from the external NFC device, the NFC router processes the further first message as being targeted to a target host processing device in accordance with the second active rule.
