Efficient near field communication (NFC) tag detection and related methods
First Claim
Patent Images
1. A method of communication between a mobile wireless communications device and near field communication (NFC) devices, comprising:
- polling for NFC devices at a default rate;
detecting a first NFC device in response to the polling at the default rate;
when the first NFC device has been previously detected a first threshold number of times within a first threshold duration, polling for NFC devices at a reduced polling rate;
when the first NFC device is re-detected a second threshold number of times within a second threshold duration in response to polling at the reducing polling rate, polling for NFC devices at a further reduced default rate;
when a second NFC device is detected in response to polling at the reducing polling rate, resuming polling for NFC devices at the default rate after interacting with the NFC device.

Abstract
The present disclosure relates to efficient near field communication (NFC) tag detection and related methods. In accordance with one example, there is provided a method of communication between a mobile wireless communications device and near field communication (NFC) tags, comprising: polling for NFC devices at a default rate; detecting an NFC tag in response to the polling at the default rate; when the detected NFC tag was previously detected a first threshold number of times within a first threshold duration, polling for NFC devices at a reduced polling rate.
