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.

Abstract: A device and method for determining redundancies in near field communication tag detection are provided. A device comprising: a sensor configured to receive NFC tag identifiers from at least one near field communication (NFC) tag; and, a processor configured to: compare a first NFC tag identifier to a second NFC tag identifier, both the first NFC tag identifier and the second NFC tag identifier having been received by the sensor within a given time period; when the first NFC tag identifier and the second NFC tag identifier are the same, infer that the first NFC tag identifier and the second NFC tag identifier are associated with a single NFC tag; and when the first NFC tag identifier and the second NFC tag identifier are not the same, infer that the first NFC tag identifier and the second NFC tag identifier are associated with two different NFC tags.

Abstract: A mobile wireless communications device may include a satellite position determining device, and a near-field communication (NFC) device being switchable between a first NFC mode and a second NFC mode, wherein the second NFC mode provides a lower power consumption by the NFC device compared to the first NFC mode. A controller may also be coupled with the satellite position determining device and the NFC device. The controller may be configured to switch the NFC device from the first NFC mode to the second NFC mode based upon a determination of movement of the mobile wireless communications device at the rate faster than a threshold rate.

Abstract: A transaction processing system includes an authorization server and an authorization server. A transaction terminal includes a first near field communication (NFC) device and is configured to perform a transaction based upon the authorization data. A mobile wireless communications device includes a second NFC device, at least one movement sensor, and a processor. The processor is configured to send a transaction request via the second NFC device to the first NFC device of the transaction terminal, and send detected data representing a pattern of movement detected by the at least one movement sensor to the authorization server. The authorization server is configured to generate authorization data based upon the detected data. The transaction terminal is configured to perform the transaction based upon the transaction request and the authorization data.
