Near-field communication (NFC) system with mobile wireless communications devices determining geographic positions of NFC tags and related methods

摘要

A near-field communication (NFC) system may include a plurality of geographically distributed NFC tags, and a tag geo-position database configured to store respective geographic positions of the NFC tags. The NFC system may further include a plurality of mobile wireless communications devices. Each of the mobile wireless communications devices may be configured to communicate with a given NFC tag when in proximity thereto, determine a current geographic position of the mobile wireless communications device, and communicate the determined current geographic position of the mobile wireless communications device to update the tag geo-position database.

主权项

1. A mobile wireless communications device for use in a near-field communication (NFC) system that includes a plurality of geographically distributed NFC devices, each NFC device comprising a first NFC sensor, and a geo-position database configured to store respective geographic positions of said NFC devices, the mobile wireless communications device comprising:
a wireless transceiver, a controller and a second NFC sensor coupled thereto, and configured to
communicate with the first NFC sensor of a given NFC device via the second NFC sensor when in proximity thereto,determine a current geographic position of said mobile wireless communications device, andcommunicate the determined current geographic position of said mobile wireless communications device via the wireless transceiver to update the stored geographic position of the given NFC device in said geo-position database.
