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. |
