Abstract

A RFID tag system may be configured as a tag having a first band (e.g., multiple channel-based NBFM frequency band) transceiver to allow field programmability of tag behavior and onboard tag data. The RFID tag system may be configured to collect data from one or more local sensors through the first band link and store data points of interest in tag onboard storage. The RFID tag system may be configured to work in conjunction with a remote interrogating unit, and a handheld device or other local interrogating unit may be additionally or alternatively provided to communicate with such aRFID tag. Data that is stored on the RFID tag may be retrieved or changed, and/or the operation of the tag may be modified.
