EXPANDED COMPATIBILITY RFID TAGS
First Claim
1. An integrated device for tracking a container, the device comprising:
- a passive tag reader configured to observe responses to interrogations, the interrogations sent from an external tag reader, and the responses sent from one or more passive devices; and
an active tag, coupled in communication with the passive tag reader, the active tag configured to access information related to the responses.

Abstract
Systems and methods for providing expanded compatibility in identification tags such as RFID (Radio Frequency Identification) devices. Integrated devices can be equipped with various combinations of passive and active tags configured for compatibility with passive and active readers, respectively. Additionally, the integrated devices can be equipped with various combinations of passive and active tag readers for compatibility with passive and active tags, respectively. A first combination comprises an active tag and a passive tag reader for collecting information over a passive channel, and sending the information over an active channel. A second combination comprises an active tag and a passive tag receiver/transceiver for communication over both active and passive channels. A third combination comprises an active tag and an active tag reader for collecting information over an active channel, and sending information over an active channel.
