Abstract
In embodiments of the present invention improved capabilities are described for a Radio Frequency ID (RFID) tag that contains multiple Radio Frequency (RF) network nodes that provide enhanced memory capabilities, redundant functionality, and multiple frequency capabilities to the RFID tag using an inter-RF network node communication connection. The inter-RF network node communication may allow the coordination of RFID tag memory and functionality.
