Abstract

A radio frequency identification (RFID) system comprises an RFID tag and an RFID reader that communicates with the tag and a processor. A dynamic electronic product code (EPC) is associated with the reader. The dynamic EPC includes at least one portion that is variable.

Claims

1. A radio frequency identification (RFID) system comprising:

an RFID tag; and

an RFID reader that communicates with the tag and a processor;

wherein a dynamic electronic product code (EPC) is associated with the reader, the dynamic EPC including at least one portion that is variable.

2. The system of claim 1, wherein the variable portion of the dynamic EPC can dynamically change and represents a detected state of the reader.

3. The system of claim 2, wherein the state includes a status or operating condition of the reader.

4. A radio frequency identification (RFID) reader configured to transmit at least one dynamic electronic product code (EPC) associated with the reader, the at least one dynamic EPC including at least one portion that is variable and which represents at least one detectable condition associated with the reader.

5. The reader of claim 4, wherein the condition includes one of a status and operating condition of the reader.
