RFID based monitoring system and method
First Claim
Patent Images
1. A system for monitoring an item, comprising:
- a marker tag allocated to an item, the marker tag being a Radio Frequency Identification (RFID) tag including;
a tag module including tag information having a unique identification (ID) and a first antenna operable by a RFID reader; and
a second antenna for inductively coupling to the first antenna and coupling to a master tag for accessing the marker tag, the master tag being operable in a Radio Frequency (RF) field of the RFID reader;
a connector; and
a wired connection system including;
a first cable, the connector detachably coupling the marker tag to the first cable such that the marker tag is replaceable with another marker tag; and
a coupler for coupling the first cable to the master tag, the second antenna operatively coupling to the master tag via the wired connection system such that the tag module is operated by the RFID reader via the master tag.

16. A system for monitoring an item, comprising:
-
a master tag for accessing a marker tag allocated to an item, the master tag being operable in a Radio Frequency (RF) field of a Radio Frequency Identification (RFID) reader and including a connector, the marker tag being an RFID tag operable by the RFID reader and including a tag module tag information; and a wired connection system including; a first cable, the connector detachably coupling the first cable to the master tag such that the master tag is replaceable with another master tag; and a coupler for coupling the first cable to the marker tag such that the tag module is operated by the RFID reader via the master tag. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A system for monitoring an item, comprising:
-
a first cable allocated to a master tag for accessing, by the master tag, at least one marker tag, the master tag being operable in a Radio Frequency field of a Radio Frequency Identification (RFID) reader; a first connector detachably coupling the first cable to the master tag such that the master tag is replaceable with another master tag; each of at least one second cable allocated to a corresponding one of each of at least one marker tag, each of the at least one marker tag being an RFID tag allocated to an item to be tracked; each of at least one second connector detachably coupling each of the at least one of the second cable to each of the at least one marker tag such that a marker tag is replaceable with another marker tag; and a coupler for coupling the second cable to the first cable such that the marker tag is readable and/or writable via the master tag.
