RFID tag filtering and monitoring
First Claim
1. A method for initiating actions in response to identifiers obtained from RFID tags, the method comprising:
- (a) providing at least one parameter from a database to at least one RFID reader, wherein the at least one parameter is represented by a range and wherein said at least one parameter is a priority code;
(b) obtaining, with said at least one RFID reader, at least one identifier from at least one RFID tag;
(c) comparing said at least one parameter to said at least one identifier;
(d) determining, based at least partially on said comparing, whether said at least one identifier corresponds to at least one item of interest; and
(e) initiating at least one action, based at least partially on the time of said obtaining, and at least partially in response to a determination in step (d) that said at least one identifier corresponds to said at least one item of interest.

Abstract
A Radio Frequency Identification (RFID) system that tracks tags in real-time based on EPC codes and on other priority codes written into transponder memory fields of the tags. As an example, a priority code may be written into a memory of an RFID transponder identifying a high-value item or a small high-value item that is likely to be stolen. Based on the use of this priority code, those items can be preferentially tracked as opposed to items of low value or size such that they are unlikely to be stolen. Such use of priority codes and local filtering alleviates the need to go back to large centralized databases associating unique numbers with other parameters and potentially the history of the item.

11. An article of manufacture for performing a method for initiating actions in response to identifiers obtained from RFID tags, the article of manufacture comprising a computer-readable medium holding computer-executable instructions for performing a method comprising:
-
(a) providing at least one parameter from a database to at least one RFID reader, wherein the at least one parameter is represented by a range; (b) obtaining, with said at least one RFID reader, at least one identifier from at least one RFID tag; (c) comparing said at least one parameter to said at least one identifier; (d) determining, based at least partially on said comparing, whether said at least one identifier corresponds to at least one item of interest; and (e) initiating at least one action, at least partially in response to a determination in step (d) that said at least one identifier corresponds to said at least one item of interest, wherein the initiating of step (e) is based at least partially on the location of said at least one RFID reader. - View Dependent Claims (12, 13)

14. A system for initiating actions in response to identifiers obtained from RFID tags, comprising:
-
(a) a database for providing at least one parameter and initiating at least one action based at least partially on a determination that at least one identifier corresponds to at least one item of interest, wherein the at least one parameter is represented by a range; and (b) at least one RFID reader for obtaining said at least one identifier from at least one RFID tag and determining whether said at least one identifier corresponds to said at least one item of interest, wherein said determining is based at least partially on comparing said at least one parameter to said at least one identifier and wherein the initiating of at least one action is based at least partially on the location of the at least one RFID reader. - View Dependent Claims (15, 16)
