Benefits of technology
This solution ensures that the operator receives accurate information about the specific tagged object they are handling, reducing confusion and increasing efficiency by minimizing responses from other nearby tags, thus enabling effective use of RFID technology in commercial applications like airline baggage handling.
Problems solved by technology
Specifically, conventional RFID systems lack any means for discriminating in favor of an individual tagged object a human operator is working with at any given moment; instead, conventional RFID systems generally would confuse the operator by providing information regarding all the tagged objects in the vicinity.
Furthermore, if a number of personnel are working close to each other, conventional RFID systems cannot direct information about a tag to the specific individual who is handling the tagged object.
Conventional RFID systems lack any means for detecting which individual suitcase a human operator or baggage handler is about to pick up so as to provide to the operator only the destination or routing information for the suitcase that person currently is handling, to the exclusion of information about other nearby suitcases.

1. Overview
[0015]The invention will be described in the context of an exemplary implementation, depicted in FIG. 1, in which the human operators 10 are baggage handler personnel working in an airport baggage sorting facility, and the tagged objects 12 are airline baggage. However, the invention is equally applicable to any other objects to which RFID tags may be attached.
[0016]In the airport example, a number of baggage handler personnel 10, hereinafter called “operators”, are responsible for loading a large number of suitcases 12 and other baggage pieces into various freight containers 14, where each freight container has been designated to be loaded on a specific aircraft flight. An operator's job is to read the designated flight number and / or destination from a tag 16 attached to each suitcase and then to load the suitcase in the correct freight container.
[0017]Personnel at the airport passenger check-in counter attach an RFID tag 16 to each suitcase 12. Preferably, the RFID tag ...

A method of verifying whether an object to be transported has reached its intended destination. In one aspect, an interrogator transceiver at a first destination interrogates an RFID tag transceiver on the object, and in response the tag transmits its intended destination. The interrogator verifies that the RFID tag transceiver and the object are being routed to the intended destination. Devices and systems associated with the above-referenced methods are also disclosed.
