READING RFID TAGS IN DEFINED SPATIAL LOCATIONS
First Claim
1. A system comprising:
- a processor;
a memory;
an RFID reading device including at least one radio frequency (RF) antenna;
wherein said system is configured to read a first plurality of RFID tags attached to items disposed within a first spatial zone;
wherein said system is further configured to read a second plurality of RFID tags attached to items disposed within a second spatial zone; and
wherein said system is further configured to produce a list of identifiers of RFID tags which belong to said second plurality of RFID tags and do not belong to said first plurality of RFID tags.

Abstract
Devices, methods, and software are disclosed for reading RFID tags located in defined spatial locations. In one illustrative embodiment, a system can comprise a processor, a memory, and an RFID reading device including at least one radio frequency (RF) antenna. The system can be configured to read a first plurality of RFID tags attached to items disposed within a first spatial zone and read a second plurality of RFID tags attached to items disposed within a second spatial zone. The system can be further configured to produce a list of identifiers of RFID tags which belong to the second plurality of RFID tags and do not belong to the first plurality of RFID tags. In some embodiments, the system can be further configured, responsive to successfully decoding decodable indicia attached to an item, to match the item to an RFID tag belonging to the list.
