1. A method of determining a storage location that is currently being processed by a radio-frequency identification (RFID) device, comprising:
- interrogating a plurality of RFID tags associated with a plurality of items with the RFID device;
receiving data with the RFID device from the interrogated plurality of RFID tags, wherein receiving the data comprises reading data specifying storage locations wherein the data is encoded directly within the RFID tags associated with each of the plurality of items; and
heuristically processing the received data with the RFID device to determine a storage location associated with the plurality of items, wherein heuristically processing the received data comprises determining the storage location upon reading a certain number of the plurality of RFID tags indexed to the storage location.

8. A hand-held radio-frequency identification (RFID) device comprising:
-
a reader that interrogates a plurality of RFID tags associated with a plurality of items, wherein the reader receives data specifying storage locations from the interrogated plurality of RFID tags in response to the interrogation, wherein the data is encoded directly within the RFID tags associated with each of the plurality of items; and a processor configured to heuristically process the received data to determine a storage location associated with the plurality of items, wherein the processor is configured to heuristically determine the storage location upon receiving data from a certain number of the plurality of RFID tags indexed to the storage location. - View Dependent Claims (9, 10)
