Method and apparatus pertaining to use of multiple sessions with RFID tags
First Claim
1. A method of interacting with radio-frequency identification (RFID) tags at a facility having a first area and a second area that is at least substantially non-overlapping with the first area, the method comprising:
- using at least a first RFID-tag reader configured to read RFID tags in a first inventory state in the first area using a first session protocol while also contemporaneously using a second session protocol to cause the RFID tags in the first area to switch to the first inventory state with respect to the second session protocol;
using at least a second RFID-tag reader configured to read RFID tags in the first inventory state in the second area using the second session protocol while also contemporaneously using the first session protocol to cause the RFID tags in the second area to switch to the first inventory state with respect to the first session protocol.

Abstract
At a facility having a first area and a second area that is at least substantially non-overlapping with the first area, these teachings provide for using at least a first RFID-tag reader to read RFID tags in a first inventory state in the first area using a first session protocol while also contemporaneously using a second session protocol to cause the RFID-tag reader to cause RFID tags in the first area to switch to that first inventory state. In a similar manner these teachings also provide for using a second RFID-tag reader to read RFID tags in the first inventory state in the second area using the second session protocol while also contemporaneously using the first session protocol to cause RFID tags in the second area to switch to the first inventory state.

6. A method of interacting with radio-frequency identification (RFID) tags at a facility having a first area and a second area that is at least substantially non-overlapping with the first area, the method comprising:
-
using a first plurality of RFID-tag readers that are each configured to read RFID tags in a first inventory state in the first area using a first session protocol while also contemporaneously using a second session protocol to cause the RFID tags in the first area to switch to the first inventory state with respect to the second session protocol; using a second plurality of RFID-tag readers that are each configured to read RFID tags in the first inventory state in the second area using the second session protocol while also contemporaneously using the first session protocol to cause the RFID tags in the second area to switch to the first inventory state with respect to the first session protocol. - View Dependent Claims (7, 8, 9, 10)

-
a facility having a first area and a second area that is at least substantially non-overlapping with the first area; at least a first RFID-tag reader configured to read RFID tags in a first inventory state in the first area using a first session protocol and that is also configured to contemporaneously use a second session protocol to cause the RFID tags in the first area to switch to the first inventory state with respect to the second session protocol; at least a second RFID-tag reader configured to read RFID tags in the first inventory state in the second area using the second session protocol and that is also configured to contemporaneously use the first session protocol to cause the RFID tags in the second area to switch to the first inventory state with respect to the first session protocol. - View Dependent Claims (12, 13, 14, 15)
