Abstract: These teachings comprise accessing an identifier as corresponds to a given module of RFID-tagged items and then using that identifier to filter the RFID tag readings. By one approach, one can obtain this identifier for the module by reading an optical code as corresponds to the given module of items. By another approach, one can obtain this identifier by reading an RFID tag that specifically correlates to the given module of items. By yet another approach, one can obtain this identifier by receiving the identifier as entered by an end user who is participating in the RFID tag reading process. If desired, this identifier can serve to recall corresponding information that can serve, directly or indirectly, as filter criterion to use when processing the RFID tag responses.

Abstract: A method for purchasing an item using a mobile device is provided. The method includes but is not limited to inputting identification information into the mobile device which identifies the item for purchase and generating an order for the item identified by the identification information. The method also includes but is not limited to displaying on a display of the mobile device an optical machine-readable representation of the order.
