By one approach this can comprise automatically toggling back and forth between at least two different RFID tag interrogation modes. If desired, and by one approach, such a control circuit can facilitate using a first interrogation mode to read RFID tags and then, in response to a first pre-determined condition, automatically switch to using a second interrogation mode that is different from the first interrogation mode. By one approach, this first pre-determined condition can comprise an RFID tag read rate value. By another approach, alone or in combination with the foregoing, this first pre-determined condition can comprise, at least in part, a pre-determined period of time. | 04-12-2012 |
| 20120274449 | Method and Apparatus Pertaining to Radio-Frequency Identification Tags - A presently-powered RFID tag can itself determine its own relative movement with respect to a reader. This RFID tag can responsively alter its read state to thereby permit the RFID tag to respond to a subsequent read inquiry. By one approach the RFID tag assesses its own movement by monitoring the strength of its received power. By another approach, the RFID tag has a power source that becomes electrically charged via radio-frequency energy received by the tag antenna and that power source is configured to become operably discharged at a point in time that corresponds to a typical null-sensing duration of time for a given application setting for that RFID tag. | 11-01-2012 |

| 20140263603 | Method and Apparatus Pertaining to Use of Both Optical and Electronic Product Codes - A control circuit accesses information regarding both scanned optical product codes as correspond to items being purchased in a given transaction as well as read electronic product codes as correspond to items being purchased in that same transaction.

An example of a discrepancy of likely interest includes noting items for which there is a read electronic product code but not a corresponding scanned optical product code and vice versa. | 09-18-2014 |
| 20140266614 | Method and Apparatus Pertaining to Installation of an RFID-Tag Reader System - One or more RFID-tag readers are operably coupled to one or more RFID-tag reader antennas that are installed to primarily read RFID tags in a given hallway. Accordingly, at least a majority of the area within storage spaces that border the given hallway are without sufficient reader energy to power those RFID tags. Accordingly, many, most, or even all of the items that are stored in the storage space will receive insufficient reader energy to power their corresponding RFID tags. | 09-18-2014 |
| 20140266615 | Method and Apparatus Pertaining to the Use of Statistics-Based RFID-Tag Information - A control circuit has access to coverage information that maps the coverage area for each of a plurality of RFID-tag readers to physical locations within a given monitored facility. The control circuit then uses those readers to read, over time, a population of RFID tags and to store historical-read information comprising corresponding RFID-system metrics along with tag-specific information and corresponding timestamps regarding when the reads occurred. The control circuit uses that historical-read information as corresponds to a given period of time and the aforementioned coverage information to determine sub-groups of the population of RFID tags and then uses the historical-read information to calculate at least one aggregated RFID-system metric on a sub-group level basis for at least some of the sub-groups. The control circuit can use the aggregated RFID-system metric to determine the location of a particular RFID tag by comparing that metric to read-based information regarding that RFID tag. | 09-18-2014 |
| 20140266616 | Method and Apparatus Pertaining to Monitoring Item Source Locations - One maintains a first historical record that correlates each of a plurality of items that each have a unique identifier with one of a plurality of locations with a facility. Upon then determining that a given one of those items is leaving the facility (for example, by detecting that the item is literally exiting a building that comprises the facility and/or that the item is being purchased), that item's unique identifier and that first historical record are used to update a second historical record with respect to which locations within the facility are moving which items. By one approach the aforementioned unique identifier can comprise an electronic product code as comprises a part of a corresponding RFID tag. | 09-18-2014 |
| 20140266617 | Method and Apparatus Pertaining to Use of Multiple Sessions with RFID Tags - 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. | 09-18-2014 |
| 20140266618 | Method and Apparatus Pertaining to the Use of Group RFID Tag Information - A plurality of radio-frequency identification (RFID) tags for corresponding items are read as a group to provide corresponding group information. This group information is used to determine whether at least some of the corresponding items are loose inventory. If desired, a confidence rating as corresponds to this determination can be determined and even displayed. These teachings can then provide for assigning a physical location within a given facility to each of at least some of these items based upon that determination. And again, if desired, a corresponding confidence rating can be determined and displayed as appropriate. | 09-18-2014 |
| 20140266632 | Method and Apparatus Pertaining to RFID Tag-Based User Assertions - An apparatus includes a display and one or more user-assertable surfaces. When asserted by a user, such a surface selectively couples a corresponding near-field RFID tag to a far-field component such that information stored by the near-field RFID tag is transmitted via the far-field component. The display, in turn, presents at least some information that the apparatus receives via an RFID transceiver. Depending upon the design this RFID transceiver can be the same as the aforementioned near-field RFID tag or can comprise a different RFID tag (such as but not limited to a far-field RFID tag). By one approach the aforementioned user-assertable surfaces comprise discrete push buttons. When the far-field component comprises a far-field antenna, asserting such a push button can serve to place the corresponding near-field RFID tag into operable proximity to the far-field antenna. | 09-18-2014 |
| 20140320265 | APPARATUS AND METHOD OF DETERMINING A LIKELIHOOD OF TASK COMPLETION FROM INFORMATION RELATING TO THE READING OF RFID TAGS - Methods and apparatuses are provided using RFID devices to assist in determining a likelihood that the performance of a task has been completed.

| 20140320269 | Apparatus and Method Pertaining to Conveying Information Via an RFID Transceiver - An RFID transceiver and RFID-tag reader cooperate to convey information from one to the other and further accommodate the RFID-tag reader transmitting information to the RFID transceiver that causes a modification of information presented via the RFID transceiver. By one approach an RFID-tag reader detects a circumstance that evidences a particular status as pertains to a particular item of such information in a given RFID transceivers. An RFID-tag reader can then serve to modify the information at the corresponding RFID transceiver. By one approach, the aforementioned information comprises a to-do list. The aforementioned modification can comprise modifying at least one to-do item in that to-do list. The aforementioned detection of a circumstance can comprise detecting a physical location of the given RFID transceiver. That location information can be compared to locations that correspond to specific to-do items in the list to identify correlations that evidence completion of specific to-do items. | 10-30-2014 |
