1. An identification device for identifying a patient in a medical setting, comprising:

  • a plurality of tags, each of the tags being configured to produce a wireless identification signal in response to an interrogation signal, wherein the identification signal can be used to identify the patient; and

    a support structure designed and configured to locate the plurality of tags proximate the patient, wherein each of the plurality of tags are supported by the support structure;

    wherein;

    the interrogation signal is generated by a standoff reading device having a plurality of read-range powers and configured to change among the plurality of read range power levels based on the standoff reading device determining how many of the plurality of tags the standoff reading device identifies as being linked with one another; and

    each tag includes;

    a tag identifier that is unique to the patient, the tag identifier generating the identification signal in response to the interrogation signal, wherein the tag identifiers on the plurality of tags are identical to one another; and

    an appended linking identifier appended to the tag identifier, the appended linking identifier of each tag differing from the appended linking identifier on each other of the plurality of tags and being selected and configured in conjunction with the standoff reading device to

         1) allow the standoff reading device to link all of the plurality of tags with one another to the exclusion of any other tags within reading range of the standoff reading device and

         2) allow the standoff reading device to determine how many of the plurality of tags the standoff reading device is recognizing during use so that the standoff reading device can determine when to change among the plurality of read-range powers.
