摘要

A radio frequency identification (RFID) reader for, and method of, reading an RFID tag to obtain data, includes an RFID module supported by a housing and including an antenna for propagating an electromagnetic field over a field of view, as well as an illuminator supported by the housing for visibly illuminating the field of view to enable an operator to see the illuminated field of view and whether the RFID tag is within the illuminated field of view.

主权项

1. A radio frequency identification (RFID) reader for reading an RFID tag to obtain data, comprising:
a housing; an RFID module supported by the housing and including an antenna for propagating an electromagnetic field over a field of view; and an illuminator supported by the housing for visibly illuminating substantially all of the field of view over which the electromagnetic field propagates to enable an operator to see the illuminated field of view and whether the RFID tag is within the illuminated field of view, wherein the illuminator is configured to provide visible light over a solid, conical angle substantially matching a solid, conical angle of the field of view of the RFID module.
