Abstract
A portable radio-frequency identifier (RFID) reading terminal can comprise a microprocessor, a memory, an RFID reading device, and a display. The portable RFID reading terminal can be configured to display a scan trace provided by a line comprising a plurality of time varying points. Each point can be defined by a projection of a radio frequency (RF) signal coverage shape of the RFID reading device onto a chosen plane at a given moment in time.

20. An radio-frequency identifier (RFID) reader comprising:
-
a radio frequency (RF) antenna that outputs an RF signal; wherein a scan trace is displayed in response to the outputting the RF signal, wherein the scan trace comprises a line or a plurality of points recorded over a period of time that thereby indicates a path of scanning by the RFID antenna over the period of time in a spatial area.
