Portable RFID reading terminal with visual indication of scan trace |
摘要 |
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. |
