Abstract:
Aspects of a method and system for identifying a radio frequency identification (RFID) tag location using a switchable coil are presented. Aspects of the systems may include one or more processors that enable selection of an inductor coil from a plurality of inductor coils. The selection of the inductor coil may be based on a change in an electromagnetic field, with respect to an initial electromagnetic field, as detected by the selected inductor coil. The processors may enable transmission of a signal, having a transmitter frequency in the UHF frequency band, via the selected inductor coil.
