Methods, systems, and apparatuses for a reader
transceiver circuit are described. The reader
transceiver circuit incorporates a frequency generator, such as a
surface acoustic wave (SAW) oscillator. A reader incorporating the reader
transceiver circuit is configured to read a tag at very
close range, including while being in contact with the tag. The transceiver can be coupled to various host devices in a variety of ways, including being located in a RFID reader (e.g., mobile or
fixed position), a computing device, a
barcode reader, etc. The transceiver can be located in an RFID module that is attachable to a host device, can be configured in the host device, or can be configured to communicate with the host device over a distance. The RFID module may include one or more antennas, such as a first antenna configured to receive a
magnetic field component of an electromagnetic wave and a second antenna configured to receive an
electric field component of an electromagnetic wave. The RFID module may include a
detector that is configured to determine if the RFID module is positioned in proximity to an object, such as a RFID tag. The
detector may operate as a trigger for the RFID module, to enable or trigger a function of the RFID module.
