Abstract
A device configured for tracking spatial placement of one or more HF (High frequency) RFID (Radio-frequency identification) tag objects on a surface is disclosed. The device includes an HF RFID reader, a transmission antenna, and a plurality of reception antennas. The transmission antenna effectively transmits power and data over an area that is defined to be a detection surface. Each one of the plurality of reception antennas is able to effectively receive data from a separate portion of the detection surface, while all of the plurality of reception antennas together are able to effectively receive data from substantially all of the detection surface. In one embodiment, the transmission antenna is constantly transmitting power.
