Abstract
Systems and methods are disclosed herein to provide radio frequency identification (RFID) communication techniques for RFID devices. For example, in accordance with an embodiment of the present invention, a RFID communication system includes a transmission system that provides a radio frequency signal to an RFID device and a detector circuit that detects a response to the radio frequency signal from the RFID device. A controller determines whether the RFID device is operational based on whether the response was detected by the detector circuit. The RFID communication system may be implemented within a handheld device, a manufacturing test system, or any device requiring RFID communication functionality, such as a printer or an applicator for RFID devices.
