RFID communication systems and methods
First Claim
1. A radio frequency identification (RFID) communication system comprising:
- a transmission system for providing a radio frequency signal to an RFID device;
a detector circuit, coupled to the transmission system, adapted to detect a response to the radio frequency signal from the RFID device; and
a controller, coupled to the detector circuit, adapted to determine whether the RFID device is operational based on whether the response was detected by the detector circuit.

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.
