Abstract
Systems and methods are disclosed herein to provide RFID communication and testing techniques. For example, in accordance with an embodiment of the present invention, an RFID system includes a radio frequency source adapted to provide radio frequency energy to an RFID device, a short-range coupler adapted to couple with the RFID device, at least one diode coupled to the short-range coupler, and an interface. The interface is coupled to the diodes and adapted to provide via the short-range coupler and the diodes modulation of the radio frequency energy to the RFID device and detection of a signal provided by the RFID device.
