摘要：
Systems and methods for determining a binary status of a device are provided. A method for detecting an operating status of a device using a radio frequency identification (RFID) tag is provided. The method includes coupling a first portion of the RFID tag to a first portion of the device and coupling a second portion of the RFID tag to a second portion of the device, wherein the first portion of the device is moveable with respect to the second portion of the device, changing a position of the first portion of the device with respect to a position of the second portion of the device, detecting the change in position of the first device portion based on the movement of the first RFID tag portion, wherein the movement causes a change in a status of an RFID signal emitted by the RFID tag, and determining the status of the device based on the change in the RFID signal status.
