Abstract
An apparatus for detecting the information about a guideway-guided vehicle having a masking component, the guideway-guided vehicle configured to follow a path of a guideway, comprising a radio frequency identification (RFID) system, method of making, and use thereof are disclosed. The RFID system comprises a first RFID transponder for transmitting, across the path, first RFID transponder specific information. An RFID reader comprises a first antenna for receiving the first RFID transponder specific information. The first RFID transponder and the first antenna are fixed relative to the path and on opposite sides of the path. The RFID reader is configured to substantially continuously monitor the first transponder specific information. The presence of the masking component of the guideway-guided vehicle between the first RFID transponder and the first antenna masks the substantially continuous monitoring of the first RFID transponder specific information.
