Abstract
A learning device using RFID tags is provided. The learning device includes a platform and at least one RFID tag unit. The tag unit includes at least one RFID tag with an identification code and a magnet at the inner space of the RFID tag unit. When the RFID tag unit is placed at an interrogation zone of the platform, the magnet actuates the magnet-induced switch to turn on and drives the power supply device to provide power. The signal S1 from the RFID tag is transmitted though the RFID reader for decoding and the processing unit for processing. The signal is sent to an audio/video output device for displaying and broadcasting. A plurality of platforms are formed a platform array, each of the platform including at least one receiver and at least one transmitter correspondent to the receiver, the transmitter transmitting a signal which represents the position of the transmitter, while the receiver receiving signals from the transmitter to recognize the relative positions of the platforms.
