1. A radio-frequency identification (RFID) tag, comprising:
- a plurality of antennas for independently receiving a radio-frequency (RF) signal each;
a plurality of power receiving modules being connected to the plurality of antennas in a one-to-one correspondence and adapted to output an electric power according to the RF signal; and
a wireless communication module being electrically connected to the plurality of power receiving modules for receiving the electric power, so as to determine an identification data that is corresponding to one of the antennas that receives the RF signal and send out the identification data via at least one of the antennas.

Abstract
In a radio-frequency identification (RFID) system capable of detecting RFID tag orientation, a RFID tag thereof comprises a plurality of antennas. When a particular one of the antennas receives an RF signal from a reader of the RFID system, the RFID tag is able to send out an identification data corresponding to that antenna receiving the RF signal, enabling a processor of the RFID system to determine the position and orientation of the RFID tag based on the identification data read by the reader. A puzzle system can be designed by employing the RFID system capable of detecting RFID tag orientation.

7. An RFID tag, comprising:
-
a memory capable of storing a first identification data thereon; a plurality of antennas capable of independently receiving an RF signal each; a plurality of power receiving modules being connected to the plurality of antennas in a one-to-one correspondence and adapted to output electric power based on the RF signal for the RFID tag to operate; a logic circuit being electrically connected to the plurality of power receiving modules and adapted to generate a position data that is corresponding to the antenna receiving the RF signal; a control circuit capable of combining the first identification data with the position data to generate a second identification data; and a modulation circuit capable of modulating the second identification data to generate a modulated signal which is then sent out via at least one of the plurality of antennas. - View Dependent Claims (8, 9)
