Multi-secured RFID electronic seal

A multi-secured protection method of a RFID electronic seal comprising the steps of:

• providing a bolt with a male bolt portion, the male bolt portion having at least one electrical connecting point;
• providing a bolt pedestal with a female pedestal portion, the bolt pedestal correspondingly receiving the male bolt portion of the bolt to securely lock with each other, the female pedestal portion having a plurality of nodes therein to electrically connect with the electrical connecting point of the male bolt portion, each of the nodes electrically connecting with a corresponding signal transmission path respectively;
• and providing a RFID system, the RFID system having a RFID chip embedded inside the bolt, a transmission conductor electrically connecting with the RFID chip and the electrical connecting point of the male bolt portion, and an antenna installed on the bolt pedestal and electrically connecting with at least one of the nodes through the corresponding signal transmission path;
• wherein after the bolt and the bolt pedestal is securely locked with each other, the RFID chip selectively and electrically connects through the transmission conductor, the electrical connecting point of the male bolt portion to at least one of the nodes, so that a corresponding RFID signal can be transmitted through one of the corresponding signal transmitting paths and the then antenna;
• the multi-secured protection method further comprising the step of:
• providing a protection circuit, the protection circuit electrically connecting with the RFID chip and the antenna after the bolt and the bolt pedestal being securely fastened, wherein when the bolt and the bolt pedestal is separated after being securely fastened, the protection circuit become disconnected so that the RFID chip fails to electrically connect with the antenna.
