Abstract: A tie includes an RFID device and a body encapsulating the RFID device by overmolding. The body includes a strap member, a head member, and a protection member connected between the strap member and the head member. The strap member has a plurality of engaging teeth. The RFID device is embedded in the protection member. The head member has a through hole. A hole wall of the through hole is provided with a one-way pawl. When winding the body around an object, the protection member can get a better protection since the protection member is located on an inner side between the head member and the strap member without protruding outward. Because the protection member and the head member are closer to a surface of the object, the extent to which the protection member protrudes outwards is reduced, thereby facilitating the RFID device to be sensed more easily.

Abstract: The present invention disclosed a radio-frequency identification (RFID) device. The RFID device comprises a protective body and a RFID circuit unit located inside the protective body. The RFID circuit unit comprises a printed circuit board (PCB), a RFID chip and an antenna disposed thereon. A front surface of the PCB faces a top surface of the protective body; a rear surface of the PCB faces a bottom surface of the protective body.

Abstract: An electronic seal system includes an electronic seal and a RFID reader. A passive RFID chip in the electronic seal has a configuration word and a seal state identification code inside. The value of the configuration word changes according to the state of the state configuration pins of the passive RFID chip. The state of the configuration pins is determined by the state of a bolt of the electronic seal. The RFID reader rewrites the seal state identification code according to the configuration word and the seal state identification code read by the RFID reader.

Abstract: An electronic seal includes a main body, an insertion bolt, and an identification circuit. Thus, the electronic seal has a determined identification code so that the identification host can rapidly identify the article (or storage space) sealed by the electronic seal, and the sealed article is identified and managed easily and conveniently by provision of the electronic seal, thereby saving the manual work.

Abstract: A system for monitoring a container includes a seal, a monitoring device and a communication center. The seal is used to lock the doors of the container. The doors can be opened only when the seal is broken or cut illegally. The monitoring device is connected to the seal when the doors are locked by the seal. The monitoring device is disconnected from the seal when the doors are released from the seal. The monitoring device detects the status and position of the seal when the doors are locked by the seal, and sends related data to the communication center so that the communication center can always determine the position of the container and whether the doors have been opened.
