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.
Claims14
An electronic seal comprising:
- a main body defining a chamber having an inlet;
- an insertion bolt provided to be inserted successively into a door latch, said inlet and then said chamber of said main body in order to fasten said door latch;
- a snapping member disposed in said chamber to fasten said insertion bolt when said insertion bolt is inserted into said chamber;
- and
- an RFID chip stored with an identification code and configured to allow said identification code to be read out by a host when said insertion bolt is fastened by said snapping member and disallow said identification code to be read out by said host when said insertion bolt is broken.

A system for container management comprising:
- an electronic seal including an RFID chip stored with an identification code therein and an antenna, wherein said RFID chip is normally disconnected to said antenna and is electrically coupled to said antenna only when said electronic seal seals a door latch of a container;
- and said RFID chip is disconnected with said antenna when said electronic seal is broken, and
- an identification host capable of transmitting a magnetic wave to RFID chip of said electronic seal, receiving an identification magnetic wave carrying said identification code from said RFID chip and demodulating said identification magnetic wave to obtain said identification code;
- wherein when said RFID chip is electronically coupled with said antenna, said RFID chip of said electronic seal is ready to receive said magnetic wave from said identification host and then transmit said identification magnetic wave carrying said identification code back to said identification host and whereby said host can demodulate said identification magnetic wave to read out said identification code.
