Electronic seals (100, 200, 300) and electronic lock (500), and an implementation method for the electronic seals (100, 200, 300). The electronic seals (100, 200, 300) can be removably attached to the outer surface of an object to be sealed, the electronic seals (100, 200, 300) comprising: removal sensors (321, 3211), configured to be in a different state when the electronic seals (100, 200, 300) are attached to the outer surface of the object to be sealed and when the electronic seals (100, 200, 300) are not attached to the object to be sealed; a control unit (323), configured to determine the state of the electronic seals (100, 200, 300) at least partially on the basis of the state of the removal sensors (321, 3211); and a communication unit (325), configured to implement communication with an external device to send data of the state of the electronic seals (100, 200, 300). |
