The unlocking device 100 includes: the system comprises a first main controller module 10, an identity acquisition module 20, a data transceiver module 30, an input/output module 40 and a first wired transmission module 50.

Specifically, the first master controller module 10 is configured to receive and process information sent by each module, and send corresponding control information to the corresponding module, so that the unlocking device 100 can normally complete unlocking, locking and basic communication functions.

Specifically, the identity acquisition module 20 is connected with the first master controller module 10. The identity acquisition module 20 is used for acquiring identity information and transmitting the identity information to the first master controller module 10. The use of the unlocking device 100 needs to verify the identity information of the user, and the unlocking device 100 can be used for locking and unlocking the electronic lock 200 after the identity information is verified to be correct, so that the safety of the packaging bag is greatly improved. The identity acquisition module 20 may include a fingerprint sensor for acquiring a fingerprint of a user for authentication. However, the present invention is not limited to this, and the identity acquisition module 20 may also include an iris recognition device for acquiring the iris to perform authentication.
