Unpacking method and device based on wifi network

The invention provides an unpacking method and an unpacking device based on a wifi network. The method comprises the following steps: scanning a two-dimensional code by a first user terminal through a wifi network, thereby obtaining an identify label ID of a cabinet terminal; transmitting an unpacking request information to a server, wherein the unpacking request information comprises the ID and the identity information of the cabinet terminal. The device comprises an identity label acquiring unit and an unpacking request information transmitting unit; by the identity label acquiring unit, the first user terminal scans the two-dimensional code through the wifi network so as to obtain the identity label ID of the cabinet terminal; the unpacking request information transmitting unit is used for transmitting the unpacking request information to the server; the unpacking request information comprises the ID and the identity information of the cabinet terminal. By adopting the unpacking method and the unpacking device, the delivery efficiency can be improved.
