Kit comprising a housing and at least one label that can be positioned on an object and having an identifier of the object, the secure-closure housing comprising a door movable between a closed position and an open position, the housing comprising a locking device adapted to lock the door in the closed position, and comprising furthermore: - a means for accessing an identifier of an object, which is then the received object identifier; - a means for accessing an authenticator of a user who is to deposit the object; - means for authenticating a candidate user to determine whether the candidate user corresponds to the authenticator of the user who is to deposit the object; - a device for identifying an object present in the housing, which provides an identifier of the object or absence of identification of the object in the housing; - a controller of the locking device, designed such that . when the door is closed and the identification device of an object indicates an absence of identification of an object in the housing, an unlock command is sent to the locking device only after authentication of the user who is to deposit the object; . a lock command is sent after the identification device of an object has provided an identifier of an object that corresponds to the object identifier received; and . an alarm is triggered and the locking of the door is prevented when the identification device of an object provides an identifier of an object that does not correspond to the object identifier received; wherein the means for authenticating the candidate user, to determine whether the candidate user corresponds to the authenticator of the user who is to deposit the object, comprises a means for reading, outside the housing, the identifier carried by the object, and determining whether the identifier read corresponds to the object identifier received. - a means for accessing an identifier of an object, which is then the received object identifier; - a means for accessing an authenticator of a user who is to deposit the object; - means for authenticating a candidate user to determine whether the candidate user corresponds to the authenticator of the user who is to deposit the object; - a device for identifying an object present in the housing, which provides an identifier of the object or absence of identification of the object in the housing; - a controller of the locking device, designed such that . when the door is closed and the identification device of an object indicates an absence of identification of an object in the housing, an unlock command is sent to the locking device only after authentication of the user who is to deposit the object; . a lock command is sent after the identification device of an object has provided an identifier of an object that corresponds to the object identifier received; and . an alarm is triggered and the locking of the door is prevented when the identification device of an object provides an identifier of an object that does not correspond to the object identifier received; . when the door is closed and the identification device of an object indicates an absence of identification of an object in the housing, an unlock command is sent to the locking device only after authentication of the user who is to deposit the object; . a lock command is sent after the identification device of an object has provided an identifier of an object that corresponds to the object identifier received; and . an alarm is triggered and the locking of the door is prevented when the identification device of an object provides an identifier of an object that does not correspond to the object identifier received; <EOS>
