here, the second activation record is an activation record corresponding to the NFC tag that successfully completes the local activation;
Step D2, taking each second activation record as a corresponding current activation record, and taking a second tag identification field of the current activation record as corresponding current tag identification data; in the label issuing database, a label issuing data record with a label identification field matched with the current label identification data is used as a corresponding current label issuing data record; updating the label activation state field of the current label issuing data record into a remote activation state; if the updating is successful, setting the corresponding first record updating state as a successful state, and if the updating is failed, setting the corresponding first record updating state as a failed state;
step D3, if all the obtained first record updating states are successful states, a remote activating result which is specifically set as successful remote updating is sent back to the tag activating equipment; if at least one first record updating state is a failure state, extracting a second tag identification field of a second activation record corresponding to the first record updating state which is the failure state as a corresponding first failure tag identification, and forming a corresponding remote activation result by all the obtained first failure tag identifications to send back to the tag activation equipment.
In addition, it should be noted that, when displaying the remote activation result, the tag activation device also extracts each first failure tag identifier in the remote activation result that is not successful in remote update as a corresponding reset tag identifier, and extracts a second tag identifier field of the first activation record in which the first activation state field in the first activation list is in a local inactive state as a corresponding reset tag identifier; extracting a first data block identification field of a first configuration record, in which a first tag identification field in a first configuration list is matched with each reset tag identification, as a corresponding reset tag data block identification set; and resetting the data block access states of all the data storage blocks matched with the corresponding reset tag data block identification sets on the first NFC tag corresponding to each reset tag identification to an unreadable and writable state. In this way, the data block access state of the data storage blocks of all the first NFC tags which are failed in the secondary activation (including the local activation failure and the remote activation failure) can be restored to the state when the last step of filling the release data is completed, so that no readable risk exists in the release data of all the first NFC tags which are failed in the activation.
When the data block access states of all the data storage blocks matched with the corresponding reset tag data block identification sets on the first NFC tag corresponding to each reset tag identification are reset to the unreadable and writable state:
the processing steps of the label activating device side comprise: the tag activation device takes a first NFC tag corresponding to the current reset tag identifier and a reset tag data block identifier set as a corresponding current NFC tag and current data block identifier set; traversing each first data block identifier of the current data block identifier set, taking the first data block identifier of the current traversal as a corresponding current data block identifier, sending a data block deactivation instruction carrying the current data block identifier to the current NFC tag, and receiving a fourth instruction execution state returned by the current NFC tag;
the corresponding processing steps of the current NFC label side comprise: the current NFC tag identifies a sending instruction of the tag activation equipment; when the sending instruction is a data block deactivation instruction, extracting a current data block identifier from the data block deactivation instruction; and resetting the data block access state of the data storage block with the data block identification matched with the current data block identification in the issuing data storage area to an unreadable and writable state, and sending back a fourth instruction execution state of the specific successful state to the tag activation equipment when the data block access state is successfully reset.
