Example one
An NFC card data writing system according to an embodiment of the present invention may have a structure as shown in fig. 1, and includes a mobile terminal 11 (e.g., a mobile phone, a tablet computer, or a smart watch), a server 12, and a smart door lock 13, where a client 111 installed on the mobile terminal 11 is bound to the smart door lock 13 through a login account, where:
the client 111 is configured to send an identifier verification request to the server, where the identifier verification request carries the login account and a near field communication card identifier in a near field communication card read through a near field communication function of the mobile terminal; the secret key data sent by the server are received, and the received secret key data and the read near field communication card identification are sent to the intelligent door lock; setting a success message according to the secret key sent by the intelligent door lock, clearing secret key data in the near field communication card through a near field communication function of the mobile terminal, and writing the received secret key data into the near field communication card;
the server 12 is configured to receive the identifier verification request, add key data corresponding to the near field communication card identifier carried in the identifier verification request to a blacklist if it is determined that the near field communication card identifier belongs to the near field communication card identifier corresponding to the smart door lock bound to the determined login account, re-generate key data for the near field communication card identifier, and send the re-generated key data to the client; receiving a key verification request sent by the intelligent door lock, and if the key data carried in the key verification request belongs to the key data corresponding to the near field communication card identifier carried in the key verification request, sending a verification passing message to the intelligent door lock;
the smart door lock 13 is configured to receive the key data and the nfc card identifier sent by the client, send a key verification request to the server, where the key verification request carries the received key data and the received nfc card identifier, set the received key data as legal key data if a key verification passing message sent by the server is received, and return a key setting success message to the client.
It should be noted that the server 12 may determine the nfc card identifier corresponding to the smart door lock bound by the login account in the following manner:
and determining the bound intelligent door lock corresponding to the login account carried in the identification verification request according to the corresponding relation between the stored login account and the bound intelligent door lock, and determining the near field communication card identifier corresponding to the bound intelligent door lock corresponding to the login account carried in the identification verification request according to the corresponding relation between the stored intelligent door lock and the near field communication card identifier.
The server 12 may determine whether the key data carried in the key verification request belongs to the key data corresponding to the nfc card identifier carried in the key verification request by:
and determining whether the key data carried in the key verification request belongs to the key data corresponding to the near field communication card identifier carried in the key verification request according to the corresponding relationship between the stored NFC card identifier and the key data.
The server 12 is further configured to, if it is determined that the near field communication card identifier does not belong to the determined near field communication card identifier corresponding to the smart door lock bound to the login account, return an identifier verification failure message to the client;
the client 111 is further configured to receive the identifier verification failure message, determine that the card needs to be rewritten continuously according to the identifier verification failure message, and send a card rewriting continuous request to the server;

It should be noted that, if the server rewrites the NFC card according to the request for continuously rewriting the card sent by the client, a correspondence between the NFC card identifier and the smart door lock needs to be further established, which can be understood as adding the NFC card identifier into the NFC card identifier corresponding to the smart door lock, and updating the NFC card identifier corresponding to the smart door lock, so that the server subsequently performs related operations according to the correspondence between the updated smart door lock and the near-field communication card identifier, for example, determining the near-field communication card identifier corresponding to the bound smart door lock corresponding to the login account carried in the identifier verification request.
Corresponding to the system provided in the first embodiment, the following method is provided.
Example two
An embodiment of the present invention provides a method for writing data into an NFC card, where the method is applied to a client installed on a mobile terminal, the client is bound to an intelligent door lock through a login account, the mobile terminal has a near field communication function, and a flow of steps of the method may be as shown in fig. 2, where the method includes:
step 101, sending an identification verification request to a server.
In this step, the client may send an identifier verification request to the server, where the identifier verification request carries the login account and the nfc card identifier in the nfc card read through the nfc function of the mobile terminal.
And step 102, receiving the key data sent by the server.
In this step, the client may receive the key data sent by the server.
The secret key data can be understood as secret key data generated for the near field communication card identifier again by adding the secret key data corresponding to the near field communication card identifier carried in the identifier verification request to a blacklist if the server determines that the near field communication card identifier belongs to the determined near field communication card identifier corresponding to the smart door lock bound to the login account.
And 103, sending the received key data and the read near field communication card identification to the intelligent door lock.
In this step, the client may send the received key data and the read near field communication card identifier to the smart door lock, so that after the validity of the key data is verified by the smart door lock, the key data is set as valid key data, and the smart door lock can be subsequently unlocked by the key data.
And step 104, rewriting the data.
In this step, if the client receives a successful key setting message sent by the smart door lock, the client can clear the key data in the near field communication card through the near field communication function of the mobile terminal, write the received key data into the near field communication card, and complete the card rewriting operation of the near field communication card, so that the near field communication card can unlock the smart door lock by using the rewritten key data, thereby ensuring the timeliness and convenience of the card rewriting operation and further ensuring the security of the smart door lock.
It should be noted that, after step 101 and before step 102, the present embodiment may further include the following steps:
step 102', receiving the identification verification failure message sent by the server.
In this step, the client may receive an identity verification failure message sent by the server. And can verify the failing message according to the received identification, confirm whether it needs to continue rewriting the card.
The message that the identification authentication fails can be understood as that the message is sent when the server determines that the near field communication card identification does not belong to the determined near field communication card identification corresponding to the smart door lock bound by the login account after receiving the identification authentication request.
If the client confirms that the card needs to be rewritten continuously, a continuous card rewriting request can be sent to the server. The server may proceed with step 102 in accordance with the resume rewrite card request. Of course, if the client confirms that the card does not need to be rewritten, the flow may be ended.
In a possible implementation manner, the client may verify that the failure message is received according to the identifier, prompt the user that the NFC card is not the NFC card matching the smart door lock, for example, display a dialog box in which a text prompt that the NFC card is not the NFC card matching the smart door lock failed is displayed, and may further ask the user whether the card rewriting operation needs to be continued, for example, display a dialog box including a continue button and an end button, and may confirm that the user needs to continue rewriting the card by clicking the continue button by the user, and confirm that the user does not need to continue rewriting the card by clicking the end button by the user. If it is determined that the card needs to be rewritten further, the client may send a request to the server to rewrite the card further.
It should be noted that, when the server generates the key data, it is necessary to establish a correspondence between the near field communication card identifier and the smart door lock, in addition to adding the key data corresponding to the near field communication card identifier carried in the identifier verification request to the blacklist, re-generating the key data for the near field communication card identifier, and sending the re-generated key data to the client.
EXAMPLE III
An embodiment of the present invention provides a method for writing data into an NFC card, where the method is applied to a server, and a flow of the steps of the method may be as shown in fig. 3, where the method includes:
step 201, receiving an identifier verification request sent by a client.
In this step, the server may receive an identifier verification request sent by the client, where the identifier verification request carries the login account and the nfc card identifier.
Step 202, determining whether the near field communication card identification is legal.
In this step, the server may determine that the nfc card identifier belongs to the determined nfc card identifier corresponding to the smart door lock bound to the login account, if the nfc card identifier does not belong to the determined nfc card identifier, the step 203 may be continuously performed, otherwise, the step 204 may be performed.
Step 203, an identification verification failure message is returned to the client.
If the server determines that the near field communication card identification does not belong to the determined near field communication card identification corresponding to the intelligent door lock bound by the login account, an identification verification failure message can be returned to the client so as to inform the client that the NFC card is not the NFC card matched with the intelligent door lock.
If a request for continuing rewriting the card is received, which is sent by the client, step 204 may be continuously executed, otherwise, the process may be ended.
And step 204, sending the regenerated key data to the client.
If it is determined that the near field communication card identifier belongs to the determined near field communication card identifier corresponding to the smart door lock bound to the login account, in this step, the server may add key data corresponding to the near field communication card identifier carried in the identifier verification request to a blacklist, generate key data for the near field communication card identifier again, and send the generated key data to the client.
If it is determined that the near field communication card identifier does not belong to the determined near field communication card identifier corresponding to the smart door lock bound to the login account, and a card rewriting request sent by the client is received, in this step, the server may establish a correspondence between the near field communication card identifier carried in the identifier verification request and the smart door lock, add key data corresponding to the near field communication card identifier to a blacklist, generate key data for the near field communication card identifier again, and send the generated key data to the client.
And step 205, receiving a key verification request sent by the intelligent door lock.
In this step, the server may receive a key verification request sent by the smart door lock, where the key verification request carries key data and the nfc card identifier.
Step 206, verifying the validity of the key.

EXAMPLE five
An embodiment of the present invention provides a data writing method for an NFC card, where a flow of the steps of the method may be as shown in fig. 5, and the method includes:
step 401, the client starts the card rewriting function.
In this step, the user can log in the client through the login information (login account and login password), and the client receives the login information to realize the user login.
After the user logs in, the client can start the card rewriting function. The client initiating the card re-write function may be triggered by the user, for example, by the user selecting the card re-write function in the client to trigger the client to begin re-writing the card.
It should be noted that, in order to implement the card rewriting of the client, in this step, the NFC card may be placed at a proper position, so that when the client rewrites the card, the mobile terminal where the client is located may read the NFC card through the NFC function.
Step 402, the client reads the NFC card.
In this step, the client may read the NFC card identifier and the key data in the NFC card through the NFC function of the mobile terminal.
Step 403, the client requests the server to perform NFC card verification.
In this step, the client may send an identifier verification request to the server, where the identifier verification request carries the login account and the read NFC card identifier.

In this step, the server may add the key data corresponding to the NFC card identifier carried in the identifier verification request to the blacklist, and delete the door opening qualification of the key data.
Step 406, the server regenerates the key data.
In this step, the server may generate key data for the NFC card identifier in the identifier verification request again according to a key generation rule of the smart door lock, establish a corresponding relationship between the key data and the NFC card identifier, and send the generated key data to the client.
It should be noted that, if the server executes step 405 and step 406 according to the request for continuously rewriting the card sent by the client, in this step, it is also necessary to establish a corresponding relationship between the near field communication card identifier carried in the identifier verification request and the corresponding smart door lock.
After receiving the key data, the client may send the received key data and the read NFC card identifier to the smart door lock.
Step 407, the server performs a key validity verification.
After the smart door lock receives the key data and the NFC card identifier sent by the client, in this step, a key verification request may be sent to the server, where the key verification request carries the received key data and the received NFC card identifier.
After receiving the key verification request sent by the intelligent door lock, the server can verify the validity of the key. The method includes the steps that whether secret key data carried in a secret key verification request belong to secret key data corresponding to a near field communication card identifier carried in the secret key verification request or not can be determined according to the corresponding relation between a stored NFC card identifier and the secret key data, if the secret key data carried in the secret key verification request belong to the secret key data corresponding to the near field communication card identifier carried in the secret key verification request, a secret key verification passing message is sent to an intelligent door lock, otherwise, a secret key verification failing message can be sent to the intelligent door lock, so that the intelligent door lock returns a secret key illegal message to a client side, the client side can finish a card rewriting process according to the secret key illegal message.
And step 408, setting key data for the intelligent door lock.
In this step, if the smart door lock receives the key verification passing message, the received key data sent by the client may be set as legal key data, the smart door lock is allowed to be unlocked by using the key data, and a key setting success message may be returned to the client.
And step 409, rewriting data into the NFC card by the client.
In this step, the client may set a success message according to the key sent by the smart door lock, clear the key data in the NFC card through the NFC function of the mobile terminal, write the received key data sent by the server into the NFC card, and write the key data into the NFC card may be understood as writing the key data into the data block of the NFC card.
