[0045] The "NFC" mentioned in the embodiments of the present disclosure refers to a near field communication technology; the "POS" refers to a terminal with a transaction function; the "UWB" refers to an ultra-wideband wireless communication technology.

[0046] The balance query echo method provided in the embodiments of the present disclosure can be applied to a wallet application terminal, a POS terminal and the like. In the following, the balance query echo method in the embodiments of the present disclosure is introduced by taking the wallet application terminal and the POS terminal as examples.

[0047] As shown in FIG. 1, the embodiments of the present disclosure provide a balance query echo system 100 that can run the balance query echo method in the embodiments of the present disclosure, which includes a terminal 110, a target hard wallet 120 and a background system 130.

[0048] As shown in FIG. 2, the embodiments of the present disclosure provide a balance query echo method according to the balance query echo system 100 shown in FIG. 1, which includes:

[0049] S210: The user clicks the "hard wallet balance query" button on the terminal 110, and the terminal 110 responds to the balance query operation and waits for the target hard wallet 120 to paste the card. When the target hard wallet 120 pastes the card to the terminal 110, the terminal 110 is connected with the target hard wallet and obtains the wallet information from the target hard wallet. In some embodiments of the present disclosure, the terminal 110 can be connected with the target hard wallet through NFC, Bluetooth, UWB and the like.

[0050] In some embodiments of the present disclosure, the terminal 110 sends an operation instruction to the target hard wallet 120 after responding to the balance query operation, and the target hard wallet 120 returns the wallet information to the terminal 110 according to the operation instruction. In some embodiments of the present disclosure, the wallet information can include the identification of the target hard wallet or the association code of the target hard wallet. The association code of the target hard wallet and the identification of the target hard wallet are maintained in a mapping relationship in the background system, and the background system can identify and obtain the identification of the target hard wallet through the association code of the target hard wallet.

[0051] In some embodiments of the present disclosure, the terminal 110 can be a wallet application terminal or a POS terminal.

[0052] In some embodiments of the present disclosure, the transaction state of the terminal 110 has multiple states, such as a balance query state, a payment state, a management setting state, and an idle state. In some embodiments of the present disclosure, the terminal 110 sets the transaction state of the terminal 110 to the balance query state in response to the balance query operation, so as to verify the transaction state subsequently.

[0053] In some embodiments of the present disclosure, when the terminal 110 is a wallet application terminal, the wallet information obtained by the terminal 110 from the target hard wallet 120 further includes balance reading information. Subsequently, the terminal 110 verifies whether the latest balance information obtained from the background system 130 is consistent.

[0054] S220: The terminal 110 sends a balance query request to the background system 130 according to the wallet information. In some embodiments of the present disclosure, the balance query request includes the wallet information.

[0055] S230: The background system 130 returns the latest balance information of the target hard wallet 120 and a echo instruction to the terminal 110 after verifying the target hard wallet.

[0056] In some embodiments of the present disclosure, the background system 130 obtains the background wallet information according to the wallet information, and returns the latest balance information of the target hard wallet 120 and an echo instruction to the terminal 110 after confirming that the target hard wallet supports the display function according to the background wallet information. In some embodiments of the present disclosure, the background system 130 maintains the background wallet information of the target hard wallet 120, and the background wallet information includes a wallet type. When the wallet type is a visible wallet type, the target hard wallet supports the display function.

[0057] In some embodiments of the present disclosure, the user can also set the balance query password of the target hardware wallet 120. For example, the user operates the wallet application terminal to establish a connection with the target hardware wallet 120, and then sets the balance query password of the target hardware wallet 120 through the wallet application terminal. The balance query password is sent to the background system 130 and stored in the background wallet information. When the target hardware wallet 120 is set with a balance query password, the background system 130 receives a balance query request, confirms from the background system that the target hardware wallet balance query needs to be verified through the background wallet information, and sends a response that needs to be verified to the terminal 110. The terminal 110 generates a verification prompt information, and then broadcasts or displays the verification prompt information. The user inputs the balance query password of the target hardware wallet on the terminal 110. The terminal 110 sends the password information to the background system 130. After the background system 130 verifies the password information, the latest balance information and echo instruction are sent to the terminal 110.

[0058] In some embodiments of the present disclosure, when the terminal 110 is a POS terminal, and the POS terminal directly interfaces with the operating agency, as shown in FIG. 3, the background system 130 includes a POS terminal operating agency. The POS terminal sends a balance query request to the POS terminal operating agency. The POS terminal operating agency obtains the operating agency corresponding to the target hardware wallet 120 according to the wallet information in the balance query request, judges whether the operating agency corresponding to the target hardware wallet 120 is the agency, and if so, returns the latest balance information and echo instruction to the POS terminal according to the balance query request. If not, as shown in FIG. 4, the balance query request is sent to the operating agency corresponding to the target hardware wallet 120 through an interconnection system. The operating agency corresponding to the target hardware wallet 120 performs verification processing, and then returns the latest balance information and echo instruction to the POS terminal operating agency through the interconnection system. The POS terminal operating agency sends the latest balance information and echo instruction to the POS terminal. In this case, the background system 130 also includes the above-mentioned interconnection system and the operating agency corresponding to the target hardware wallet 120.

[0059] In some embodiments of the present disclosure, when the terminal 110 is a POS terminal, as shown in FIG. 5, when the POS terminal is connected to the operation agency through the receiving agency, the background system 130 includes the receiving agency, the interconnection system, the operation agency corresponding to the target hard wallet 120. The terminal 110 sends the balance query request to the receiving agency, the receiving agency obtains the operation agency information corresponding to the target hard wallet 120 according to the wallet information, and then forwards the balance query request to the operation agency corresponding to the target hard wallet 120 through the interconnection system. The operation agency corresponding to the target hard wallet 120 verifies the wallet information, returns the latest balance information and echo instruction to the receiving agency through the interconnection system, and the receiving agency returns the latest balance information and echo instruction to the terminal 110.

[0060] In some embodiments of the present disclosure, when the terminal 110 is a wallet application terminal, as shown in FIG. 6, the background system 130 includes a wallet background, an interconnection system, and an operation agency corresponding to the target hard wallet 120. The terminal 110 sends the balance query request to the wallet background, the wallet background judges to obtain the information of the operation agency corresponding to the target hard wallet 120 according to the wallet information, and then sends the balance query request to the operation agency corresponding to the target hard wallet 120 through the interconnection system. The operation agency corresponding to the target hard wallet 120 verifies the wallet information, sends the latest balance information and echo instruction to the wallet background through the interconnection system, and the wallet background sends the latest balance information and echo instruction to the terminal 110. In some embodiments of the present disclosure, a plurality of soft wallets under different operation agencies can be accessed on the wallet application terminal, and the balance of the hard wallet opened by any operation agency can be queried under any soft wallet.

[0061] In the above-mentioned background system 130, when the operation agency corresponding to the target hard wallet 120 needs to verify the background wallet information, the transmission path of the related response needing to be verified and the subsequent user input password is consistent with the transmission path of the balance query request or the transmission path of the latest balance information.

[0062] S240: The terminal 110 sends the latest balance information and echo instruction to the target hard wallet 120 in response to the target hard wallet 120 still being in a connected state. In some embodiments of the present disclosure, when the terminal 110 is a wallet application terminal, the terminal 110 also compares the balance reading information obtained previously with the latest balance information, judges that the latest balance information is inconsistent with the balance reading information, and sends the latest balance information and echo instruction to the target hard wallet 120, and judges that the latest balance information is consistent with the balance reading information, and then prompts the user that the balance has not been updated, and the latest balance information and echo instruction can not be sent to the target hard wallet 120.

[0063] S250: The target hardware wallet 120 displays the latest balance information. In some embodiments of the present disclosure, the target hardware wallet 120 echoes and stores the latest balance information according to the echo instruction, and can first clear the balance information displayed by the target hardware wallet 120, and then display the latest balance information.

[0064] In the embodiments of the present disclosure, when the terminal 110 returns the latest balance information to the target hardware wallet, it is necessary to first determine whether it is still in a connection state with the target hardware wallet 120. If it is in a connection state, the latest balance information and the echo instruction are sent to the target hardware wallet 120. If it is determined that the connection with the target hardware wallet is disconnected, the terminal 110 will first read its own transaction state. If the transaction state has not changed and is still in a balance query state, the user can be prompted to reattach the card to receive the latest balance information. Specifically, as shown in FIG. 7, the method in the embodiments of the present disclosure further includes:

[0065] S260: In response to being in a disconnected state with the target hardware wallet 120, the terminal 110 generates balance echo failure information, confirms that the transaction state of the terminal 110 is a balance query state, generates a connection establishment prompt information, and after reestablishing the connection with the target hardware wallet 120, sends the latest balance information and the echo instruction to the target hardware wallet 120. If the transaction state has been changed to other transaction states, the user needs to reattach the card, re-read the wallet information, and initiate a balance query request.

[0066] In some embodiments of the present disclosure, when the target hardware wallet 120 returns the wallet information, it can generate a balance query sequence number and set the balance query sequence number to the wallet information. The balance query sequence number is used to identify each independent balance query request. The corresponding operating agency of the target hardware wallet will also attach the balance query sequence number when returning the latest balance information to the terminal 110. When the terminal 110 returns the latest balance information to the target hardware wallet 120, the terminal 110 interacts with the target hardware wallet 120 to determine whether the latest balance information corresponds to the latest balance query request. If so, the latest balance information and the echo instruction are received and displayed. If the target hardware wallet 120 determines that the balance query sequence number received through the interaction is not the latest balance query sequence number, the target hardware wallet refuses to receive the latest balance information and the echo instruction. In the above scenario, when the terminal 110 responds to the disconnection with the target hardware wallet, in addition to determining the transaction state, after reconnection with the target hardware wallet, it is also determined whether the balance query sequence number of the interaction is the latest sequence number. If not, the target hardware wallet refuses to receive the latest balance information and the echo instruction. In this way, it can be ensured that the returned latest balance information corresponds to the latest balance query request, avoiding invalid display of the latest balance information and reducing user experience.

[0067] For example, when the target hardware wallet interacts with the first terminal for balance inquiry, a balance inquiry serial number 20240620103752001 is generated and set in the wallet information. When the first terminal subsequently receives the latest balance information, the balance inquiry serial number attached is 20240620103752001. At this time, the target hardware wallet is disconnected from the first terminal, and the first terminal is still in the balance inquiry state within the state valid time. The user performs a transaction with the second terminal, and the background changes the balance of the target hardware wallet. At this time, the user performs a query with the third terminal, generates a balance inquiry serial number 20240620103830001, and then the user disconnects the target hardware wallet from the third terminal. When the first terminal is still in the balance inquiry state, the user again performs a card sticking with the first terminal to receive the latest balance information. At this time, the target hardware wallet acquires the balance inquiry serial number from the first terminal, which is not the latest, and thus refuses to receive the latest balance information.

[0068] In some embodiments of the present disclosure, the balance inquiry state of the terminal 110 includes not only the state value but also the information of the transaction counterparty (for example, the wallet association code described above). When the target hardware wallet is disconnected from the terminal and then receives the latest balance information again, the wallet association code of the target hardware wallet is read, and the read wallet information is compared with the wallet association code in the balance inquiry state. If they are consistent, the latest balance information and the echo instruction are issued to the target hardware wallet. If they are inconsistent, the user is prompted to perform a re-query.

[0069] In some embodiments of the present disclosure, when the target hardware wallet performs balance inquiry, the transaction state of the target hardware wallet can also be set to the balance inquiry state, and the balance inquiry state includes not only the state value but also the information of the transaction counterparty (for example, the terminal identifier). When the target hardware wallet is disconnected from the terminal and then receives the latest balance information again, the terminal identifier is read, and the read terminal identifier is compared with the terminal identifier in the balance inquiry state, or on the basis of the state verification of the terminal described above, it is determined whether to receive the latest balance information. When they are consistent, the latest balance information is received. When they are inconsistent, the latest balance information is not received.

[0070] In some embodiments of the present disclosure, the terminal 110 can be configured with a transaction state valid time parameter. For example, when the transaction state of the terminal 110 is triggered to become the balance inquiry state, the valid time of the transaction state can be 1 minute. If the balance inquiry is not completed within 1 minute, the transaction state is switched.

[0071] In some embodiments of the present disclosure, the balance query method described above can also be executed after the user transfers out the balance of the wallet. Before the terminal 110 responds to the balance query operation, the terminal 110 (for example, the wallet application terminal described above) sends a balance clearing instruction to the target hard wallet 120 in response to the operation of reducing the balance of the target hard wallet, and the target hard wallet 120 clears the displayed balance information. The user then pastes the card again to query the balance. In the embodiments of the present disclosure, the balance transfer requires the user to perform the card pasting operation, and then a series of operations such as the decryption operation and the like, which requires a period of time, and the balance cannot be updated during this period of time. In order to avoid the user's misunderstanding of the balance information, the balance in the target hard wallet is first cleared.

[0072] In some embodiments of the present disclosure, the balance query method described above can also be executed after the user transfers in the balance of the wallet. When the balance is transferred in, the target hard wallet can not establish a connection with the terminal, and the background changes the balance of the wallet. After the operation is completed, the user can paste the card, the target hard wallet establishes a connection with the terminal, and the balance in the target hard wallet is updated.

[0073] As shown in FIG. 8, in the balance query echo system 100 in the embodiments of the present disclosure, the initial balance of the target hard wallet is 101 yuan. When the target hard wallet 120 is pasted with the terminal 110, the terminal sends the wallet information to the background 130. After the background 130 processes, the latest balance information is returned to the terminal 110. When the terminal 110 and the target hard wallet 120 are still in a connected state, the terminal 110 sends the latest balance 95 yuan of the target hard wallet 120 to the target hard wallet 120, and the target hard wallet 120 displays it. When the terminal 110 and the target hard wallet 120 are disconnected, the terminal 110 generates a balance echo failure information. The terminal 110 confirms that the transaction state is still in the balance query state, and then generates a connection establishment prompt information to prompt the user to paste the card again. When the user pastes the card again, the terminal 110 establishes a connection with the target hard wallet 120 again. The terminal 110 sends the latest balance 95 yuan to the target hard wallet 120, and the target hard wallet 120 displays the latest balance. In the embodiments of the present disclosure, after the terminal 110 receives the latest balance information, the terminal 110 can also display the latest balance information, so that the user can quickly know the balance of the hard wallet.

[0074] The method in the embodiments of the present disclosure provides a balance query function for the use scenario of the visual hard wallet. The user can directly obtain the balance information from the target hard wallet, and can directly view the balance information from the target hard wallet before the next transaction. The user operation is more convenient, and the experience is improved.
