The following examples further illustrate the aspects of the present invention in detail, but do not limit the scope of the present invention in any way.

Please refer to FIG. 1 , which is a block diagram of a bank transaction system based on Bluetooth communication according to an embodiment of the present invention. In this example, the bank transaction system 1 includes a Bluetooth shielding box 10 , a Bluetooth transceiver 20 and a computing device 30 , where the Bluetooth shielding box 10 has an accommodation space 100 , and the Bluetooth transceiver 20 is located in the accommodation space 100 so that the Bluetooth transceiver 20 The Bluetooth signal strength emitted by 20 is greater than or equal to a preset threshold within the accommodation space 100 and is less than the preset threshold outside the accommodation space 100 . The computing device 30 is connected to the Bluetooth transceiver 20 through line signals. Therefore, when the mobile device is located in the accommodation space 100, the Bluetooth transceiver can automatically move the device After receiving a pending transaction electronic document, it is sent to the computing device 30, and the computing device 30 can execute the transaction based on the pending transaction electronic document.

In this example, the Bluetooth shielding box 10 can be a shielding body of various shapes such as a shell, a plate, a sleeve, etc. made of conductive or magnetic conductive materials to limit the electromagnetic field within a certain spatial range. The structure of the Bluetooth shielding box 10 can be in various shapes with openings, and the edges of the openings can be arc-shaped or polygonal. In addition, part of the outer wall of the Bluetooth shielding box 10 may be transparent. Specifically, part of the outer wall of the Bluetooth shielding box 10 may be a transparent visible part. Accordingly, the user can place a mobile device (such as a mobile phone) in the accommodation space 100 for operation through the opening, and at the same time, the user can see the screen of the mobile phone through the transparent viewing portion.

In this example, the Bluetooth transceiver 20 is a device capable of sending and receiving Bluetooth signals, and the computing device 30 is a general central processing unit or microcontroller. It should be noted that in the implementation of multiple Bluetooth shielding boxes 10 and multiple Bluetooth transceivers 20 , a single computing device 30 can be connected to the multiple Bluetooth transceivers 20 , although the multiple Bluetooth transceivers 20 They cannot be connected to each other directly through signals (they can be connected indirectly through the computing device 30).

Please refer to FIG. 2 in conjunction with FIG. 1. FIG. 2 is an operation flow chart of a bank transaction system 1 based on Bluetooth communication according to an embodiment of the present invention. In this example, the operation flow of the bank transaction system 1 includes steps S20 to S24. Step S20 is: the Bluetooth transceiver 20 can use Bluetooth communication to connect to the mobile device in the Bluetooth shielding box 10 . Specifically, the computing device 30 can pre-store a default password set by the mobile device, so that when the mobile device sends a connection request to the Bluetooth transceiver 20, a password needs to be entered, and the Bluetooth transceiver 20 sends the password to the computing device. The device 30 and the computing device 30 will compare the password provided by the mobile device and the default password to determine whether the mobile device can be connected to the Bluetooth transceiver 20 . When the password provided by the mobile device is the same as the default When entering the password, the computing device 30 determines that the mobile device can be connected to the Bluetooth transceiver 20, that is, agrees to the connection request. Step S21 is: the Bluetooth transceiver 20 can search for all connectable devices in the accommodation space 100 of the Bluetooth shielding box 10 to ensure that there are no other communication devices within the shielding range that may cause signal interference or intervention. Specifically, the Bluetooth transceiver 20 may include a microcontroller. When the microcontroller in the Bluetooth transceiver 20 detects other connectable devices other than the mobile device, the microcontroller may immediately activate the Bluetooth transceiver 20 Disconnect the signal connection with the mobile device to ensure data security, and send a suspicious signal to the computing device 30. The computing device 30 can output a message corresponding to the suspicious signal through an external electronic device such as a display for relevant personnel to understand. Abnormal conditions are detected and the problem is eliminated, or the suspicious signal is first sent to the mobile device and the computing device 30 and then the signal connection with the mobile device is disconnected. It should be noted that step S21 may be executed before step S20. For example, when the microcontroller of the Bluetooth transceiver 20 detects multiple connectable devices, it may refuse to connect to any device and send a suspicious message. To the computing device 30, the Bluetooth transceiver 20 does not accept the connection request from the mobile device until there is only one mobile device left in the connectable range. In addition, it should be noted that the connectable devices of the above-mentioned Bluetooth transceiver 20 refer to devices whose Bluetooth signal strength is greater than or equal to the aforementioned preset threshold. Step S22 is: the Bluetooth transceiver 20 receives the electronic document of the pending transaction from the mobile device. The electronic document of the pending transaction can be an electronic account opening document, a transfer electronic form, a remittance electronic form and other over-the-counter transaction data. Step S23 is: the computing device 30 can receive the pending transaction electronic document through the Bluetooth transceiver 20 and execute the transaction according to the document. Specifically, when the Bluetooth transceiver 20 receives the pending transaction electronic document, the computing device 30 can identify according to a code on the pending transaction electronic document what type of transaction operation it is used for (such as account opening, transfer, remittance, etc. ), and then use optical character recognition (OCR) to process electronic documents for transactions The operational information such as personal information or account number is identified to provide the counter staff or the bank server with the transaction operation. Alternatively, the pending transaction electronic document may include text and numeric data input by the user through a graphical user interface (GUI) of the mobile device. When the Bluetooth transceiver 20 receives the pending transaction electronic document, the computing device 30 may use the pending transaction electronic document. The file name of the electronic document to be processed is used to identify the electronic document to be processed to confirm what kind of transaction operation it is used for, and then the text and digital data contained in the electronic document to be processed are obtained to obtain the remittance account and payment amount, etc. to provide Counter staff may perform transaction operations on the bank's server. However, it should be noted that the present invention can adopt other identification schemes for electronic files, which are not limited here. In addition, if the personal information in the transaction information filled in by the user does not match the default user personal information previously stored in the computing device 30 (for example, name, ID number, default password, etc.), the computing device 30 can send and receive via Bluetooth. The device 20 sends an error message to the mobile device. Step S24 is: after the transaction operation is completed, the computing device 30 sends a transaction completion message to the mobile device through the Bluetooth transceiver 20 . Steps S21 and S24 are optionally executed.

The computing device 30 is connected to the first Bluetooth transceiver 21 through a line signal, and the signal is connected to the second Bluetooth transceiver 22. The connection between the computing device 30 and the second Bluetooth transceiver 22 can be wired or wireless. When the mobile device is located outside the Bluetooth shielding box 10, the second blue The wireless transceiver 22 may receive a connection request from the mobile device and transmit the connection request to the computing device 30 . When the mobile device is located in the accommodation space 100, the first Bluetooth transceiver 21 can receive an original transaction electronic document from the mobile device and transmit it to the computing device 30, and the computing device 30 can execute the transaction based on the original transaction electronic document.

Please refer to FIG. 4 in conjunction with FIG. 3. FIG. 4 is an operation flow chart of an implementation mode of the bank transaction system 1' based on Bluetooth communication according to the embodiment of FIG. 3 of the present invention. In this embodiment, the operation flow of the bank transaction system 1' includes step S40 to step S44. Step S40 is: the second Bluetooth transceiver 22 receives a connection request from the mobile device located outside the Bluetooth shielding box 10 . Specifically, the connection request may include a password for connection and the type of transaction that the user wants to handle (such as transfer, account opening, etc.), where the password may be the same as the password in step S20, which will not be described again here. In addition, if the signal strength of the mobile device is lower than a predetermined threshold, that is, it is too far away from the second Bluetooth transceiver 22 or is located in the Bluetooth shielding box 10 , the second Bluetooth transceiver 22 cannot automatically receive the connection request from the mobile device. Step S41 is: the computing device 30 generates the original transaction electronic document and transmits it to the mobile device through the second Bluetooth transceiver 22 . Specifically, the second Bluetooth transceiver 22 can transmit the connection request to the computing device 30, and the computing device 30 can generate an original transaction electronic document corresponding to the transaction type according to the transaction type included in the connection request (if it has not been filled in yet). transfer electronic form, remittance electronic form, account opening electronic form, etc.) and transmit it to the mobile device through the second Bluetooth transceiver 22. In another implementation, the connection request does not include the type of transaction that the user wants to handle, and when the computing device 30 receives the connection request through the second Bluetooth transceiver 22, it will provide a variety of transactions through the second Bluetooth transceiver 22. Type of original transaction electronic document to mobile device. Step S42: The first Bluetooth transceiver 21 is connected to the mobile device in the Bluetooth shielding box 10. Step S43: The first Bluetooth transceiver 21 automatically receives the original Electronic documents for starting transactions, electronic documents for pending transactions can be electronic documents for account opening, electronic transfer forms, remittance electronic forms and other over-the-counter transaction information. Step S44: The computing device 30 receives the original transaction electronic document through the first Bluetooth transceiver 21 and executes the transaction according to the document. It should be noted that steps S42 to S44 in this implementation may be exactly the same as the above-mentioned steps S20, S22 and S23. That is to say, the first Bluetooth transceiver 21 may be exactly the same as the above-mentioned Bluetooth transceiver 20, and the original The transaction electronic document can be exactly the same as the above-mentioned pending transaction electronic document.

Please refer to FIG. 5 in conjunction with FIG. 3. FIG. 5 is an operation flow chart of another implementation mode of the bank transaction system 1' based on Bluetooth communication according to the embodiment of FIG. 3 of the present invention. In this embodiment, the operation flow of the bank transaction system 1' includes step S40, step S51, step S52, and step S42 to step S44. Step S40 is: the second Bluetooth transceiver 22 receives a connection request from the mobile device located outside the Bluetooth shielding box 10 . Step S51 is: the computing device 30 sends a biometric recognition request to the mobile device through the second Bluetooth transceiver 22. For example, the biometric recognition may include facial recognition, voiceprint recognition, fingerprint recognition, etc. Step S52 is: when the mobile device receives the biometric identification request, it may receive a biometric feature to be identified based on the biometric identification function of the mobile device itself. For example, the mobile device may use a camera to capture the user's face to obtain the facial feature to be identified. Or use the fingerprint touch panel to obtain the user's fingerprint characteristics to be identified. After the computing device 30 determines that the biometric characteristics to be identified match the predetermined biometric characteristics, it generates the original transaction electronic document and transmits it to the mobile device through the second Bluetooth transceiver 22. The predetermined biometric characteristics are the user's identification stored in the database in advance. Biometric data, for example, can be facial recognition features captured from multiple facial photos, or voiceprint recognition features captured from a user's pre-recorded audio file, etc. The execution content of steps S42 to S44 is the same as the execution content of steps with the same symbols as described in the previous embodiments, and will not be described again here.

Please refer to FIG. 6 , which is a schematic diagram of a usage scenario of a bank transaction system based on Bluetooth communication according to another embodiment of the present invention. As shown in Figure 6, two users using mobile devices 2a and 2b respectively are using the bank transaction system to transmit transaction data, and the remaining three users using mobile devices 2c, 2d and 2e are waiting. The two bank transaction systems in this figure respectively include Bluetooth shielding boxes 10a and 10b, first Bluetooth transceivers 21a and 21b, second Bluetooth transceivers 22a and 22b, and computing devices 30a and 30b. Duplicate connection relationships are omitted here. It should be noted that one of the bank transaction systems further includes a biometric device 40a, which can be used by users whose mobile devices (such as mobile phones) do not support the biometric function. Specifically, the biometric device 40a is a facial recognition device. In other implementations, the biometric device 40a may be a fingerprint recognition device or a voiceprint recognition device.

Please refer to FIG. 7 in conjunction with FIG. 6. FIG. 7 is an operation flow chart of a modified implementation of the bank transaction system based on Bluetooth communication shown in the embodiment of FIG. 6 of the present invention. In this embodiment, the operation flow of the bank transaction system includes step S40, step S41, step S72, step S73, and step S42 to step S44. Step S40 is: the second Bluetooth transceiver receives a connection request from the mobile device located outside the Bluetooth shielding box, that is, the second Bluetooth transceiver 22a and 22b can be connected to the mobile devices 2c, 2d and 2e and receive the connection request. Step S41 is: the computing device generates the original transaction electronic document and transmits it to the mobile device through the second Bluetooth transceiver. That is, the second Bluetooth transceiver 22a and 22b can transmit the corresponding transaction electronic document to the mobile device 2c, 2d and 2e, so that While waiting, the three users can fill in the electronic transaction receipts on their mobile phone banking application (App). Step S72 is: the computing device allocates the mobile device to a first Bluetooth transceiver according to a set of determination parameters. Step S73 is: the computing device generates a predetermined waiting time and transmits it to the mobile device through the second Bluetooth transceiver, wherein steps S72 and S73 are in Sequentially exchangeable or parallel processing. For example, the computing devices 30a and 30b can allocate different mobile devices to different first Bluetooth transceivers 21a and 21b according to the decision parameters. Specifically, the user using the mobile device 2c precedes the user using the mobile device 2d and 2e. The two users are connected to the second Bluetooth transceiver, and the computing device 30a determines that the mobile device 2a completes the transaction before the mobile device 2b, and accordingly the computing device 30a assigns the mobile device 2c to the first Bluetooth transceiver 21a. Further, the computing device 30a can estimate the time required for the mobile device 2a to complete the transaction, and transmit the predetermined waiting time to the mobile device 2c through the second Bluetooth transceiver 22a. That is to say, the computing device can use the time sequence as a decision parameter for the action. device is allocated. The execution content of steps S42 to S44 is the same as the execution content of steps with the same symbols as described in the previous embodiments, and will not be described again here.

In addition, for example, although the mobile device 2d later than the mobile device 2c can be assigned to the first Bluetooth transceiver 21b to be staggered with the mobile device 2c to reduce the waiting time, however, since the mobile device 2d lacks support for biometric identification functions, the calculation The device can still assign the mobile device 2d to the first Bluetooth transceiver 21a, which means that the computing device can assign biometric recognition to the mobile device as a decision parameter, and can also further use the estimated distances of the mobile devices 2a and 2c to complete the transaction. The required time is used as the predetermined waiting time, and is then transmitted to the mobile device 2d through the second Bluetooth transceiver 22a. In addition, on the premise that the signal connection is maintained between the biometric device 40a and the computing device 30a, the computing device 30a can also independently arrange for the user to go to the biometric device 40a to perform biometric operations, and then assign the mobile device to other first Bluetooth transceivers. , this part is not restricted.

In some situations, such as when processing a business that is more complex and requires professional assistance, the computing device can use the business type as a decision parameter to allocate the mobile device, such as the first blueprint. The Bluetooth transceiver 21a may be specifically targeted at account opening related services, and the second Bluetooth transceiver 22a may be specifically targeted at transfer services. Accordingly, the bank can use streamlined manpower to provide system support. For example, bank staff can pay special attention to users who perform transfer services at the first Bluetooth transceiver 21b to prevent fraud-related crimes from occurring. After step S73 (or step S72), the above-mentioned steps S42 to S44 can be performed, which will not be described again.

Please refer to FIG. 8 in conjunction with FIG. 6. FIG. 8 is an operation flow chart of another variation of the implementation of the bank transaction system based on Bluetooth communication shown in the embodiment of FIG. 6 of the present invention. In this embodiment, descriptions of steps S40, S41, S72 and S73 that are the same as those in FIG. 7 will be omitted. This implementation aspect also includes step S84 and step S85. Step S84 is: the computing device determines whether the mobile device has not been connected to the first Bluetooth transceiver when the predetermined waiting time returns to zero. Specifically, when the predetermined waiting time of the mobile device 2c reaches zero, the computing device determines whether the mobile device 2c has not yet been connected to the first Bluetooth transceiver 21a paired with it. If the mobile device 2c is connected to the first Bluetooth transceiver 21a, steps S42 to S44 are executed. If the mobile device 2c is not connected to the first Bluetooth transceiver 21a, the computing device 30a can communicate with the mobile device through the second Bluetooth transceiver 22a. The device 2c sends an urging message, which is step S85.

Please refer to FIG. 9 in conjunction with FIG. 6. FIG. 9 is an operation flow chart of another variation of the implementation of the bank transaction system based on Bluetooth communication shown in the embodiment of FIG. 6 of the present invention. In this embodiment, descriptions of steps S40, S41, S72, S73 and S84 that are the same as those in FIG. 8 will be omitted. This implementation aspect also includes step S95 and step S96. Step S95 is: when the predetermined waiting time is reset to zero and the mobile device has not yet been connected to the first Bluetooth transceiver, the computing device may determine whether the second Bluetooth transceiver cannot be connected to the mobile device. Taking the above example as an example, if the second Bluetooth transceiver 22a can be connected to the mobile device 2c, the above step S85 is executed. Otherwise, the computing device 30a can cancel the allocation of the mobile device to the first Bluetooth transceiver 21a and regenerate the predetermined waiting time for other mobile devices paired to the first Bluetooth transceiver 21a (such as the mobile device 2d), and then assign the mobile device to the first Bluetooth transceiver 22a through the second Bluetooth transceiver 22a. The updated scheduled waiting time is sent to the mobile device 2d, that is, step S96.

With the above structure, the bank transaction system based on Bluetooth communication disclosed in this case can form a data-secure storage space through a Bluetooth shielding box, which is used to allow mobile devices and Bluetooth transceivers to perform secure transmission via Bluetooth in the space. Transaction data transmission, on the one hand, allows users to fill in transaction data using a convenient interface on their mobile phones, and on the other hand, it also ensures the confidentiality of private data during the transaction process, thus improving the inconvenience of traditional written documents and Personal information leakage issues in general online data transmission.
