The processor 22 may extract user information matching the extracted information. For example, in a user registration process, user information stored in matching with corresponding information may be extracted.

Meanwhile, the processor 22 may extract user information included in the sound wave signal received from the user terminal 200 . The sound wave signal may include user information, and the processor 22 may extract user information from the received sound wave signal.

The processor 22 may verify the user by comparing user information extracted from the received sound wave signal with user information extracted from pre-stored information. That is, the processor 22 may compare whether the user information included in the sound wave signal and the user information stored matched to the sound wave signal are the same. Accordingly, it is possible to verify the user by checking whether the user terminal 200 that has transmitted the sound wave signal is the user terminal 200 of the corresponding user. Specifically, the user may be verified through a process of extracting user information by decoding a sound wave signal and a double verification process of comparing a sound wave signal pre-allocated with respect to a corresponding user and a received sound wave signal.

The processor 22 may match and store the acquired user information and the time at which the sound wave signal was received. According to an embodiment of the present invention, since the purpose is to collect information of a user visiting a space and the time the user visits, the processor 22 matches and stores the acquired user information and the time the sound wave signal is received, thereby achieving the purpose. can be achieved

In one embodiment, the processor 22 may transmit access authentication or not to the user terminal 200 based on user information. Whether or not access is authenticated may be for notifying the user that check-in has been performed normally. The processor 22 may transmit access authentication to the mobile phone number included in the acquired user information.

The processor 22 may transmit authentication or non-authentication to the user terminal 200 through a text message or a messenger application, or may transmit authentication or non-authentication to the user terminal 200 through an app push of a connected application. Also, the processor 22 may provide a matching page corresponding to a space to the user terminal 200 .

In various embodiments, the processor 22 may obtain information about a space where the user terminal 200 is located, and provide a corresponding matching page to the user terminal 200 based on the acquired space information. At this time, the processor 22 extracts previously stored space information based on the obtained space information, and the extracted space information may include characteristics, types, and requests of the space.

That is, the processor 22 may transmit a matching page corresponding to a corresponding space to the user terminal 200 based on the extracted space information. On the other hand, if the obtained space information is not previously stored, the processor 22 requests input of space information from a terminal installed in the space (eg, the check-in terminal 300) or the user terminal 200, or , POS device details, Internet maps, etc., collect information about the corresponding space, and based on the collected information, the type of the corresponding space can be determined. The processor 22 may transmit a matching page corresponding to the determined space type to the user terminal 200 .

In various embodiments, the processor 22 may generate a sound wave signal for verification. The sound wave signal for verification may be used to verify a user who has completed check-in and to transmit a matching page to the corresponding user. At this time, the sound wave signal for verification may be deleted after verification is completed for one-time use, but is not limited thereto.

In various embodiments, the check-in terminal 300 may output a sound wave signal for verification. Here, the sound wave signal for verification is also a sound in a high frequency band, and may be a sound wave in an inaudible region that people cannot hear.

The user terminal 200 may receive a sound wave signal for verification. The sound wave signal for verification may be transmitted through spreading, and a receiving terminal may not be separately set.

Accordingly, the verification sound wave signal output from the check-in terminal 300 may be received by all of the plurality of user terminals within the space. At this time, the plurality of user terminals may be in a state in which an application is running, and the application may be activated when a sound wave signal for verification is received.

The user terminal 200 may extract information included in the received sound wave signal for verification. User information may be included in the sound wave signal for verification, and in this case, the user terminal 200 may extract user information included in the sound wave signal for verification.

The user terminal 200 may compare user information extracted from the sound wave signal for verification with user information stored in an application.

The sound wave signal for verification may be received from a plurality of user terminals, but on the other hand, the sound wave signal for verification may be generated to verify a user who has completed authentication and to provide a matching page to the verified user. Accordingly, the user terminal 200 may compare user information included in the sound wave signal for verification with user information stored in the application, and transmit the comparison result to the check-in terminal 300 or the server 100 .

For example, when another user terminal receives a sound wave signal for verification, user information included in the corresponding sound wave signal for verification may be different from user information stored in an application accessed from another user terminal.

The server 100 or the check-in terminal 300 transmits a matching page to the user terminal 200 in which the user information included in the sound wave signal for verification of the comparison result matches the user information stored in the application, and separately stores the comparison result. In addition, information indicating that verification has been completed for the previously stored corresponding user information may be stored together.

Meanwhile, when the user information extracted from the sound wave signal for verification is not the same as the user information stored in the application, the user terminal 200 may deactivate the application.

Through this, when a check-in for a space occurs, information on the user who performed the check-in is stored and a sound wave signal for verification is output through the check-in terminal, so that the user terminal is used for verification when the terminal of the corresponding user is actually located in the space. It is possible to prevent misuse or error of sound wave communication technology by accessing the matching page of the space after receiving the sound wave signal.

In one embodiment, various methods may be applied to prevent the recording and use of another person's sound wave signal. In one embodiment, information for verifying the sound wave signal as well as user information may be stored in the sound wave signal. For example, the sound wave signal may include, in addition to user information, information on a time when the corresponding sound wave signal was generated or OTP information generated at the corresponding time, but is not limited thereto. The check-in terminal 300 not only obtains user information included in the received sound wave signal, but also performs verification on the user and verification on the time when the corresponding sound wave signal was generated through OTP information stored therewith. .

According to an embodiment, when a matching page of a space is accessed through the user terminal 200 that has received the sound wave signal for verification, and the user terminal 200 receives a signal indicating that verification using the sound wave signal for verification has been completed, It is possible to confirm that the space entry record of the corresponding user is true, and to store the confirmation fact.

That is, although it is possible to confirm the user terminal 200's access to a space only by receiving a sound wave signal from the user terminal 200, the check-in terminal 300 may output a sound wave signal for verification for additional verification. In addition, the user terminal 200 receiving this compares the user information stored in the user terminal 200 with the user information included in the sound wave signal for verification, and transmits information indicating that verification has been completed to the check-in terminal 300 or the server 100. ) can be passed on. When verification completion information is obtained, the check-in terminal 300 or the server 100 may store the entry/exit of the corresponding user.

In another embodiment, the check-in terminal 300 may output a sound wave signal for verification including information about a user who has checked in to the space at a predetermined time interval (eg, 30 minutes). The user terminal 200 receives the sound wave signal for verification, and when it matches the user information stored in the user terminal 200, transmits a signal indicating reception to the check-in terminal 300 or to the server 100 through the network. can inform When the check-in terminal 300 or the server 100 fails to obtain a signal from the user terminal 200, it may be determined that the user has left the space. Through this, information on not only the entry time of the user but also how long the user stayed in the space can be obtained.

In another embodiment, the check-in terminal 300 is a sound wave containing information that causes the user terminal 200 that has received the sound wave signal to output a sound wave signal including user information at every predetermined time interval (eg, 30 minutes). signal can be output. Through this, it is possible to obtain user information on all user terminals located in the space, whether or not there is a user who has not checked in at the time of admission and information about the user, as well as a user who has checked in. Information on how long stays in the corresponding space can also be acquired.

In this case, in order to minimize collisions that may occur due to simultaneous output of sound wave signals by a plurality of user terminals that have received sound wave signals, sound wave signal output timings of possible user terminals are distributed even if a specific user terminal is not specified. Information that can be done can be stored.

For example, in the sound wave signal, a random number is generated by using device information (e.g., MAC address, IMEI, phone number, etc.) of the receiving user terminal as a seed, or a specific value included in the device information (e.g., the last digit After setting the delay time based on ), information for outputting the sound wave signal after the corresponding delay time may be included.

Alternatively, when a sound wave signal is received from the check-in terminal, the application of the user terminal may be set to output a sound wave signal after setting a delay time using a corresponding method.

For example, when the end digit of a phone number of a user terminal is 7, the user terminal may receive a sound wave signal and output a sound wave signal 7 seconds later, but is not limited thereto.

In various embodiments, when the matching page is an order page, the user may request an order through the order page provided to the user terminal 200 . When an order request is received from the user terminal 200 , the server 100 may provide a payment page for the order request to the user terminal 200 . When payment for the requested order is completed, the server 100 may provide order details to the store terminal. Accordingly, the store may check the order, prepare food for the order, and provide it to the customer. In addition, it is possible to obtain information on whether to eat at the store or to take a meal through the order page of the user terminal 200, and store the corresponding information together with user information and entrance time.

According to this, a customer can sit down and place an order through the user terminal 200, thereby reducing the hassle of queuing or waiting for an order, and the store can reduce the number of manpower to take orders, thereby improving store operation. You can cut costs.

In addition, by completing an order and payment through the user terminal 200, contact with other people can be minimized during an epidemic.

As described above, according to an embodiment of the present invention, when a user enters a space, sound waves output from a user terminal are received to check in the user's entry time, and a matching page is provided for users who have completed check-in to provide convenience to the user. A method of providing access check-in and matching pages using the provided sound waves can be realized.
