That is, when the received subscriber information and the read out authentication information are the same, an authentication success signal is transmitted to the portable terminal 100, and when the received subscriber information and the read out authentication information are not the same, the portable terminal 100 is sent to the portable terminal 100. Send an authentication failure signal.

Next, a user who has successfully authenticated a subscriber performs shooting of a predetermined identification image at a specific location by using each portable terminal. Here, the predetermined identification image photographed by the portable terminal may be the above-described bar code or QR code. In this case, a specific check-in position is allocated to each of the identification images. That is, if the location assigned to the QR code 1 is the B point of the A coffee shop with latitude X and longitude Y, the check-in is performed only when the user photographs and transmits the QR code 1 from the B coffee shop of the A coffee shop. will be.

When the mission is performed in the portable terminal 100 as described above, the portable terminal 100 transmits a check-in authentication request signal to the check-in server 200 through the communication network 300. In this case, the portable terminal 100 may transmit its location information acquired from the location sensor to the check-in server 200 before or simultaneously with the transmission of the check-in authentication request signal.

In addition, when the check-in server 200 receives the check-in authentication request signal transmitted from the portable terminals 100, the check-in server 200 determines whether the check-in is performed in the designated manner at the designated specific location.

That is, the portable terminal 100 recognizes the predetermined identification image transmitted from the portable terminal 100, the location information assigned to the predetermined identification image stored in the check-in database 213, and the portable terminal actually transmitted by the portable terminal 100. (100) It is determined whether or not their location information matches, and it is determined whether the check-in is performed correctly.

In this case, various methods may be used to determine whether the location information allocated to the transmitted identification image and the location information of the portable terminal 100 are identical. For example, whether the current location of the portable terminal 100 is within a predetermined latitude / longitude assigned to the transmitted identification image may determine whether the check-in authentication is performed. Alternatively, when the current location of the portable terminal 100 is within a predetermined distance from a predetermined latitude / longitude assigned to the identification image, the check-in may be authenticated.

Alternatively, the check-in authentication may be determined based on whether the current location of the portable terminal 100 belongs to an area generated through the list of specific latitude / longitude points. Furthermore, when the current location of the portable terminal 100 belongs to a predetermined black list, it may be determined that check-in has failed.

As such, after authenticating whether or not to perform the check-in, the check-in server 200 may update the check-in date and time, check-in number, check-in point, and the like at each check-in place for each user who has successfully checked-in.

When the check-in process is completed in the check-in server 200 as described above, the check-in performance is transmitted to each portable terminal. That is, the result of the check-in is displayed on each of the portable terminals 100 to check whether the check-in is successful and the check-in point obtained by the user.
