The system to manage attendance comprises: a smart device for a manager to connect to a Wi-Fi to confirm whether a smart device for a member is located within a predetermined range from the smart device for the manager; the smart device for the member to confirm whether an AP (access point) of the smart device for the manager is detected by scanning the Wi-Fi in a predetermined period and to transmit a Wi-Fi scanning result to a server by connecting to the server; and a server to receive the Wi-Fi scanning result from the smart device for the member, to notify an attendance approval message to the smart device for the member when a manager AP of a lecture, which the member will attend, exists in the Wi-Fi scanning result, and to notify an attendance non-approval message to the smart device for the member when the manager AP does not exist in the Wi-Fi scanning result or when the manager AP of the lecture, which the member will attend, is not matched. The system may manage the attendance of a user without restrictions of the number of simultaneous access of an AP within a range allowed by a coverage of a signal strength. |
