In other words, the electronic attendance management system of the present invention, the attendance management server (3), the attendant (or professor in charge) for attendance and personal authentication information (including fingerprint, iris, finger vein, ECG and PPG) of attendance You must register. That is, the students (or professors) and the workers for attendance management access the attendance management menu of the time and attendance management server 3, and then, through the biometric information reader 1, their personal authentication information such as fingerprint, iris, and designation. Mac, ECG and PPG information is uploaded and accordingly the time and attendance management server 3 registers the personal authentication information in the DB 2. In addition, the time and attendance management server 3 interoperates with the attendance management terminal 4 interspersed and installed through a wired / wireless network, and requests the authentication of biometric information of individual workers or students from any attendance management terminal 4. Always check whether a signal is received.

On the other hand, if the students (or professors) and the workers are going to the building or classroom for attendance during the above process, they are going to execute attendance authentication procedure through their registered smart device (5) or attendance management terminal (4). In this case, the attendance management terminal 4 executes the attendance authentication procedure according to the set priority mode.

For example, when the attendance management terminal 4 is set to the third priority mode from the time and attendance management server (3), the living body provided to itself regardless of the authentication request signal of the registered smart device (5) of the worker or lecturer Authentication is performed only through the information recognizer (1).

In this case, when the worker or the student's student approaches the classroom or building for attendance, the worker or the student's student touches the display unit 13 of the attendance management terminal 4 installed on the outer wall of the door 6 of the classroom or the building. The screen method is pressed or the finger 16 is in close contact with the biometric information reader 1 and attempts to recognize the finger vein information 8 (at this time, in another embodiment of the biometric information reader 1). , Biometric information can be detected by a selected configuration from a fingerprint reader, a iris reader, an electrocardiogram sensor for sensing an electrocardiogram, and a photoplethysmography for obtaining PPG (volume pulse wave) information).

Then, the attendance management terminal 4 is secondly authenticated in the same manner as the third priority mode through the biometric information reader 1 for the individual worker or the student who is first authenticated by the smart device 5. Then, the secondary authentication information is transmitted to the time and attendance management server (3) to update attendance management information of the worker or student.

Here, if the first priority is set in the attendance management terminal 4 during the authentication process, the attendance processing is performed immediately by the first authentication of the smart device 5 immediately without the secondary authentication processing of the attendance management terminal 4. do.

That is, during the certification process, if the lecture time or the start time of work is imminent but the attendance procedure cannot be performed normally due to the large number of lecturers or workers, the emergency processing signal is sent from the smart device 5 of the professor or manager in charge. When received by attendance management terminal (4) or time and attendance management server (3), attendance management server (3) is the first attendance management signal of the smart device (5) without the second authentication to the emergency mode to the attendance management terminal (4) Only the same authentication procedure as the first priority mode is executed. That is, when the lecture student or worker flocked to the lecture time or the start time of work, and the emergency mode is set, the lecture student or worker only needs to perform the first authentication through his smart device (5). The attendance management authentication app of the device 5 transmits the currently authenticated primary authentication information to the attendance management terminal 4 installed in the classroom or building entrance to be currently entered in the Bluetooth method. Then, the attendance management terminal 4 immediately performs the first authentication information of the individual worker or lecturer who is first authenticated by the smart device 5 in the same manner as the third priority mode, and then the authentication. The authentication information is transmitted to the time and attendance management server (3) to update the attendance management information of the worker or student.

Meanwhile, another embodiment of the biometric information recognizer 1 provided in the attendance management terminal 4 used during the biometric authentication process may be used, and the structure thereof includes the LED light source 15 and the reflector member that have been installed in a plurality of sidewalls.
