Today, using RFID(Radio Frequency Identification) card is extended in diversity as medical treatment, circulation market, military affairs, manufacture, security, etc. The RFID technology is an automatic identification method, relying on storing and remotely retrieving data for the purpose of identification using radio waves. This advantage of the RFID will be as a replacement for traditional Barcoding. Besides, book-lending system and attendance management system become the center of educational institution in interest. This paper presents a attendance management system using the RFID card which provides directly information of attendance for professors with mobile and students with web. Also, the students only have ID card that embed RFID tag which is recognized attendance through DB that storages to is received a information of student from RFID card Reader. And it is possible management or report for attendance and time table not only for professors by management program but also for students by web program.

A distance learning is diffusing rapidly in society. It is more difficult to confirm a learner's identity and learning processing in a distance learning. Distance learning has a checking attendance system because a teacher and student do not meet face to face. There are some checking attendance systems such as login check, SMS authenticating system, unexpected quiz, and so on. However, existing checking attendance system has some problems to check learner's attendance in a whole lesson. Therefore, this study designed and developed learner's attendance system based on PC camera's shot of certification in a whole lesson. This attendance checking system can judge real attendance of learners in a distance learning and distance evaluation. The system is expected to make trust of a distance learning higher.

There are management and price problems that have been caused by requirement of RFID reader, Fingerprint Identification System and Clicker for the construct of automatic attendance system to check the students' attendance accurately and quickly. Therefore, in the thesis, we developed smartphone based attendance check system by utilizing Wi-Fi and the smartphones that has been already built without using additional equipments and establishing construction of system additionally. It recognizes date, time, location and the seat number in classroom if a student logs the attendance chocking application in and it also allows students to get lecture feedback and check attendance by taking quizzes and questionnaires that are related to the lecture. As a result, by applying the attendance check system, instructors state that it is convenient since the app allows instructors to communicate with students though the quizzes and questionnaires. Especially, the instructors state that it is convenient because the results of the quizzes, questionnaires and attendance can be downloaded it the from of Excel files.

출석체크를 자동으로 하는 시스템으로 QR 코드나 NFC 등의 전자 태그기반 방식들이 있으나 태깅을 수동으로 해야 하는 불편함과 함께 태그의 물리적 파손 문제 등의 단점이 그 확산에 제한 사항으로 작용하고 있다. 본 논문에서는, 태그 기반 대신 Bluetooth Low Energy(BLE) 비콘 신호를 학생들의 스마트폰으로 수신하여 위치와 시간을 확인함으로 출석을 자동으로 체크하는 경제적이고 안정적인 출결 시스템을 제안한다. 나아가, 시스템 초기 및 유지 비용을 구성하는 요인들을 분석하고, 시스템의 안정적 운영을 보장하는 제한조건 하에서 BLE 비콘의 설치 및 운영의 경제성을 높이기 위한 추가적 변인들을 열거하고 변인들 간의 trade-off를 고려하여 시스템을 설계해야 함을 보였다.

As unmanned processing systems emerged socially due to the rapid development of modern society, a face recognition attendance management system using Raspberry Pi 4 was studied and conceived to automatically analyze and process images and produce meaningful results using OpenCV. Based on Raspberry Pi 4, the software is designed with Python 3 and consists of technologies such as OpenCV, Haarcascade, Kakao API, and Google Drive, which are open sources, and can communicate with users in real time through Kakao API for face registration and face recognition.

In this paper, we propose electronic attendance checking system using a bluetooth beacon in the absence of Wi-Fi or cellular networks. The proposed electronic attendance checking system uses a polling scheme where the administrator sends a request message and the attendees response using a beacon packet. Existing electronic attendance checking system requires a centralized server but the proposed method can check attendance without any external networks.

WHO declared a global pandemic on March 11th for Corona 19. However, there is a situation where you have to go to building for face-to-face education or seminars for economic and social activities. The first check method of COVID-19 infection is to measure body temperature, so the primary entrance and exit is blocked for near-field body temperature measurement. However, since it is troublesome to check directly, thermal camera is installed at the entrance of the building, and body temperature is measured indirectly using the infrared camera to control access. In case of middle and high schools, universities, and lifelong education center, we need a system that is possible to interoperate with attendance checks and automatically recognizes whether to wear masks and can authenticate students. We proposed the system that is to confirm whether to wear a mask with a camera that is embedded in a smart mirror, and that authenticates the user through voice recognition of the user who wants to enter the building by using voice recognition technology and determines whether to enter them or not. The proposed system can check attendance if it is linked with near-field temperature measurement and attendance check APP of student's smart phone.

The electronic attendance management system is being introduced and operated on a pilot basis by some universities and educational institutions. However, most of the related systems have installed and operated the existing barcode and magnetic card systems. Classroom attendance is managed by introducing RF cards, but it causes problems such as recognition distance (less than 5cm) and the need for a check process in which students have to read the card each time with a reader for attendance. Also, it is not possible to respond in real time to the situation of midterm (early leave, absence from the second lecture time, etc.) because it is used in the lecture time of one subject with the record checked once. In order to solve these problems, the various mobile attendance systems proposed to solve these problems are also unable to fundamentally solve problems such as interim attendance and proxy attendance because they check attendance using only the application of a smartphone. In this paper, we use geofencing technology, which is a positioning-based technology that detects the entry and exit of people, objects, etc. in areas separated by virtual boundaries. The proposed system solves the problem of intermediate attendance and alternate attendance by setting the student to automatically record the access record when entering and leaving the classroom set as a geofence with a smartphone. In addition, it also provides a function to prevent unintentional mistakes that occur through the smartphone by limiting some of the functions of the smartphone such as silence, vibration, and Internet use when entering the classroom.

Due to the lack of attendance management system, the training conducted by each existing institution was handwritten at the site and managed in writing about the attendance of participants. It not only takes a lot of manpower and time to store and search, but also has a lot of difficulty in storing. In this paper, we design and implement an integrated smart attendance management system using barcodes. Through this, the attendance system of training applicants is developed, security related to attendance is strengthened, and training attendance data is computerized and collected. In addition, standards for necessary data are selected so that each institution can efficiently manage and utilize training information data. The proposed system can add various institutions in a single construction, making it easy to expand institutional management and can expect additional cost reduction effects. In addition, it is expected that the quality of education will be improved by increasing the convenience of training managers who use the management system provided and controlling/managing attendance data of users.

본 논문에서는 지능적으로 폴링과 랜덤접속모드를 사용하는 RFID 충돌방지 기법을 제안하고자 한다. 본 논문에서 제안하고자 하는 충돌방지 알고리즘은 태그의 교체율이 크지 않을 경우, 먼저 이전 인식과정에서 성공적으로 식별한 태그들에 대한 고유정보를 기억한 뒤 다음 인식 세션에서 그 고유 정보를 활용하여 출석을 부르는 것처럼 경쟁 없이 태그들을 호출하여 빠르게 식별한다. 이전 세션(session)에 비하여 많은 수의 태그가 교체되었으면 인식률이 저하될 수 있다. 이 경우에는 랜덤 접속모드로 전환하여 나머지 태그들을 읽어 낸다. 본 논문에서 제안하는 것처럼 인식이력을 활용한 모드와 랜덤 접속 모드를 적절히 조합하여 운용하면 태그 인식 시간을 단축할 수 있으며, 특히, 주기적으로 개체의 존재 유무를 확인하는 응용의 경우에 우수한 성능 향상을 얻을 수 있다.
