A study on development of OTIP system using QR code based on smartphone

Abstract

Today, as the supply of smart phones becomes active and a variety of functions of smart phones and services based on internet is utilized, a wide range of applications are being developed and deployed. Despite the rapid growth of smart phones and the application market, the attendance book which is currently being used is still in its primitive forms. Previously developed automatic attendance or absence check system requires additional equipments such as RFID reader and fingerprint reader, with higher deployment costs and has problems of management such as mechanical failure and dishonest attendance. In this paper, an automatic attendance check system based on smart phones utilizing the QR code for recognizing the code using the built-in camera function of smart phones and accessing the information included in the recognized code in real-time basis is proposed. The proposed system, by utilizing the built-in camera function of smart phones, can reduce the initial deployment costs because it does not require additional equipments when building the system and has partially solved the problems of dishonest attendance and improved the recognition rate.
