QR碼 (Quick Response Code) 是近年來新興的熱門技術,QR碼除了做為行動支付、數位內容下載、網址快速連結之外還可以應用在很多其他的應用上。智慧型裝置則是近年來越來越普及,幾乎已達人手一支手機的情況。本論文我們利用QR碼提出一套點名系統,此系統利於迅速的回覆相較於傳統的點名方式。藉由使用智慧型手機,學生們可同在少於10秒的時間同時完成點名的動作。在增加系統安全性上,我們使用動態隨時間變化的QR碼和所有訊息在網頁伺服器與手機傳送的過程中加以加密保護。此外學生們的出席紀錄會自動儲存在Google試算表中。教師和學生們可以從網頁中隨時隨地的看到這些紀錄。
In recent years, Quick Response (QR) Code is an emerging and popular technology. QR Codes has successfully applied in mobile payment services, digital content download, website quick links, and many other applications. On the other hand, smart devices are becoming increasingly popular in recent years, and almost every student has one in hand. In this thesis, we propose a smart roll call system using QR code. The system has the advantage of rapid response when compared to traditional roll call methods. By using smart phones, the roll call for all the students of a class can be completed in less than ten seconds. To increase the security of the system, we use time-varying dynamic QR codes, and all messages exchanged between the web server and smart phones are encrypted. In addition, the attendance records are automatically stored to a Google spreadsheet. The teacher and students can use these records through a web service at any time and any place later.
