Design and Implementation of Sign-in System Based on Bluetooth Technology

Abstract

Because the traditional way of signing in on class is always writing on the paper or calling one’s name, complicated and time-consuming, to update the way is a hot topic in the present, and many new technologies continue to gush, such as registration card scheme, face recognition scheme, fingerprint identification scheme. However, they always meet some challenge when applied to actual life especially in the class because they are usually expensive, not convenient enough, and most importantly they lack humanization. This paper designed a kind of automatic sign-in system based on Bluetooth technology, implementing automatic registration with the use of Bluetooth on mobile phone. As long as the students have mobile phones and take them to the class, the teacher can do roll call automatically, which is convenient, zero cost and much more people-oriented. This paper introduces the design of automatic sign-in system using Bluetooth technology, and compares it with other methods to prove that this is an innovative way.
