Two-dimensional QR Code has improved greatly the limits on the capacity, size, direction of the one-dimensional bar code. And it has the capacity of compressing and storing the massive amount of data and is widely used in many applications. Recently, the two-dimensional QR Code has been spread rapidly because of introducing the smart phones and increasing the amount of using them. However, there is little documentations about decoding the QR Code in which can store the large amount of information. In this paper, therefore, we present specific processing procedures and algorithms on decoding the two-dimensional QR Code and then make us understand their decoding process by explaining some examples.

In this paper, we proceed with the design and development platform for the development of the optimized applications to take advantage of the sensing techniques of the mobile device, so that this can proactively respond to the user's needs, and can provide access to a range of services. Ubiquitous environment based smart campus is active rather than passive, university will be able to promote the true personal customizable services. Campus tours through augmented reality will support more active university life in conjunction with a variety of services to promote actively utilizing the QR Code(2-dimensional bar code). In addition, we designed to develop a mobile application that can provide such a view and post announcements such as integrated system, through interoperability with existing bachelor's administrative (legacy) system.
