QR codes, a kind of 2-dimensional barcode, is used to encode information such as simple URLs or namecards. QR codes can store much more information than a just barcode can do. Now QR code is very popular service in our ordinary life. These days many companies has used QR codes in the way of home-page link, especially a production explanation, the material instruction of model houses, the services in a library and on-line events, etc. This paper is going to make a study about how to establish a production process management on the basis of QR codes, addedly, about strong points of QR codes and the examples of using it.

As the near field communication technology's application scope tends to expand gradually in the various fields, application of mobile-based NFC(Near Field Communication) is increasing in the various types of technologies. The method which reads the URL address and supports access to the web site of the address if you touch the NFC device in the tag(RFID) that the URL address is stored was applied to the unmanned security system. It proposed the effective plan to manage mobilization security business in the aspects of Integrity, Damage, Real-Time, and Speed through comparison and verification of the method with the existing unmanned security system.

A Smartphone has an ability accessing Internet by URL stored in NFC(Near Field Communication) Tag for storing the information of items, blogs and web pages. Because the system works through the Internet with URL, however, it needs to pay some costs like communication fee and time. If we can store the web page on the tags, we can save the communication overhead. But they have too small memory to store it. In this paper, we introduce the Micro-Webpage technology which can be stored in NFC tag or QR(Quick Response) code. To make a Micro-Webpage, we remove control tags from the web page to leave a user original content. The removed control tags are stored in our smartphone application as a template. The user content is also compressed to a smaller one by an lossless compression algorithm. When a tag is read, the stored content is decompressed and, it is combined with the template to make the original web page. We have implemented a prototype of Micro-Webpage system on Android platform and confirmed that the prototype has reasonable performance improvements in saving memory and loading web page time.
