Radio Frequency IDentification(RFID) is in the limelight of fields of military, delivery and library management as an alternative or barcode system. However, it is restricted within product manufacturing, sales and delivery. In this paper, we apply RFID technology into process, especially packing process management to gauge RFID applicability. To verify beneficial features of RFID, we simulate RFID-adopted packing process. As a result, we demonstrate the effectiveness of a RFID-based Process Improvement In manufacturing process. The results of performance evaluations demonstrate that the proposed RFID-based Process Improvement reduces the labour time, labour cost and material cost. Furthermore, we analyze the validity of RFID-based Process Improvement by RFID cost.

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.

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.

In order to decode the bar code image binarization process is indispensable. The traditional binarization method is a global threshold binarization and local threshold binarization. Global threshold binarization method using a single threshold. In some cases there is a blur, or if the brightness is different from the bar code image. Therefore, binary pattern information is not retained. Local threshold method is binaized pattern information is maintained but processing speed is slow than global threshold binarization. The algorithm for solving this problem, there is modified binary algorithm. In this paper, we proposed hardware IP implemented by Vivado of modified binary algorithm.

This thesis shows embodiment of lock system design for combination of usefulness, convenient of Barcode and cellular phone. This thesis consists of Lock system design using cellular phone and product introduction, including details from formation of barcode scanner to scanner design. When this research is applied to security system a general idea of physical key disappears and it is Possible that cellular phone becomes the center of security and we can expect that cellular phone use for payment will increase due to mutual direction service. After, we should study its application to various practical field and develop high sensitive equipment.

Contents of this paper strengthen security of data by applying encryption algorithm to use cellular phone and settlement by Mobile that is used synchronization method and quotes and prevent damage of bar-code peculation etc.. If divide system step by step to execute this, step that create Mobile bar-code and transmits by individual terminal after encryption, step displaying to individual Mobile terminal, step that above individual Mobile terminal and main server form assimilation and these are consisted of step that quote confirming above information confirmation and motive availability. For the actual example, confirm effectiveness of certification system through simulation.

This paper is presented to study simplification of face image using cubic spline interpolation for a business card with 2D barcode. People often forget business card's owner because business cards don't be included a face picture generally. To solve such problem, many applications have be developed through mobile devices, Internet and so on. But they couldn't caught up with value of existing business card mad by paper. Hence, some methods which can put information on business card using 1D or 2D barcode had suggested. but they couldn't include information like face image or company logo image which have too much data. Therefore, we study the simplification method of face image to encode from a face image to 2D barcode. The simplification method using spline curves defined by feature points which we dotted on face, ears, hair, eyebrows, nose, lips, neck, etc.. on a face area. for experiment, we see real face image and simplified face image made by proposed method after we automatically extract face watch through camera. In experimental results, data of simplified face image was reduced as small as it can be expressed by 2D barcode, and confirmed that it can effectively express features.
