As most of the recent smart devices have NFC function the NFC mobile coupon will become one of the pervasive NFC applications. We need the secure NFC coupon protocols to issue and use NFC mobile coupon. In this paper, we analyze the security of the previous protocols and point out the problems of security. As the result of analysis, Premium M-coupon Protocol proposed by A. Alshehri and S. Schneider is the most secure but has unnecessary operations. We propose the Modified Premium M-coupon Protocol-1 with the unnecessary operations removed and show this protocol is secure by security analysis. Most of NFC mobile coupon protocols use the cryptography with the shared secret keys. We propose the Modified Premium M-coupon Protocol-2 without the shared secret keys and show this protocol is secure by security analysis.

We propose a mobile coupon strategy designed to increase the effect of push notifications on redemption. The proposed strategy recommends that firms deliver mobile coupons with distant expiration dates and remind them through push notifications framed negatively once these expiration dates become imminent, rather than frequently sending coupons with near expiration dates. We test the effectiveness of the proposed strategy using data collected through a randomized field experiment. The findings indicate that push notifications enhance coupon redemption rates for coupons that are held longer by customers than those that are recently received. Additionally, we found that sending negatively framed push notification messages to remind customers of imminent coupon expiration dates further resulted in higher coupon redemption rates. The findings can be employed to offer useful guidance on how to effectively design mobile coupons for achieving higher redemption rates.

This study examined the effects of characteristics of mobile coupon on the user's perceived usefulness and intention of using mobile coupon in order to suggest directions to enhances marketing strategies for foodservice company. The research model for this study was designed based on the hypothesis that the characteristics of mobile coupon influenced both the user's perceived usefulness and purchase intention. Based on total 227 customers obtained from the empirical research, this study reviewed validity, reliability and fitness of research model. Major findings of empirical analysis could be summarise as follow. First, among the characteristics of mobile coupon, the easiness of acquisition and the economic value of the mobile coupon had an influence on the mobile coupon user's perceived usefulness. Second, the easiness of acquisition and the economic value of the mobile coupon had an influence on the intention of using mobile coupon. Third, the mobile coupon user's perceived usefulness had an influence on the intention of using mobile coupon.

Purpose: The purpose of this research is to develop a model tat explains the motivation of mobile coupon gift intention in mobile instant messenger service. Methods: This study utilized Structural Equation Model to clarify factors those influence mobile coupon gift intention under mobile messenger environment. Results: The research model in this study is verified with two hundreds sample data. This study found that mobile coupon gift-givers's giving intention is influenced by experimental and obligated motivation, price utility, social value of gift-giving, and perceived ease of use of the technology. Conclusion: This study verified five factors those influence to mobile coupon gift-giving intention. Although this study initially suggests and verify gift-giving intention model, we expect further research that related to other factors affecting the intention and other recent technology factors such as personal innovation and others.

This study deals with the influencing factors for satisfaction of mobile coupon service. Thus researcher examined a structural equation modeling methodology of the path within word of mouth, satisfaction, and other exogenous variables (economic value, trust, joyfulness, innovativeness). As a result of this study, mobile coupon users understand the characteristics of basic coupon concept, and First, it was confirmed that the economic value, innovativeness affected user's trust for coupon service and joyfulness for using coupon. Second, it was confirmed that trust and joyfulness affected user's satisfaction and word of mouth activities. Moreover, this paper's contribution point is the proposes of the one of the post adoption model with the quantitative study of the industrial development stages of current various mobile coupon application.

Since nowadays mobile phone messages are flourishing, the application of electronic coupon (e-coupon) will become a trend for mobile users. E-coupon for mobile commerce can provide mobility for users and distribution flexibility for issuers. In this paper, we propose a mobile e-coupon system that just applies some simple cryptographic techniques, such as one-way hash function and XOR operation. In our system, the customer can control the number of issued e-coupons and the issuer can prevent them from double-redeeming. The customer does not need to perform any exponential computation in redeeming and transferring the coupons. Our scheme uses one-way hash chains for preventing from double-spending.

Since a smart phone has been popular, 91% of the internet users are utilizing the technology in all places for chatting and messenger which overtake share of voice and visual call utilization. The phenomenon is remarkable to young generations between teenager and thirties, which leads to mobile messenger shopping such as mobile digital voucher and coupon buy. In this research, we clarify whether traditional gift-giving motivations works on digital coupon gift-giving, and two technology acceptance model factors: perceived usefulness and ease of use affects between motivations and intention to gift-giving. The result shows three traditional gift-giving motivations: experiential, obligated and practical attitude affects intention to digital mobile coupon gift-giving and ease of use of the digital mobile coupon works parameter of the relation rather than usefulness. In other words, gift-giving purpose digital coupon users give a gift with traditional gift-giving motivation but has the stronger intetnion to gift-giving by technology ease of use.

Recently, coupons are distributed in various ways such as paper, Internet, and mobile phone, with the development of the information and communications technology. Coupon users benefit from the use of these coupons. For example, they can get a discount for the product that they wanted to buy and can be offered additional services. However, paper and Internet coupons have a risk of loss since users have to cut them out and keep them separately. Mobile coupons also don't provide users with user convenience, because coupon users first look for coupon data from their mobile phone and show it to the counterperson. To solve these problems, this study proposes a NFC-based mobile coupon system under which we can use coupon data only with mobile device access.

Purpose of the study is to explore the effect of the types of mobile coupons(text- vs. image-focused coupons; free-gift vs. discount coupons) on characteristic perception of mobile coupons, and the causal relationships among characteristic perception, attitude, and use intention of mobile coupons. A total of 140 university students participated in experiments with questionnaires including one of the four stimuli. Important findings are as follows. First, image-focused mobile coupons generated more enjoyment than did text-focused coupons. However, the text/image-focused coupons were not different in perception of informativeness and credibility of mobile coupons. Second, enjoyment perception was significantly increased when image-focused contents were combined with discount coupons whereas enjoyment perception was decreased when text-focused contents were combined with free-gift coupons. This interaction effect reflects that the level of enjoyment of consumers can be changed in terms of the combination of the value-provision types of coupons and the text-image focused contents. Third, it was found that consumer perception of coupon characteristics formed attitudes toward mobile coupons, and use intention of mobile coupons was determined by attitudes toward mobile coupons. Study findings may fill the void of research investigating the effect of text-image contents and the types of coupons on consumer reponses toward mobile coupons. Mobile coupons have limited quantity of information within a small size of mobile phone screen, therefore, the results were not consistent with prior research tested with mobile advertisements indicating the effect of text-image contents on perception of informativeness and credibility.
