Japan has been developing and integrating such technology into their culture for some time, yet no single comprehensive framework has emerged. Based upon the review of 24 empirical studies on mobile payments, we propose an integrated model with eleven constructs for mobile payment adoption. Using this proposed framework, we present the case of the Suica/Pasmo mobile payment system in Japan. mobile phone mobile wallet application, and then pay 1.

According to a survey conducted by the Bank of Japan Yasuoka (2009) reports that the decrease by in April 2010, when asked about the meaning of 0.04% in the circulation of money announced by the electronic payments, more people think of payment Bank of Japan in 2006, the first time since 1971, can be systems using value-stored IC cards or mobile phones attributed in part to the increase usage of electronic that they wave in front of dedicated card readers (Bank money. However, the high penetration rate of mobile of Japan, 2009). Some public transportation operators phones and the existence of a majority of mobile in the Tokyo area offer parents a service to monitor phones capable of making mobile payments (ITIF, their children’s movements on the transportation 2009) cannot alone explain the success of mobile network, based on their use of their IC-based payments. The United States enjoys a similar transportation pass. Indeed, Japanese children usually penetration rate of mobile phones, but that country start going to school on their own from the age of six offers mobile payment systems on a trial basis only, and a service such as Tokyu’s Kids Security Service, whereas Japan boasts more than 90 million active cards enables parents to receive email notifications to their or mobile phones engaging in mobile payments for mobile phone every time their children go through a Suica/Pasmo and Edy (Suica, 2009a; Suica, 2009b; ticket gate and use their IC pass (Tokyu Security, Suica, 2010, Edy, 2009; Edy, 2010). 2010). Odakyu Railways offers a similar service that Although the literature abounds with various caters to the children that use Odakyu Lines with models exploring the determining factors of mobile PASMO (Odakyu Anshin Goopas IC, 2007). payment system adoption, no single framework has yet According to Mediba (2010), in a recent survey of emerged on those critical constructs from the 900 respondents, 92.9% were aware of their mobile consumer’s perspective. Therefore, through a thorough phone’s capability to make electronic payments. And review of existing studies, this paper aims at proposing 23% actually said they used their mobile phone as a comprehensive model of mobile payment adoption. electronic wallet also known as Osaifu–Keitai.

Several other constructs deemed in March 2004, in order to “capitalize on the potential redundant, such as perceived performance expectancy of Suica as a means of settling transactions for small and perceived credibility, or unsupported in previous sums” (JR East, 2009, p. 36).

The reputation, image and service quality of viable competing alternative available in the market place One reason for the success of Suica has to do with (Bendapudi and Berry, 1997; Jones et al., 2000) the pricing of commuter travel in Japan. Before Suica, when traveling from station A to B, commuters had to refer to a detailed route map to work out the fares to 3.
