The purpose of this study is to examine whether switching intention of Korean simple payment service can be explained by using more parsimonious model than the PPM model. Specifically, this study aims to explain the switching intention of simple payment service users with a two-factor model (Herzberg) called the motivation-hygiene theory. The Technology Acceptance Model (TAM) is also a simpler model than the PPM model. However, the technology acceptance model fits well when applied to the context in which new products or services are accepted. Considering that the simple payment service has been active when mobile phone authentication was allowed for consumer convenience, it is difficult to consider simple payment service as a new technology. In summary, this study attempts to explain the switching intention of simple payment service by using the motivation-hygiene model. As a result of the empirical analysis, it was found that both motivation factors(brand image, reliability, convenience) and hygiene factors(versatility, security, stability) affects significantly the switching intention.
