China, the second-largest economy in the world, has been an eye-catching destination for several foreigners who wish to live and study there. As they are beneficiaries of the Chinese advanced digital payment system, subjective security in using the mobile payment system and the subsequent change in their consumption intention has been a behavioral concern that perplexes scholars. Using SEM, we integrated the technology acceptance model (TAM) with two Subjective security Constructs (perceived confidentiality and perceived trustworthiness) to determine their impact on the system's adoption intention. At the same time, we evaluated the change in consumption intention using one factor (post-adoption consumption intention). A self-administered questionnaire based on prior literature was developed, and a total of samples of 260 foreigners who are extensive users of mobile payment were engaged. The study revealed that once again, TAM's model constructs (perceived usefulness and perceived ease of use) are dominant factors of adoption intention. While one of the subjective security constructs (perceived trustworthiness) was found to be a significant decisive determinant factor, the other one (perceive confidentiality) was found to be a negative but insignificant factor in mobile payment adoption intention among the expatriates. Moreover, this study provides insight into the digital payment system and its impact on influencing consumption intention beyond adoption. Key words: Technology acceptance model (TAM), subjective security, consumption behavior, expatriates.
