Abstract

Security is identified as a major barrier for consumers in adopting mobile payment. Although existing literature has incorporated security into the Technology Acceptance Model (TAM), the Unified Theory of Acceptance, and the Use of Technology (UTAUT) and it has investigated the way in which security affects consumers’ acceptance of mobile payment, security is a factor only in diverse research models. Studies of mobile payment that focus on security are not available. Additionally, previous studies of mobile payment are based on Direct Carrier Billing- (DCB)-based mobile payment or Near Field Communication- (NFC)-based mobile payment. The results regarding security might not be applicable to Quick Response (QR) code-based mobile payment, the format that has become prevalent in recent years. As such, this study focuses on security of using mobile payment and develops a benefit-cost appraisal and a trade-off framework by integrating the Theory of Reasoned Action (TRA), the Theory of Planned Behavior (TPB), the Protection Motivation Theory (PMT), and the Rational Choice Theory (RCT). Particularly, this study introduces security risk tolerance into mobile payment study and sets it as the dependent variable. This study proposes that consumers’ security risk tolerance is shaped by their benefit-cost appraisal and their tradeoff process, regarding the use of mobile payment.

Based on an online survey that collected data from 324 respondents in China, this study empirically tests and validates the research model. The findings suggest that consumers’ perceived benefit in using mobile payment is positively related to their security risk tolerance, whereas their perceived cost of using mobile payment is negatively related to their security risk tolerance. Convenience, safety, and savings positively affect consumers’ perceived benefit. The security threat positively affects consumers’ perceived cost. Payment tradition moderates consumers’ benefit-cost appraisal and trade-off process, but normative beliefs do not have a significant moderating effect. Self-efficacy only moderates the relationship between consumers’ perceived cost and their security risk tolerance. This study finds that males and females complete their benefit-cost appraisal and their trade-off process regarding security of using mobile payment very similarly. Gender differences only exist in the relationship between savings and consumers’ perceived benefit of using mobile payment.
