With the development of technology, mobile fingerprint instruments are now actively introduced to consumers as a secure and convenient solution to problems related to identity control and authorization verification management in m-payment systems. This study aims to reveal whether consumers’ inference about a tradeoff between convenience and security still influences today’s m-payment environments. A presumed research model was proposed and tested using structural equation modeling to explore the effects of perceived security, privacy, and convenience of Touch ID in-app payments on attitude toward and usage intention of the technology, mediated by perceived risk and trust. The results (n = 406) revealed that perceived privacy, security, and convenience of Touch ID in-app payments directly or indirectly influenced consumer attitude toward the technology, also trust and perceived risk significantly mediated the effects of such factors on attitude, predicting usage intention. These findings have important theoretical and practical implications, particularly for the development and marketing of retailer’s in-app payments.
