Mobile contactless payments (MCP) technology brings an important dual use dilemma where consumer adoption can be halted if consumer is not fully persuaded that the security risk behind the technology use is very low. Currently, although many projects on the implementation of MCP solutions have commenced, MCP is still not picking up. Why? To fill this research gap and better understand how security is affecting MCP implementation, we employ triangulation approach to understand if security is the main obstacle to further adoption and extension of MCP solution. The results reveal that consumer security is the crucial factor in a successful MCP implementation. Our result offers important and new insights for practitioners as it provides a security dimension to consider in the entire contactless payment ecosystem.
