Indonesian people should turn to mobile payments, which will have an impact on economic efficiency because physical money is inefficient in use today. This study aims to identify the structural effects of Diffusion of Technology (DOI), Extended Unified Theory of Acceptance 2 (UTAUT2), and Perceieved Technology Security (PTS) models on behaviour intention to adopt (BIA) to adopt e-wallet-based mobile payment applications at Go-Pay and OVO using Structural Equation Modelling (SEM) Method. The second objective is to make structural identification of the BIA influence on behaviour intention to recommend (BIR) for the use of e-wallet-based mobile payment applications at Go-Pay and OVO. The results achieved in this study is that the latent compatibility variable significantly influences the behavior intention to adopt (BIA) with a coefficient value of 0.330, whereas innovativeness and perceived technology security have a positive but not significant effect on BIA variables. The variable intention to recommend (BIR) is significantly and positively influenced by the latent BIA variable and has an effect of 0.880.
