Increasingly, mobile technology is becoming common in our everyday lives (GFT Technologies, 2016); nevertheless, mobile payments are not one of the most frequently used mobile services (Liébana-Cabanillas, Muñoz-Leiva & Sánchez- Fernández, 2017). Peer-to-peer mobile payment services (P2PM-pay) (also referred to as person-to-person transactions or P2P transactions) allow customers to quickly and easily transfer funds from their bank account or credit card to another individual's account via the internet or a smartphone. Prior studies on payment systems using mobile devices focused on analyzing other types of payment systems, the internal structure and safety protocols for each system, and their adoption by consumers (Ramos-de-Luna, Montoro-Ríos & Liébana-Cabanillas, 2016; Ozturk, Bilgihan, Salehi-Esfahani & Hua, 2017).

The aim of this research is to propose a standardized behavioral model of users’ intention to use P2PM-pay. The model has been defined based on a framework involving some of the main theories of technologies adoption from the perspective of social psychology (Fishbein y Ajzen, 1975; Davis, Bagozzi & Warshaw, 1989; Venkatesh & Davis, 2000; Venkatesh & Bala, 2008; Venkatesh, Thong, & Xu, 2012). Based on the literature review and in-depth interviews conducted of professionals from the Fintech (financial technology) sector, the model was structured based on three groups of antecedents (i.e., drivers, inhibitor and psychological dimensions) to explain the intention to use.

The model was evaluated using survey data of 701 participants with structural equation modelling (SEM) approach. The proposed model is based on classical technology adoption models but incorporates specific variables from mobile payment systems. It includes a total of eight antecedents of the intention to use the P2PM-pay app. Among these antecedents, three (i.e. perceived usefulness, subjective norms and personal innovativeness) are fundamental to the intention to use, while three others (i.e. individual mobility, perceived risk and perceived trust) have a lesser influence. The results also point out that the relationships of both perceived ease of use and hedonic motivation with the intention to use are not significant. Based on the findings, this research has important theoretical and practical implications in understanding the adoption of P2P mobile payment services.
