“…The research was mostly based on the technology acceptance model (TAM) [16] and diffusion of innovations model [73]. The analysed studies often used the models as the base of their research, investigating whether the models' theoretical constructs are also likely to influence the intention to use, and the actual use of a mobile payment service (e.g., [7,8,13,14,34]), or examining whether consumers are ready to adopt mobile payments based on the assumed factors [17].
