Mobile phones have evolved from basic communication tools to multi-functional devices.During this evolution, new services and facilities provided by mobile phones have brought newchallenges to understand consumer adoption processes – initially the basic concept of a mobilecommunication tool and subsequently mobile Internet browsing, social media tools and onlinegaming, among others. This paper focuses on a more recent innovation for which likelyconsumer adoption processes are poorly understood – mobile payment (m-payment) systems.M-payments also referred to as mobile money, virtual, digital or mobile wallets, can bedefined as financial transactions such as “payments for goods, services, and bills with a mobiledevice (such as a mobile phone, smart-phone, or ... [tablet]) by taking advantage of wireless andother communication technologies” (Dahlberg, Mallat, Ondrus, & Zmijewska, 2008, p. 165). Mpayment services can be distinguished from a number of services, such as mobile ordering(where a mobile device is only used to initiate an order but not for payment), mobile delivery(where a mobile device is only used to receive delivery of digital services), mobile authentication(using a mobile device to authenticate a user), and mobile banking (accessing bankingfunctionalities via a mobile device).
