The availability of a huge number of studies about the Technology Acceptance Model (TAM) for predicting consumer's acceptance and usage of innovations in points of sale motivates writing of the present. Review, with emphasis on the new variables integrated in the traditional model. This is concerned with a synthesis of the current progresses in the field, thus offering a unified view of consumers' behaviour towards new technical solutions. Such synthesis is achieved from an extensive literature analysis, including computer science, innovation, human-computer interaction, and technology management perspectives. For each case, both opportunities and issues are outlined in order to advance the current knowledge and highlight what practitioners and scholars should take into account for developing new and efficient corporate strategies. ly applied also at retailing and consumers' usage of a new system in the points of sale (Pantano and Servidio, 2012). Hence, there is a huge amount of studies on the extended TAM, thus the need of a review able to synthesis the current progresses in this direction emerges for proposing a unified view of consumers' behaviour towards the new technical solutions in the points of sale. The aim of this paper is to provide a more comprehensive view of current researches in marketing and management studies, by reviewing the extant literature on TAM for advanced technology-based innovations for retailing including computer science, innovation management, human-computer interaction, and technology perspectives. We pursue this objective by reviewing studies that provide summaries of the variables and key findings of papers that directly address TAM. To achieve this task, we outline opportunities to enrich the knowledge of the phenomenon along with issues that practitioners and scholars should take into account for the development of new and efficient corporate strategies.The first part of the paper is devoted to the definition of emerging lines of inquiry and discussions of the theoretical contributions to the overall understanding of the phenomenon; whereas the second one focuses on the avenues for future perspectives, research methods and directions, suggestions on possible overviews for improving understanding of theoretical and practical issues emerged from the analysis.
Conceptual frameworkIn the last decades an important line of inquiry focused on users' acceptance of new technologies has emerged, by understanding the main variables able to predict the actual usage of a system, in order to properly tailor new services and products to the market based on Technology Acceptance Model (Davis, 1989). In fact, literature proposes a wide range of successful applications at several sectors, such as e-learning (Liu et al.
