Understanding user acceptance of QR code mobile payment systems in Turkey: An extended TAM

With the contactless payment feature, QR code mobile payment systems (MPS) has been increasingly popular among consumers, particularly during the COVID-19 pandemic. These systems enable consumers to shop from their mobile devices and complete payment transactions quickly. This research aims to explain the user acceptance of QR code MPS and identify the causal relationships between the factors affecting the acceptance. An extended Technology Acceptance Model (TAM) was proposed to achieve this. The research data was obtained from 485 QR code MPS users in Turkey using an online survey. The remarkable findings of the research showed that the most crucial determinant of the intention to use (IU) is perceived trust (PT), followed by perceived compatibility (PC) and perceived usefulness (PU). Although some of the variables included in the current study were also included in some past studies, no study in the area of QR code mobile payment adoption includes all our variables. In addition, the proposed model explains 65 % of the variance in intention to use QR code MPS (a higher value than the past studies). Therefore, it is expected that the results of this study will be useful in making inferences for countries with similar characteristics.

An intelligent approach for analyzing the impacts of the COVID-19 pandemic on marketing mix elements (7Ps) of the on-demand grocery delivery service.

Due to the impact of the COVID-19 pandemic, on-demand grocery delivery service that combines mobile technology and city logistics has gained tremendous popularity among grocery shoppers as a substitute to self-service grocery shopping in the store. This paper proposes an intelligent comparative approach where fuzzy logic and the analytical hierarchy process (AHP) method are combined to determine the importance weights of the criteria for marketing mix elements (7Ps) of the on-demand grocery delivery service for the period before COVID-19 and during COVID-19. In addition to its comprehensive theoretical insight, this paper provides a practical contribution to decision makers who create a marketing mix for the on-demand grocery delivery service and other similar online grocery businesses in terms of efficient allocation of resources to the development of marketing mix elements. The study's findings can also provide clues for the decision makers in times of similar pandemics and crises that are likely to be seen in the future.
