The effect of blockchain awareness on passengers' intention to use biometric technologies at Istanbul Airport

This study measures the intention to use biometric technologies of passengers using Istanbul Airport and the effect of awareness about blockchain technologies on this intention. Biometric technology can be described as the technology to identify a person using biology. Biometric technologies can collect this information and create a person's natural identity card. This information created by biometric technologies is more natural, safer, and more accurate. As these technologies collect sensitive information, the security of these technologies has become just as important. At this point, blockchain comes to the fore to ensure the safety of these technologies. For this purpose, biometric applications in airports, their examples, and the development of these applications are emphasized. Afterward, the place and importance of blockchain technology in biometric applications are emphasized. In order to measure the users' intention to use these technologies, a survey study was conducted at Istanbul Airport, and the results were evaluated. There are several models developed to understand the link between individual acceptance and the use of information systems. Venkatesh et al.'s (2012) UTAUT2 model has been widely accepted. The model used in this research is based on Morosan's (2016) model created according to UTAUT2. Accordingly, it is asked about the performance expectancy of biometric technologies, the effort expectancy of biometric technologies, the privacy concerns of passengers, air travelers' information sensitivity, air travelers' compatibility, and air travelers' knowledge about blockchain. The effects of these concerns on the intention to use biometric technologies are evaluated. In order to assess the relationship between this information and intention, structural equation modeling is used.
