Technology Acceptance Model: A Case Study of Palm Vein Authentication Technology

Biometric authentication is a new technology that verifies an individual’ s identity via their unique physical or behavioural characteristics including Palm Vein or hand geometry. Despite its potential benefits and growing popularity in the public and private sectors, end-user adoption of the technology has been relatively slow. This study aims to investigate the major factors that influence Palm Vein biometric authentication devices through Technology Acceptance Model (TAM). In addition to the major TAM constructs, we postulate that the trust in the device, the users’ perception of risks involved, their perceived enjoyment during device utilization and their innovative nature to have a significant influence on their final adoption behaviour. Data was collected from 100 voluntary participants by offering them a chance to interact with a palm vein scanner connected to a coffee machine which was used for access authentication. The goodness-of-fit of the data to the model is validated and the proposed model and the hypotheses are evaluated using Structural Equation Modelling (SEM). The results confirm the influence of users’ risk perception, trust, and enjoyment factors on biometric technology adoption. Furthermore, this study shows that while risk perceptions and privacy concerns were found to be the primary hindrance to users’ intention to accept Palm Vein technology, building a sense of trust among its users and designing an endearing system has a substantial role in increasing their level of technology acceptance.
