This study aims to explore the structural relationships between older customers' technological self-efficacy, personal innovativeness, perceived values (social, utilitarian, hedonic), attitudes, and behavioral intentions regarding technology-based, contactless services in hotels and restaurants. The survey, based on previous research, targeted customers over 50 who have experience using Self-Service Technologies (SST) in the hotel and restaurant sector, with a final valid sample of 228 respondents included in the analysis. The conclusions from this study's hypothesis testing are as follows: First, senior customers' technological self-efficacy positively impacts utilitarian value but negatively impacts social value. However, it does not significantly affect hedonic value or behavioral intentions. Second, personal innovativeness positively impacts social, utilitarian, and hedonic values, with the most significant enhancement observed in hedonic value. It also significantly influences behavioral intentions. Third, while utilitarian and hedonic values positively affect attitudes, social value does not have a significant impact on attitudes. Fourth, the attitude of senior customers towards SST positively influences their behavioral intentions. These findings suggest that efforts to enhance the technological self-efficacy of the senior customer segment could strengthen functional interactions with technology, thereby enhancing the adoption intentions of SSTs in the hotel and restaurant industries.
