Purpose: The purpose of this paper is to develop and test a theoretical framework explaining the adoption of online insurance claims characterised by infrequent interactions, inherent complexity and risk. It extends the technology acceptance model to include knowledge-related and trust-related beliefs. Design/methodology/approach: The framework is tested with structural equation modelling using data from a survey of 292 customers who made online insurance claims. Findings are further explained through 30 telephone interviews conducted with online and offline claimants. Findings: Previous research in financial services has shown trust to be equally or more important than perceived usefulness and perceived ease of use in forming attitudes towards adopting online insurance applications. The findings of this paper contradict this by showing, at best, a weak relationship between trusting attitude and intention to use the online service. Trust is somewhat meaningful; however, perceived ease of use, perceived usefulness and technology attitude are substantially more important in an online insurance claims setting. Research limitations/implications: Contradictory results always beg further research to assure their robustness. Nevertheless, they can also point to a developing trend where trust in the internet channel, per se, is of diminishing importance. Internet and product knowledge are not as pertinent to forming intentions as usefulness and ease of use. Practical implications: To encourage customers to adopt online applications for a trusted company, all emphasis should be on user friendliness and perceived usefulness of the online interface. Originality/value: Compared to other channels, consumers are no longer naïve or distrustful of the online channel for interacting with a firm. If they perceive usefulness and ease of use, they will adopt the offered service.
