The aim of this research is to test the applicability of the Unified Theory of Acceptance and Use of Technology (UTAUT) in relation to employees' intention to accept IR 4.0. In the context of this research, the UTAUT variables of performance expectancy and effort expectancy are examined to test their relationships with employees' acceptance of IR 4.0 in Malaysia, with behavioural intention acting as a mediator. A total of 337 questionnaires were distributed among Small and Medium Enterprises (SMEs) in Penang Halal industry.
