Just walk out technology (JWOT) is one of the latest innovations in the retail business. This is the first empirical study done to predict Thai consumers' attitudes and intentions to use JWOT. Bangkok is not only known for rising urban development but also the market tester for many fast-moving consumer products. The purpose of this study is to find the important factors and explain the relationship between these factors towards the attitude and behavioural intention to use JWOT among consumers in Bangkok, Thailand. Data was collected through an online questionnaire from 400 respondents who reside in Bangkok. The findings show the relationship between the original TAM constructs and one external factor (social norm). However, perceived entertainment value, trust, and technology anxiety are not significant in the prediction of JWOT adoption. Differences in demographic characteristics and shopping habits were found to have effects on the overall technology acceptance.
