The main aims of this paper are also to explore the variables suggested by consumer beliefs to form the expected hypothesis to be implemented in these studies. The cashless transaction model will be studied based on attitudes to identify the value of beliefs and best practices among consumers. Based on this attitude, the conceptual framework of the cashless transaction focuses on cognitive value through the factors of belief in cashless transactions.
