This study investigated the current status of cashless payments in Korea, where such payments are in the adoption stage, and examined the way this topic is treated in home economics textbooks. In addition to investigating how the topic of cashless payments is treated in Japanese high- school home economics textbooks, we conducted an attitude survey of Japanese high-school students in Korea. Given that conventional credit education emphasizes knowledge of the demerits of postpayment, there is a need for consumer education that can foster people’s ability to independently select cashless payments, including prepayment and on-the-spot payment, and that can encourage individuals to build their own credit history.
