The expansion of the Fourth Industrial Revolution and financial technologies (FinTech) has accelerated the transition toward a cashless society. Within this context, easy payment services have emerged as a major alternative to cash-based transactions. In South Korea, Big Tech platform companies such as Kakao and Naver have strengthened their market position by seamlessly integrating payment functions into their existing service structures, achieving both high usage levels and strong brand recognition.
In practice, the integrated nature of these platforms exposes consumers to payment services repeatedly across a wide range of everyday situations. As these experiences accumulate, engagement tends to deepen, and platform-based interactions begin to shape consumers’ decision-making processes over time.
However, despite this widespread diffusion, a clear gap remains between adoption and sustained use. According to Statista (2024), while 81.6% of respondents reported having used easy payment services within the past six months, only 27.5% indicated that they continue to use these services on a regular monthly basis. This disparity suggests that consumers’ initial acceptance does not necessarily translate into continuous usage. Rather, the relatively low level of sustained use indicates that adoption cannot be explained solely by early-stage usage intentions, but appears to be grounded in longer-term, value-based evaluations.
Moreover, as consumers repeatedly interact with platform-based services and encounter personalized recommendation features, they gradually become more familiar with the platform and develop a sense of trust. Over time, this psychological foundation may evolve into emotional attachment and affective bonds, ultimately leading to more favorable evaluations of service value. Against this backdrop, the present study moves beyond prior discussions that have primarily focused on the functional attributes of easy payment services. Instead, it jointly considers perceived platform characteristics and platform–consumer interaction processes, with the aim of identifying the key factors that shape consumers’ perceived value in the context of platform-based easy payment service usage.
To achieve this objective, an online survey was conducted among consumers aged 19 to 69 who had used platform-based easy payment services within the past three months. For data collection, the study relied on Macromill Embrain, a professional research agency in South Korea. After screening the responses, a total of 300 valid questionnaires were retained for the final analysis.
The major findings and implications of this study can be summarized as follows. First, consumers tended to use platform-based easy payment services not as a complete substitute for traditional payment methods such as credit cards, but rather as a complementary option used alongside them. In practice, a substantial proportion of respondents reported using these services at least once or twice per week. Usage was concentrated primarily in everyday consumption settings, including convenience stores, restaurants, and cafés.
Among the various usage purposes, online shopping accounted for the largest share. This pattern suggests that platform-based easy payment services exhibit particular strengths in digital purchasing environments. Regarding transaction size, the average payment amount per transaction was largely centered on small expenditures ranging from KRW 10,000 to 50,000, while the maximum acceptable payment amount generally remained below KRW 100,000.
Taken together, these findings indicate that platform-based easy payment services are predominantly used in routine consumption contexts involving small- to medium-sized transactions.
Second, usage patterns differed markedly according to demographic characteristics and usage experience. Male respondents primarily relied on credit cards, whereas female respondents showed a stronger preference for Naver Pay and were more actively engaged in small-scale transactions. Younger consumers tended to prefer Kakao Pay and Naver Pay, while older users predominantly relied on credit cards. As income levels increased, consumers were more likely to adopt multiple payment methods flexibly.
Educational differences were also observed. Respondents with a college degree or higher mainly used platform-based easy payment services for shopping, whereas those with a high school education or below more frequently used them for daily services and leisure-related activities. In addition, younger users exhibited higher average transaction amounts and higher acceptable maximum payment levels, suggesting a greater openness to using easy payment services for higher-value transactions and incorporating them into routine consumption.
Differences also emerged with respect to usage experience. In particular, Naver Pay was most frequently used for shopping, whereas Kakao Pay was more commonly associated with financial transactions such as bill payments. High-frequency users engaged in higher-value transactions and primarily used easy payment services in everyday settings such as convenience stores, cafés, and restaurants. By contrast, low-frequency users tended to limit their use to small transactions and demonstrated more sporadic usage across diverse contexts, including karaoke rooms, traditional markets, and small retail shops.
Third, consumer perceptions of platform-based easy payment services varied across demographic and experiential characteristics. Female respondents reported stronger perceptions of interactivity, while male respondents evaluated security more positively. Younger consumers generally reported higher evaluations across key service attributes, including expandability, interactivity, familiarity, personalization, pervasiveness, responsiveness, and engagement. Differences were also observed by socioeconomic and regional characteristics: higher-income users placed greater emphasis on convenience, whereas residents in non-capital regions tended to prioritize security, and those in capital regions valued responsiveness more highly.
Usage experience further differentiated consumer perceptions. Frequent users—defined as those using the service three to seven times per week—reported the highest levels of perceived platform characteristics, engagement, and perceived value. In a similar vein, consumers willing to accept payments exceeding KRW 1,000,000 tended to report consistently strong evaluations across all service dimensions. Differences by average transaction value were most pronounced in evaluations of security, with consumers spending over KRW 100,000 assigning the highest ratings. In addition, consumers who primarily relied on platform-based easy payment services reported higher perceptions of familiarity, personalization, pervasiveness, convenience, responsiveness, engagement, and perceived value than those who mainly used traditional payment options.
Fourth, among the platform characteristics examined, pervasiveness, personalization, familiarity, and interactivity were found to enhance Platform Engagement, whereas service expandability did not show a statistically meaningful effect. Functional attributes, including convenience, security, and responsiveness, directly and positively influenced perceived value. Platform Engagement itself also showed a strong positive association with perceived value, illustrating how psychological and behavioral responses generated through platform interactions can translate into consumers’ perceptions of service value.
Moreover, most platform characteristics appeared to influence perceived value indirectly through Platform Engagement. More specifically, pervasiveness and familiarity exhibited full mediation effects, while personalization and interactivity demonstrated partial mediation effects.
Based on the findings of this study, several practical implications can be drawn.
First, service providers should move beyond simply expanding payment functions and instead place greater emphasis on strengthening consumers’ perceived use value throughout the usage process. From a practical standpoint, this involves identifying the diverse needs of different consumer segments and designing services in ways that allow the platform’s benefits to be clearly recognized. In addition, providers need to establish structural conditions through which enhanced value perceptions can be more naturally translated into stronger Platform Engagement.
Second, strategies aimed at strengthening Platform Engagement should not rely solely on increasing the number of features or expanding service scope. Rather, service providers are required to develop a more nuanced understanding of the contexts in which consumers use the service and the expectations they hold in those situations, and to reflect these insights throughout the service design process. In particular, attention should be given to enhancing the quality of platform interactions and offering personalized functions that align with users’ characteristics and situational needs. At the same time, usage experiences should be designed in a way that allows brand familiarity to accumulate gradually, while ensuring that services can be seamlessly integrated into everyday consumption contexts.
Third, although the findings confirm that platform characteristics play an important role in enhancing user experience, it is also necessary to pay close attention to the functional attributes that form the foundation of easy payment services. These core functions exert a direct influence on consumers’ value evaluations. Only when such functions operate stably and reliably, supported by continuous management, can consumers develop trust in the service as a whole. From a managerial perspective, this highlights the importance of sustained efforts to maintain technical performance and ensure consistent quality management.
