This study aims to analyze the effect of member card usage on customer satisfaction at Bolly Department Store in Bima City. The research applied a quantitative approach with a survey method, where data were collected through questionnaires from 96 respondents selected using purposive sampling, specifically customers who owned a member card. The research instrument was tested using validity and reliability tests to ensure accuracy and consistency. Data were analyzed using simple linear regression, correlation coefficient, coefficient of determination, and t-test with the assistance of SPSS software. The findings indicate that the member card variable has a positive and significant effect on customer satisfaction. This is evidenced by the t-test result, where the t-value (1.894) exceeded the t-table value (1.661). However, the coefficient of determination (R²) was only 0.029, meaning that the member card explains merely 2.9% of the variation in customer satisfaction, while 97.1% is influenced by other factors. Therefore, although the member card improves customer satisfaction, its contribution is relatively small, suggesting that additional and more comprehensive marketing strategies are needed.
