회원제, or "membership system," refers to a structure where individuals join an organization or service by paying a fee or meeting specific criteria. This system is commonly used in various sectors, including gyms, clubs, and online platforms, to provide exclusive access to services, benefits, or products. In a 회원제, members often receive perks such as discounts, special events, or personalized services. This model encourages loyalty and community among members, as they share common interests or goals. Examples of 회원제 include fitness centers, book clubs, and subscription services.
