When planning a large event, crowd control is usually a primary concern. This is especially true of events at which alcohol will be served or if an entry fee will be charged. Keeping track of the guests who are in compliance with the event's rules and distinguishing those who have not yet paid the admission fee or presented required ID can be extremely difficult. In situations like these, wristbands can be a cost-effective, easily identifiable option. Furthermore, event coordinators may use wristbands in multiple colors if there is a need to divide the crowd into groups. With a wide variety of colors, materials, patterns, and even customization options available, wristbands can be made to match the theme and decorative requirements of virtually any occasion.
