Wristbands do a specific job at events: they confirm that someone has paid, is old enough to drink, or is allowed into a particular area, without requiring staff to check tickets or ID repeatedly throughout the day. At busy events, that separation of entry from ongoing access saves a significant amount of time and argument.
For event organisers across Northern Ireland, from music festivals in the Sperrins to sports days in County Down and charity fundraisers in Belfast, the question is less whether to use wristbands and more which type suits the event.
