These custom full colour wristbands are usually issued at the entry point to the event just before the start of the event. This in turn makes it next to impossible for gate crashers to duplicate a wristband in advance. Guests are usually instructed to wear the wristbands until they exit the event. The full colour wristband not only makes it easy to identify bonafide guests, the colour of the wristband helps keep them confined to their section of the event.
