No, you must keep it.
Entering the booths and areas hosting the events is permitted only to holders of a regular access ticket consisting of a ticket (daily or multiple days ticket) with the related bracelet, that must be kept in sight at all times at all the entrances to the pavilions.
The entry ticket must be kept until the end of the event and the exit from the sites above. The ticket or the subscription loses its validity once its coverage period has expired.
