How does the electronic bracelet work?

At the time of access, an electronic bracelet is provided which is used to:
– access the entrance turnstiles (calculating the time of stay).
– open and close the lockers in the changing room area. Only one locker is connected to each bracelet. Also available in the pool area are bracelet readers that allow you to check the locker number in which your personal belongings are stored.
– charge all extra consumptions (food, drinks or access to extra areas), then paying any amount at the Reception.
