When you come to study at IED you will be given a student card. With this card, you are entitled to discounts at various companies with which IED has a cooperation agreement.
At the entrance to IED is a security turnstile, through which only those who have an official IED card can enter freely. So, whenever you enter or leave the building, you must have your card with you to be able to open the gates.
In the mediateca (multimedia library) your card will also allow you to make photocopies and printouts and act as a pre-paid card that you can top up.
