Home FAQ I’ve been given an Iscte card and it’s already registered in the system. How long does it take to become active? PT Target Audience: Iscte-IUL CommunityAnswer/Solution: As a rule, the Iscte card becomes active, i.e. can be used, after 5 minutes. If this doesn’t happen, there will be a new activation during the night. Related Previous How can I access my institutional email? Next What types of RFID readers are there at Iscte?
