KAU ID is the official mobile student card and identification app for Korea Aerospace University students, faculty, and staff. With the KAU ID app, users can access library resources, reserve study rooms, and use the mobile student card for various on-campus transactions, including seat assignments and equipment rental.

To receive a KAU ID, users must log in to the app with their portal system account information and request the card. Once issued, students can use their QR student card or NFC student card to authenticate their identity for various on-campus services.

It's important to note that users must have a portal system account and a previous record of a student ID card to receive a KAU ID. Additionally, the mobile phone number used to receive the KAU ID must be registered with the portal system. In case of loss, users must report the loss through the Smart Campus Integrated Service website.

Please note that only Android devices with HCE support and running 4.4 or higher can use the NFC ID functionality. Overall, the KAU ID app offers a convenient and secure way for KAU students, faculty, and staff to access on-campus resources and services.
