Students ID Cards are needed for students to use facilities on campus. Students can enter the Libraries and the Library Annex by using their student ID cards or mobile ID card with a QR code. They can also make seat reservations in the reading rooms in the libraries. After they verify their student ID, they can select the seat they want. If they press the seat number on a touch screen, the ticket will be printed. The student ID card is also needed for the dormitory system. With the cards, they can enter the Residence Halls and they can use the restaurant and convenience facilities in the dormitory.
