Latest CU Link Design for Students & Staff 

The Smart University ID Card – CU Link 

CU Link is designed to be an all-in-one card for university students and staff. The incorporation of contact and contactless capacities make CU Link a truly multi-functional smart card, an effective and convenient digital device that you carry on and off the campus. CU Link could be used to access different services and facilities at various locations, for example, the University libraries, computer laboratories, sport centres and hostels. Applications of CU Link include identity authentication, physical access control, administrative transactions and electronic payment.

For more technical information please refer to Technologies Section.

Organization responsible for CU Link

The Chinese University of Hong Kong is responsible for determining the eligibility of an individual to obtain a CU Link. Information systems and access control systems making use of CU Link implemented on campus are deployed and managed by the University.

10-digit Student ID (effective from 1 July 2010)

Starting from 5 July 2010, all new CU Link issued for students are assigned with a unique 10-digit University Student ID (USID). This USID is used for students’ different stages of studying at the University, and even after graduation. Besides, to be environmentally responsible, we would not request current students to replace their CU Link due to the change in USID format.

*Please be noted that Staff ID is not affected and it is kept in the format of 6 characters.
