Home > About CU Link > CU Link PIN

There are two chips, one contact and one contactless, on your CU Link. A system generated random number is used as the PIN for each CU Link and that number is being stored in both the contact and contactless chips.

Each CU Link carries a different default PIN. To obtain the default PIN of both chips, please login the CU Link Default PIN Enquiry System (http://www.cuhk.edu.hk/culink/pin) with your Staff/Student ID and Campus-wide Email System (CWEM) password.

Location for changing CU Link PIN

Apart from CU Link Card Centre, you may change the PINs at the designated computer terminals in User Area on 1/F, Pi Chiu Building or Learning Commons on 6/F of Wu Ho Man Yuen (WMY) Building at any time.  The new PINs should contain 4 to 8 numeric digits. Please remember to change the PIN of both chips. [MAP]

Remarks: Some door access and payment systems may require users to press the "#" sign after entering the PIN.
