|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.
