In Scenarios of door access

1. I put the CU Link and an Octopus card in my wallet and I am unable to get through the gate. Why does that happen?
2. Why I am not able to get through the door as I suppose to?
3. What should I do when the error message showing “ Card locked” comes up at the reader of the door lock?

This is a feature intentionally adopted in many contactless smart card reader systems. You may visit the website of Octopus on the proper use of Octopus cards.

Please contact the corresponding departments/ service units for assistance if you can’t gain access to the door.

A “Card locked” message displayed at the reader of a door lock should mean that you had entered the wrong CU Link PIN many times, and the access function is blocked. CU-related functions will be blocked if you have entered the wrong CU Link PIN 5 times. You will not be able to use most CU Link related application then. Please go to the CU Link Card Centre [MAP] to reset your CU Link PIN.
