If you want to have smooth access to the gym, please come register your ISIC or school card tomorrow (11th July) to the admin's office (SIN, 5th floor, from 8pm). We'll be registering in a testing mode.
Can't make it? No worries, you can still leave dormitory cards at a reception and receive a key. However, you won't be able to pass the door if there's already someone in the gym, because you won't receive a key in that case, and without a key/card, you won't be able to open the door. Unless someone from the inside opens it for you.
You'll need at least two people (two cards) to enter the gym, which is similar to the current system, where you have to leave two dormitory cards at the reception.
