If you want to eat in the canteen, go directly to the canteen and find someone to help you swipe your card. You can give money to others, which usually helps. In addition, HKUST has a Wan Xiu canteen on the fourth floor. No need to swipe your card. If you want to eat for a long time, it seems that you can get a meal card for people who are not in our school, and you only need to charge a little extra.
