Refund your Octopus Card Landside
This is not so much a warning and danger but a don't forget to do this.The octopus card that just about every visitor to Hong Kong should have comes with a $50 HKD deposit per card. If you want to refund that deposit and also the current balance on your card before heading home, you need to do this landside in the airport before you go through immigration and security.If you forget, the card should be active for 3 years. The balance remaining I am not sure.
