Can i load the Octopus Card with USD? We will be in HK for 6 days during Christmas this year.

Hi, dear! Upon landing, you can see an Airport Express round counter, where you can buy a standard Octopus card. Each adult pays HKD 50 as the deposit, and HKD 100 as the stored value; each child aged 3 to 11 pays HKD 50 as the deposit, and HKD 20 as the stored value.

I am afraid that you cannot load the card with USD. You should use HKD instead. You may convert your currency into HKD at the airport. Don't worry! :)
