Mox 咁寫:
We will not charge you if you send/ receive US dollars from/into your Mox Account to/from other banks via Real Time Gross Settlement (RTGS) system, but please note that other banks may have different charging policies.
HSBC 咁寫:
For US dollars and Euro domestic payments to other local banks, you need to make a transfer via the payee's account number and we will send the money via Real Time Gross Settlement (RTGS)*
* There is no charge from us if you pay money to, or receive money from accounts from other banks via FPS or RTGS, but other banks may have different charging policies.
