The maximum balance limit for your Smart Account is HKD10,000. In order to provide a better experience for receiving payments, if your Smart Account is set up as the FPS receiving account and you are receiving a transfer that would cause your balance to exceed the balance limit, the system will automatically transfer the full amount of the funds to your Master Account.
If your Payment Account is set up as the FPS receiving account, the maximum balance limit (up to HKD10,000) cannot be exceeded when the payer transfers funds to your Payment Account.
