What is 國泰世華 CUBE App?
CUBE is a Cathay United Bank app that guides you through registration or account opening. The invite link on this page opens a campaign page and leads you to the app download. It already carries invite code H21AU, which may be filled in automatically; if the invite code field is empty, enter it yourself.
Before you submit anything, check that the address domain belongs to the bank and that the code in the field matches the one on this page. You can also copy the code here first and paste it when the app asks.
