the passport account is totally aimed at travellers and can be opened once you’ve landed in London or even before you go, online. if you do apply for the account online make sure you are landing in the UK within 3months of applying for the account otherwise it gets cancelled.
the account is a 12 month long account. it will cost you 6 quid a month to have and you will get a debit card to access your funds.
that’s it. basic account, basic access. after 12months HSBC will upgrade you to a better account that has better fees and better access.
