Re: You needed to have multiple forms of ID
Still do need multiple ID to open an account, or to get additional ID (new Social Services Card or driving licence), inc utility bills to your address in Ireland. Then they post to the address. Some ID only accepted if you have Birth Cert too. EU anti-money-laundering laws. Preventing Money Laundering doesn't seem to apply to activities of major London based Financial institutions or major international companies stockpiling money in places like UK controlled Bahamas.
Now which pocket is my passport? Some countries even belatedly plugging hole of using dead people's birth cert to get passport. (see this 1971 manual)
