Hi Mick,
Firstly, it wasn't me who mentioned the I Card but for FWIW, I spoke to BPI Europe this morning re opening an account with their London branch and another with them in sunny Dipolog. It seems easy enough to do both and I was assured that I WOULDN'T need an I Card to open one in Dipolog.
I know this has no bearing on whatever HSBC stipulate but it may be another option for you. I didn't look at HSBC because while there are many banks in Dipolog, HSBC isn't one of them.
How are things in Bradford? I'm in Wakefield and I have spent many a happy hour in the "Kash"!
Bill
