The Pink ID card has already proved it’s worth oh mystic one as I’ve explained previously. Or maybe you prefer carrying your passport about in a man bag? I’ve no doubt the Yellow Book will prove it’s worth too but I’ll speak from experience on that rather than make an unresearched statement. BTW the Pink ID card was received through the same process that the Yellow card was so came as a package that didn’t require further bureaucracy to obtain.
Thinking back, the reason I decided to apply for the Yellow House Book now, rather than later, is that it was mentioned by a local branch of the SCB as being a requirement for opening a bank account with them.
