Card transactions by proxy

[Mary Hawking]

Every online transaction I make seems to ask for the security code - I'd
supposed it was in place of the PIN.
Is it just asked for on Visa cards?

My recollection of booking hotels online is that it's unusual for them to
want the CV2, even for "payment even if you don't show up" special offers.
I've always assumed that as their relationships with credit card companies
are amongst the oldest, and the whole issue of things like "reserving
credit" is there for the hotel industry's benefit (and car hire, I guess),
they play by different rules.
